Member Function Documentation

const SoFieldData * SoProtoInstance::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.

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

Reimplemented from SoNode.

SoProtoInstance * SoProtoInstance::findProtoInstance (const SoNode * rootnode) [static]Given root node rootnode, return the PROTO instance, or NULL if rootnode is not a PROTO instance root node.

void SoProtoInstance::setRootNode (SoNode * root)Sets the root node for this instance.

SoNode * SoProtoInstance::getRootNode (void)Returns the instance root node.

SoProto * SoProtoInstance::getProtoDefinition (void) constReturns the PROTO definition for this instance.

SbName SoProtoInstance::getProtoName (void) constReturns the PROTO defintion name.

void SoProtoInstance::write (SoWriteAction * action) [virtual]Action method for SoWriteAction.

Writes out a node object, and any connected nodes, engines etc, if necessary.

Reimplemented from SoNode.

SbBool SoProtoInstance::readInstance (SoInput * in, unsigned short flags) [protected, virtual]This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.

const char * SoProtoInstance::getFileFormatName (void) const [protected, virtual]Returns the class name this object should be written under. Default string returned is the name of the class from the type system.

User extensions nodes and engines override this method to return the name of the extension (instead of 'UnknownNode' or 'UnknownEngine').

Reimplemented from SoBase.
