|
|
// CLASS DESCRIPTION (MFnPluginData)
|
|
//
|
|
// diagram if the class is visual in nature.
|
|
// All user defined data that is to be passed between nodes in the dependency
|
|
// graph must be derived from MPxData. The use of this class is closely
|
|
// linked to the use of MPxDataCreator, MFnPluginData, MDataHandle, and
|
|
// MTypeId.
|
|
//
|
|
// In order to use user defined data, one must first create an instance of
|
|
// the
|
|
// MTypeId class that is initialized with a unique id tag. Then create a new
|
|
// class derived from MPxData to hold the user-defined data, As well as a
|
|
// helper class derived from MPxDataCreator that can create instances of the
|
|
// new derived type.
|
|
//
|
|
// For data of this type that needs to be passed into a plug, one would get
|
|
// an
|
|
// MDataHandle for the attribute that uses the type. This would result in a
|
|
// call to the MPxDataCreator helper class that would create an instance of
|
|
// the type inside the MDataHandle. The MDataHandle::data method can then be
|
|
// used to get an get an MObject for the user defined data and this should be
|
|
// used to initialize an instance of MFnPluginData. Then the
|
|
// MFnPluginData::data method can be used to get an MPxData pointer, which
|
|
// can
|
|
// be safely cast to a pointer of the user defined type. The data can be
|
|
// updated through this pointer, after which the MDataHandle::setClean method
|
|
// is used to complete the operation.
|
|
//
|
|
// To receive data of this type from a plug, an MDataHandle for the attribute
|
|
// that uses the new data type is created. The MDataHandle::type method
|
|
// should be used to ascertain that it contains kPlugin data. Then the
|
|
// MDataHandle::data method is used to get an MObject for the user defined
|
|
// data and this should be used to initialize an instance of MFnPluginData.
|
|
// The MFnPluginData::typeId method can be used to ascertain that the data is
|
|
// in fact of the user defined type. Then the MFnPluginData::data method can
|
|
// be used to get an MPxData pointer, which can be safely cast to a pointer
|
|
// to
|
|
// the user defined type.
