All methods on \fBSoDB\fP are static\&. .PP Make sure you call \fBSoDB::init()\fP (either directly or indirectly through the \fBinit()\fP method of the GUI glue library) before you use any of the other Coin classes\&. .SH "Member Typedef Documentation" .PP .SS "SbBool SoDB::ProgressCallbackType" Client code progress callback function must be static functions of this type\&. .PP The \fIitemid\fP argument is a unique text identifier which says what is being processed (use this for any GUI progress bar informational text), and \fIfraction\fP is a value in the range [0, 1] which indicates how far the process has got\&. If the task is successfully aborted, the callback will be invoked a last time with \fIfraction\fP set to -1\&.0\&. .PP The return value is an abort flag indication from the client code\&. Note that the process that is being run can only be aborted if the \fIinterruptible\fP flag is set\&. .PP See \fBSoDB::addProgressCallback()\fP for full documentation of how the progress notification mechanism works\&. .SH "Member Function Documentation" .PP .SS "void SoDB::init (void)\fC [static]\fP" Initialize the Coin system\&. This needs to be done as the first thing before you start using the library, or you'll probably see an early crash\&. .SS "void SoDB::finish (void)\fC [static]\fP" Invoke this method as the last call of the application code, to trigger a clean-up of all static resources used by the Coin library\&. .PP This is usually not necessary for stand-alone executable applications, as the operating system will take care of cleaning up after the process as it exits\&. .PP It may be necessary to invoke this method to avoid leaks for 'special' execution environments, though, like if the Coin library is used as e\&.g\&. a browser plug-in, or some other type of component which can be started, shut down and restarted multiple times\&. .PP \fBSince:\fP .RS 4 Coin 2\&.4 .PP TGS Inventor 5\&.0 .RE .PP .SS "void SoDB::cleanup (void)\fC [static]\fP" This method was renamed from Coin version 2\&.4 onwards, to \fBSoDB::finish()\fP\&. Consider this name for the method obsolete\&. .PP \fBSince:\fP .RS 4 Coin 2\&.0 .RE .PP .SS "const char * SoDB::getVersion (void)\fC [static]\fP" Returns a text string containing the name of the library and version information\&. .SS "SbBool SoDB::read (\fBSoInput\fP *in, \fBSoPath\fP *&path)\fC [static]\fP" Instantiates and reads an \fBSoPath\fP object from \fIin\fP and returns a pointer to it in \fIpath\fP\&. .PP The reference count of the \fBSoPath\fP object will initially be zero\&. .PP Returns \fCFALSE\fP on error\&. Returns \fCTRUE\fP with \fIpath\fP equal to \fINULL\fP if we hit end of file instead of a new path specification in the file\&. .SS "SbBool SoDB::read (\fBSoInput\fP *in, \fBSoBase\fP *&base)\fC [static]\fP" Instantiates and reads an object of type \fBSoBase\fP from \fIin\fP and returns a pointer to it in \fIbase\fP\&. \fIbase\fP will be \fCNULL\fP on return if we hit end of file\&. .PP The reference count of the base object will initially be zero\&. .PP Returns \fCFALSE\fP on error\&. .SS "SbBool SoDB::read (\fBSoInput\fP *in, \fBSoNode\fP *&rootnode)\fC [static]\fP" Instantiates and reads an object of type \fBSoNode\fP from \fIin\fP and returns a pointer to it in \fIrootnode\fP\&. .PP The reference count of the node will initially be zero\&. .PP Returns \fCFALSE\fP on error\&. Returns \fCTRUE\fP with \fIrootnode\fP equal to \fCNULL\fP if we hit end of file instead of a new node specification in the file\&. .SS "\fBSoSeparator\fP * SoDB::readAll (\fBSoInput\fP *in)\fC [static]\fP" Reads all graphs from \fIin\fP and returns them under an \fBSoSeparator\fP node\&. If the file contains only a single graph under an \fBSoSeparator\fP node (which is the most common way of constructing and exporting scene graphs), no \fIextra\fP \fBSoSeparator\fP root node will be made, but the returned root node will be the top-most node from the file\&. .PP The reference count of the root separator returned from this method will be zero\&. Other nodes in the returned scene graph will have reference counts according to the number of parent-child relationships, as usual\&. .PP The common layout for how to load, work with and then finally destruct and return memory resources of scenegraphs usually goes like this: .PP .PP .nf // [snip] SoInput in; if (!in\&.openFile(filename)) { exit(1); } SoSeparator * root = SoDB::readAll(&in); if (!root) { exit(1); } // root-node returned from SoDB::readAll() has initial zero // ref-count, so reference it before we start using it to // avoid premature destruction\&. root->ref(); // [do your thing here -- attach the scene to a viewer or whatever] // Bring ref-count of root-node back to zero to cause the // destruction of the scene\&. root->unref(); // (Upon self-destructing, the root-node will also de-reference // it's children nodes, so they also