NAME¶

SoShaderParameter -

SYNOPSIS¶

#include <Inventor/nodes/SoShaderParameter.h> Inherits SoNode. Inherited by SoUniformShaderParameter.

Public Member Functions¶

virtual SoType getTypeId (void) const Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Static Public Member Functions¶

static SoType getClassTypeId (void) static void initClass () Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Public Attributes¶

SoSFString name SoSFInt32 identifier

Protected Member Functions¶

virtual const SoFieldData * getFieldData (void) const SoShaderParameter () virtual ~SoShaderParameter ()

Static Protected Member Functions¶

static const SoFieldData ** getFieldDataPtr (void)

Additional Inherited Members¶

Detailed Description¶

The SoShaderParameter class is the base class for all shader parameter classes. In addition to the name and identifier field, all subclasses have a value field which is used for specifying the parameter value.

Constructor & Destructor Documentation¶

SoShaderParameter::SoShaderParameter (void) [protected]¶

Constructor.

SoShaderParameter::~SoShaderParameter () [protected], [virtual]¶

Destructor.

Member Function Documentation¶

SoType SoShaderParameter::getClassTypeId (void) [static]¶

SoSFString SoShaderParameter::name The shader parameter name. Used for Cg and GLSL programs. SoSFInt32 SoShaderParameter::identifier The shader parameter identifier. Used for ARB shader programs. Reimplemented from SoNode.

SoType SoShaderParameter::getTypeId (void) const [virtual]¶

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting. Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all 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 Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups. Implements SoBase.

const SoFieldData ** SoShaderParameter::getFieldDataPtr (void) [static], [protected]¶

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoNode.

const SoFieldData * SoShaderParameter::getFieldData (void) const [protected], [virtual]¶

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from SoFieldContainer.
