Detailed Description

The SoMFEngine class is a container for engines.

This field container stores an array of pointers to engines. It takes care of the necessary functionality for handling copy, import and export operations.

Note that engine pointers stored in field instances of this type may be NULL pointers.

Member Function Documentation

void SoMFEngine::initClass (  void )  [static]

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system. Reimplemented from SoMField.

void SoMFEngine::fixCopy (  SbBool copyconnections )  [virtual]

This method is internally called after copyFrom() during scene graph copies, and should do the operations necessary for fixing up the field instance after it has gotten a new value. The default method in the SoField superclass does nothing. The application programmer should normally not need to consider this method, unless he constructs a complex field type which contains new references to container instances (i.e. nodes or engines). Overloading this method is then necessary to update the reference pointers, as they could have been duplicated during the copy operation. Reimplemented from SoField.

SbBool SoMFEngine::referencesCopy (  void )  const [virtual]

Returns TRUE if this field has references to any containers in the scene graph which are also duplicated during the copy operation. Note that this method only is valid to call during copy operations. See also the note about the relevance of the fixCopy() method for application programmers, as it is applicable on this method aswell. Reimplemented from SoField.