self-destruct, and so on // recursively down the scenegraph hierarchy until the complete // scenegraph has self-destructed and thereby returned all // memory resources it was using\&.) .fi .PP .PP Returns \fCNULL\fP on any error\&. .PP Tip: a common operation to do after importing a scene graph is to pick out the memory pointers to one or more of the imported nodes for further handling\&. This can be accomplished by using either the \fBSoNode::getByName()\fP function (which is the easier approach) or by using an instance of the \fBSoSearchAction\fP class (which is the more complex but also more flexible approach)\&. .SS "\fBSoVRMLGroup\fP * SoDB::readAllVRML (\fBSoInput\fP *in)\fC [static]\fP" Same as \fBSoDB::readAll()\fP, except it return an \fBSoVRMLGroup\fP instead of an \fBSoSeparator\fP\&. .PP \fBSee Also:\fP .RS 4 \fBSoDB::readAll()\fP .RE .PP \fBSince:\fP .RS 4 Coin 2\&.0 .RE .PP .SS "SbBool SoDB::isValidHeader (const char *teststring)\fC [static]\fP" Check if \fItestString\fP is a valid file format header identifier string\&. .PP \fBSee Also:\fP .RS 4 \fBgetHeaderData()\fP, \fBregisterHeader()\fP .RE .PP .SS "SbBool SoDB::registerHeader (const \fBSbString\fP &headerstring, SbBoolisbinary, floativversion, SoDBHeaderCB *precallback, SoDBHeaderCB *postcallback, void *userdata = \fCNULL\fP)\fC [static]\fP" Register a header string which should be recognized by \fBSoInput\fP upon file import\&. This is a convenient way for library users to register their own VRML or Coin derived file formats\&. .PP Set \fIisbinary\fP to \fCTRUE\fP if the file should be read as binary data, and set \fIivversion\fP to indicate which Coin library version is needed to read the file\&. .PP Callbacks \fIprecallback\fP and \fIpostcallback\fP will be called before and after importing the custom format\&. .PP If \fIheaderstring\fP can not be accepted as a valid file format header for Coin files, \fCFALSE\fP will be returned\&. A valid header \fImust\fP start with a '#' character, and not be more than 80 characters long\&. .PP \fBSee Also:\fP .RS 4 \fBgetHeaderData()\fP .RE .PP .SS "SbBool SoDB::getHeaderData (const \fBSbString\fP &headerstring, SbBool &isbinary, float &ivversion, SoDBHeaderCB *&precallback, SoDBHeaderCB *&postcallback, void *&userdata, SbBoolsubstringok = \fCFALSE\fP)\fC [static]\fP" Returns the settings for the given \fIheaderstring\fP, if \fIheaderstring\fP is a valid header\&. .PP If \fIsubstringok\fP is \fCTRUE\fP, ignore trailing characters in \fIheaderstring\fP when checking for validity\&. .PP If no valid header string by this name is found, \fCFALSE\fP is returned, otherwise \fCTRUE\fP will be returned, and the other input arguments will be set to their respective values\&. .PP \fBSee Also:\fP .RS 4 \fBisValidHeader()\fP, \fBregisterHeader()\fP .RE .PP .SS "int SoDB::getNumHeaders (void)\fC [static]\fP" Returns number of registered file headers\&. .PP \fBSee Also:\fP .RS 4 \fBgetHeaderString()\fP .RE .PP .SS "\fBSbString\fP SoDB::getHeaderString (const inti)\fC [static]\fP" Returns the identifier header string of index \fIi\fP\&. .PP \fBSee Also:\fP .RS 4 \fBgetNumHeaders()\fP, \fBgetHeaderData()\fP .RE .PP .SS "\fBSoField\fP * SoDB::createGlobalField (const \fBSbName\fP &name, \fBSoType\fPtype)\fC [static]\fP" Create a new global field by the given \fItype\fP, and identified in subsequent accesses to \fBgetGlobalField()\fP by \fIname\fP\&. If a global field by the name and type already exists, returns a pointer to it\&. If a global field with the same name but a different type exists, returns \fCNULL\fP\&. .PP A global field can be deallocated by calling \fBSoDB::renameGlobalField()\fP, with the second argument set to an empty string\&. .PP \fBSee Also:\fP .RS 4 \fBgetGlobalField()\fP, \fBrenameGlobalField()\fP .RE .PP .SS "\fBSoField\fP * SoDB::getGlobalField (const \fBSbName\fP &name)\fC [static]\fP" If there exist a global field with the given \fIname\fP, return a pointer to it\&. If there is no field with this name, return \fCNULL\fP\&. .PP Of particular interest is the \fCrealTime\fP global field set up by the library on initialization\&. This field is used as a source field to all the autonomous animation objects within the library, like for instance the \fBSoTimeCounter\fP engine or the \fBSoRotor\fP node\&. .PP If you want to control the speed of 'action' of a scene with animating / moving components (for instance for doing fixed frame-time snapshots for generating a movie), grab the global field named 'realTime' and use it in the manner depicted in the class documentation of the \fBSoOffscreenRenderer\fP class\&. .PP \fBSee Also:\fP .RS 4 \fBcreateGlobalField()\fP, \fBrenameGlobalField()\fP .RE .PP .SS "void SoDB::renameGlobalField (const \fBSbName\fP &from, const \fBSbName\fP &to)\fC [static]\fP" Rename a global field\&. If \fIto\fP is an empty name, the \fIfrom\fP field gets deleted\&.

