Returns a RenderState with no attributes set.
Returns a new RenderState object that represents the same as the source state, with the indicated RenderAttrib removed.
Returns true if an attrib of the indicated type is present, false otherwise. Returns true if an attrib of the indicated type is present, false otherwise. Looks for a RenderAttrib of the indicated type in the state, and returns it if it is found, or NULL if it is not. Returns the RenderAttrib with the indicated slot index, or NULL if there is no such RenderAttrib in the state. Returns the RenderAttrib with the indicated slot index, or the default attrib for that slot if there is no such RenderAttrib in the state. Looks for a RenderAttrib of the indicated type in the state, and returns its override value if it is found, or 0 if it is not. Looks for a RenderAttrib of the indicated type in the state, and returns its override value if it is found, or 0 if it is not. Returns the pointer to the unique RenderState in the cache that is equivalent to this one. This may be the same pointer as this object, or it may be a different pointer; but it will be an equivalent object, and it will be a shared pointer. This may be called from time to time to improve cache benefits. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Returns the number of entries in the composition cache for this RenderState. This is the number of other RenderStates whose composition with this one has been cached. This number is not useful for any practical reason other than performance analysis. Returns the number of entries in the invert_composition cache for this RenderState. This is similar to the composition cache, but it records cache entries for the invert_compose() operation. See get_composition_cache_num_entries(). Returns the number of slots in the composition cache for this RenderState. You may use this as an upper bound when walking through all of the composition cache results via get_composition_cache_source() or result().
This has no practical value other than for examining the cache for performance analysis. Returns the source RenderState of the nth element in the composition cache. Returns NULL if there doesn't happen to be an entry in the nth element. See get_composition_cache_result().
This has no practical value other than for examining the cache for performance analysis. Returns the result RenderState of the nth element in the composition cache. Returns NULL if there doesn't happen to be an entry in the nth element.
In general, a->compose(a->get_composition_cache_source(n)) == a->get_composition_cache_result(n).

In general, a->invert_compose(a->get_invert_composition_cache_source(n)) == a->get_invert_composition_cache_result(n).
This has no practical value other than for examining the cache for performance analysis. Returns the draw order indicated by the CullBinAttrib, if any, associated by this state (or 0 if there is no CullBinAttrib). See get_bin_index(). Returns the bin index indicated by the CullBinAttrib, if any, associated by this state (or the default bin index if there is no CullBinAttrib). This function is provided as an optimization for determining this at render time. This function should only be called from the destructor; it indicates that this RenderState object is beginning destruction. It is only used as a sanity check, and is only meaningful when NDEBUG is not defined.
