 Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
 
vector_uchar encode_to_bam_stream () const
 Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object.
 
bool encode_to_bam_stream (vector_uchar &data, BamWriter *writer=nullptr) const
 Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string.
 
virtual void finalize (BamReader *manager)
 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.
 
virtual TypeHandle force_init_type ()
 
UpdateSeq get_bam_modified () const
 Returns the current bam_modified counter.
 
void mark_bam_modified ()
 Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.
 
void operator= (const TypedWritable &copy)
 
virtual bool require_fully_complete () const
 Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
 
virtual void update_bam_nested (BamWriter *manager)
 Called by the BamWriter when this object has not itself been modified recently, but it should check its nested objects for updates.

int get_best_parent_from_Set (const std::set< int > &) const
 
int get_type_index () const
 Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
 
bool is_exact_type (TypeHandle handle) const
 Returns true if the current object is the indicated type exactly.
 
bool is_of_type (TypeHandle handle) const

Detailed Description

This represents a particular position of a texture within a PaletteImage.

There is only one of these per TexturePlacement, but it exists as a separate structure so the TexturePlacement can easily consider repositioning the texture.
