static AttribNodeRegistry * | get_global_ptr () |
This global object records NodePaths that are referenced by scene graph attribs, such as ClipPlaneAttribs and LightAttribs.
Its primary purpose is to unify attribs that are loaded in from bam files. Attrib nodes are identified by name and type; when a bam file that contains references to some attrib nodes is loaded, those nodes are first looked up here in the AttribNodeRegistry. If there is a match (by name and node type), the identified node is used instead of the node referenced within the bam file itself.
Definition at line 38 of file attribNodeRegistry.h.
void AttribNodeRegistry::add_node | ( | const NodePath & | attrib_node | ) |
Adds the indicated NodePath to the registry.
The name and type of the node are noted at the time of this call; if the name changes later, it will not update the registry index.
The NodePath must reference some kind of an attribute node, such as a LightNode or a PlaneNode. When bam files that reference an attribute node of the same type and the same name are loaded, they will quietly be redirected to reference this NodePath.
If there is already a node matching the indicated name and type, it will be replaced.

string AttribNodeRegistry::get_node_name | ( | int | n | ) | const |
Returns the name of the nth node, as recorded in the registry.
This will be the node name as it was at the time the node was recorded; if the node has changed names since then, this will still return the original name.

NodePath AttribNodeRegistry::lookup_node | ( | const NodePath & | orig_node | ) | const |
Looks up the indicated NodePath in the registry.
If there is a node already in the registry with the matching name and type, returns that NodePath instead; otherwise, returns the original NodePath.

References ordered_vector< Key, Compare >::end(), and NodePath::is_empty().
bool AttribNodeRegistry::remove_node | ( | const NodePath & | attrib_node | ) |
Removes the indicated NodePath from the registry.
The name of the node must not have changed since the matching call to add_node(), or it will not be successfully removed.
Returns true if the NodePath is found and removed, false if it is not found (for instance, because the name has changed).
