.SH "Detailed Description"
.PP 
The \fBSoShaderParameter\fP class is the base class for all shader parameter classes\&.
.PP
In addition to the \fIname\fP and \fIidentifier\fP field, all subclasses have a \fIvalue\fP field which is used for specifying the parameter value\&.

.SS "SoShaderParameter::SoShaderParameter (void)\fC [protected]\fP"
Constructor\&. 
.SS "SoShaderParameter::~SoShaderParameter ()\fC [protected]\fP, \fC [virtual]\fP"
Destructor\&. 
.SH "Member Function Documentation"
.PP 
.SS "\fBSoType\fP SoShaderParameter::getClassTypeId (void)\fC [static]\fP"
\fBSoSFString\fP SoShaderParameter::name
.PP
The shader parameter name\&. Used for Cg and GLSL programs\&.
.PP
\fBSoSFInt32\fP SoShaderParameter::identifier
.PP
The shader parameter identifier\&. Used for ARB shader programs\&. 
.SS "\fBSoType\fP SoShaderParameter::getTypeId (void) const\fC [virtual]\fP"

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi
.PP
.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP subclasses\&. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.
.PP
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. 
.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP * SoShaderParameter::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP
Reimplemented from \fBSoFieldContainer\fP\&.
