// Class : InternalName
|
|
// Description : Encodes a string name in a hash table, mapping it to
|
|
// a pointer. This is used to tokenify names so they
|
|
// may be used efficiently in low-level Panda
|
|
// structures, for instance to differentiate the
|
|
// multiple sets of texture coordinates that might be
|
|
// stored on a Geom.
|
|
//
|
|
// InternalNames are hierarchical, with the '.' used by
|
|
// convention as a separator character. You can
|
|
// construct a single InternalName as a composition of
|
|
// one or more other names, or by giving it a source
|
|
// string directly.
