NAME

       SoInt32Element -

       The SoInt32Element class is the base class for elements that simply store a 32-bit integer.

       This is the superclass of elements where the new element data replaces the old data, and where the data
       the element stores is a simple 32-bit integer value.

Detailed Description

       The SoInt32Element class is the base class for elements that simply store a 32-bit integer.

       This is the superclass of elements where the new element data replaces the old data, and where the data
       the element stores is a simple 32-bit integer value.

       This element is like a convenient light-weight version of the SoReplacedElement. It differs from the
       SoReplacedElement in that the set() and get() methods are already implemented, since it is known that
       subclasses will still contain just a single 32-bit integer value.

Member Function Documentation

   SbBool SoInt32Element::matches (const SoElement *element) const [virtual]
       This function returns TRUE is the element matches another element (of the same class), with respect to
       cache validity.

       If the application programmer's extension element has a matches() function, it should also have a
       copyMatchInfo() function.

       Implements SoElement.

   SoElement * SoInt32Element::copyMatchInfo (void) const [virtual]
       This function creates a copy of the element that contains enough information to enable the matches()
       function to work.

       Used to help with scenegraph traversal caching operations.

       Implements SoElement.

   void SoInt32Element::print (FILE *file) const [virtual]
       This function is for printing element information, and is used mostly for debugging purposes.

       Reimplemented from SoElement.

   void SoInt32Element::set (const intindex, SoState *conststate, const int32_tvalue) [static]
       FIXME: write doc.

Member Data Documentation

   SoInt32Element::data [protected]
       The 32-bit integer value of the element.