Default value is 1/12 s\&. .PP The low update rate is due to historical reasons, to be compatible with application code written for SGI Inventor\&. .PP Setting the interval to a zero time will disable automatic updates of the realTime field\&. .PP \fBSee Also:\fP .RS 4 \fBgetRealTimeInterval()\fP, \fBgetGlobalField()\fP .RE .PP .SS "const \fBSbTime\fP & SoDB::getRealTimeInterval (void)\fC [static]\fP" Returns the current trigger interval for the global \fIrealTime\fP \fBSbTime\fP field\&. .PP \fBSee Also:\fP .RS 4 \fBsetRealTimeInterval()\fP, \fBgetGlobalField()\fP .RE .PP .SS "void SoDB::enableRealTimeSensor (SbBoolon)\fC [static]\fP" Turn on or off the realtime sensor\&. .PP The most common use for turning the realtime sensor off is to control the realTime global field from the user application\&. This is for instance handy when you want to take screen snapshots at fixed intervals\&. See the class documentation of \fBSoOffscreenRenderer\fP for further information\&. .PP \fBSee Also:\fP .RS 4 \fBsetRealTimeInterval()\fP, \fBgetGlobalField()\fP .RE .PP .SS "\fBSoSensorManager\fP * SoDB::getSensorManager (void)\fC [static]\fP" Returns a pointer to the global sensor manager\&.

DON'T USE IT\&. .PP This is a wrapper around the POSIX \fCselect()\fP call\&. It is provided so you can do synchronous I/O while Coin continues to handle sensor events, rendering, etc\&. The parameters are the same as for \fCselect()\fP, so check your system documentation on how to use them\&. .PP The void* arguments must be valid pointers to fd_set structures\&.

DON'T USE IT\&. .SS "void SoDB::addConverter (\fBSoType\fPfrom, \fBSoType\fPto, \fBSoType\fPconverter)\fC [static]\fP" Notify \fBSoDB\fP that there exists a way to convert data from the \fIfrom\fP \fBSoField\fP type to the \fIto\fP \fBSoField\fP type, by connecting them with an instance of the \fIconverter\fP \fBSoFieldConverter\fP type\&. .PP By doing this, \fBSoDB::getConverter()\fP will later be able to automatically return the type of the correct conversion class when requested\&. .PP Coin internally provides conversion between most field types, so application programmers should usually not need to use this function\&. The exception is if you are writing your own field type classes, and want to be able to connect them to the internal field types (or other extensions field types)\&. .PP \fBSee Also:\fP .RS 4 createConverter(), \fBSoFieldConverter\fP .RE .PP .SS "\fBSoType\fP SoDB::getConverter (\fBSoType\fPfrom, \fBSoType\fPto)\fC [static]\fP" Return the type of an \fBSoFieldConverter\fP class which is able to convert data between fields of type \fIfrom\fP to the data field(s) of field type \fIto\fP\&. .PP If no conversion between the given field types is possible, returns \fBSoType::badType()\fP\&. .PP \fBSee Also:\fP .RS 4 \fBaddConverter()\fP .RE .PP .SS "SbBool SoDB::isInitialized (void)\fC [static]\fP" Returns \fCTRUE\fP if \fBinit()\fP has been called\&. .PP \fBSee Also:\fP .RS 4 \fBinit()\fP .RE .PP .SS "void SoDB::startNotify (void)\fC [static]\fP" \fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP .SS "SbBool SoDB::isNotifying (void)\fC [static]\fP" \fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP .SS "void SoDB::endNotify (void)\fC [static]\fP" \fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP .SS "void SoDB::addProgressCallback (\fBProgressCallbackType\fP *func, void *userdata)\fC [static]\fP" The concept behind progress information in Coin is that any internal process which may take a long time to complete (like e\&.g\&. file import for huge scenes) can pass on progress information by calling back to a progress callback set up by the code of the client application\&. .PP The client's progress callback's function signature must match the \fBSoDB::ProgressCallbackType\fP\&. .PP The mechanism works by enforcing that all progress notification from within Coin must .PP .PD 0 .IP "1." 4 Use a unique text id to identify the 'progress-informing' process (e\&.g\&.
