Detailed 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.

Member Function Documentation

void InternalName::finalize ( BamReader * manager ) [virtual]

Called by the BamReader to perform any final actions needed for setting up the object after all objects have been read and all pointers have been completed.

Reimplemented from TypedWritable.

Definition at line 288 of file internalName.cxx.

References ReferenceCount::get_ref_count(), and unref().

int InternalName::find_ancestor ( const string & basename ) const

Returns the index of the ancestor with the indicated basename, or -1 if no ancestor has that basename.

Returns 0 if this name has the basename.

This index value may be passed to get_ancestor() or get_net_basename() to retrieve more information about the indicated name.

Definition at line 169 of file internalName.cxx.

References ReferenceCount::test_ref_count_integrity().

Referenced by NodePath::find_all_texcoords().

const InternalName * InternalName::get_ancestor ( int n ) const

Returns the ancestor with the indicated index number.

0 is this name itself, 1 is the name's parent, 2 is the parent's parent, and so on. If there are not enough ancestors, returns the root InternalName.

Definition at line 194 of file internalName.cxx.

References ReferenceCount::test_ref_count_integrity().

const string & InternalName::get_basename ( ) const [inline]

Return the name represented by just this particular InternalName object, ignoring its parents names.

This is everything after the rightmost dot.

Definition at line 54 of file internalName.I.

string InternalName::get_name ( ) const

Returns the complete name represented by the InternalName and all of its parents.

Definition at line 145 of file internalName.cxx.

Referenced by GraphicsStateGuardian::fetch_specified_part(), NodePath::find_all_vertex_columns(), Texture::load_related(), TextureStage::write(), and write_datagram().

string InternalName::get_net_basename ( int n ) const

Returns the basename of this name prefixed by the indicated number of ancestors.

0 is this name's basename, 1 is parent.basename, 2 is grandparent.parent.basename, and so on.

Definition at line 235 of file internalName.cxx.

Referenced by NodePath::find_all_texcoords().

InternalName * InternalName::get_parent ( ) const [inline]

Return the parent of this InternalName.

All names have a parent, except the root name.

Definition at line 42 of file internalName.I.

const InternalName * InternalName::get_top ( ) const

Returns the oldest ancestor in the InternalName's chain, not counting the root.

This will be the first name in the string, e.g. "texcoord.foo.bar" will return the InternalName "texcoord".

TypedWritable * InternalName::make_from_bam ( const FactoryParams & params ) [static, protected]

This function is called by the BamReader's factory when a new object of type InternalName is encountered in the Bam file.

It should create the InternalName and extract its information from the file.

TypedWritable * InternalName::make_texcoord_from_bam ( const FactoryParams & params ) [static, protected]

This is a temporary method; it exists only to support old bam files (4.11 through 4.17) generated before we renamed this class from TexCoordName to InternalName.

void InternalName::register_with_read_factory ( ) [static]

Factory method to generate a InternalName object.

Definition at line 275 of file internalName.cxx.

References BamReader::get_factory(), make_from_bam(), make_texcoord_from_bam(), and Factory< Type >::register_factory().

bool InternalName::unref ( ) const [virtual]

This method overrides ReferenceCount::unref() to clear the pointer from its parent's table when its reference count goes to zero.

Reimplemented from ReferenceCount.
