int RenderAttrib::compare_to | ( | const RenderAttrib & | other | ) | const [inline, inherited] |
Provides an arbitrary ordering among all unique RenderAttribs, so we can store the essentially different ones in a big set and throw away the rest.
This method is not needed outside of the RenderAttrib class because all equivalent RenderAttrib objects are guaranteed to share the same pointer; thus, a pointer comparison is always sufficient.

int CullBinAttrib::compare_to_impl | ( | const RenderAttrib * | other | ) | const [protected, virtual] |
Intended to be overridden by derived CullBinAttrib types to return a unique number indicating whether this CullBinAttrib is equivalent to the other one.
This should return 0 if the two CullBinAttrib objects are equivalent, a number less than zero if this one should be sorted before the other one, and a number greater than zero otherwise.
This will only be called with two CullBinAttrib objects whose get_type() functions return the same.

int TypedWritable::complete_pointers | ( | TypedWritable ** | p_list, |
BamReader * | manager | ||
) | [virtual, inherited] |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

bool RenderAttrib::cull_callback | ( | CullTraverser * | trav, |

If has_cull_callback() returns true, this function will be called during the cull traversal to perform any additional operations that should be performed at cull time.
This is called each time the RenderAttrib is discovered applied to a Geom in the traversal. It should return true if the Geom is visible, false if it should be omitted.

bool TypedWritable::decode_raw_from_bam_stream | ( | TypedWritable *& | ptr, |
ReferenceCount *& | ref_ptr, | ||
const string & | data, | ||
BamReader * | reader = NULL |
||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

string TypedWritable::encode_to_bam_stream | ( | ) | const [inline, inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.

It actually achieves this by setting a large positive value in the reference count field.

bool RenderAttrib::lower_attrib_can_override | ( | ) | const [virtual, inherited] |
Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact.
This should return false if a RenderAttrib on a higher node will compose into a RenderAttrib on a lower node that has a higher override value, or true if the lower RenderAttrib will completely replace the state.
The default behavior is false: normally, a RenderAttrib in the graph cannot completely override a RenderAttrib above it, regardless of its override value--instead, the two attribs are composed. But for some kinds of RenderAttribs, it is useful to allow this kind of override.
This method only handles the one special case of a lower RenderAttrib with a higher override value. If the higher RenderAttrib has a higher override value, it always completely overrides. And if both RenderAttribs have the same override value, they are always composed.

Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

int RenderAttrib::register_slot | ( | TypeHandle | type_handle, |

Adds the indicated TypeHandle to the registry, if it is not there already, and returns a unique slot number.

Tells the BamReader how to create objects of type CullBinAttrib.

bool TypedWritable::require_fully_complete | ( | ) | const [virtual, inherited] |
Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).
Reimplemented in GeomVertexData, ClipPlaneAttrib, and RenderEffects.

bool ReferenceCount::test_ref_count_integrity | ( | ) | const [inline, inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.
Returns true if ok, false otherwise.

bool ReferenceCount::test_ref_count_nonzero | ( | ) | const [inline, inherited] |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

bool RenderAttrib::unref | ( | ) | const [virtual, inherited] |
This method overrides ReferenceCount::unref() to clear the pointer from the global object pool when its reference count goes to zero.

void TypedWritable::update_bam_nested | ( | BamWriter * | manager | ) | [virtual, inherited] |
Called by the BamWriter when this object has not itself been modified recently, but it should check its nested objects for updates.
Reimplemented in CFDoCullCommand, and PandaNode.

bool RenderAttrib::validate_attribs | ( | ) | [static, inherited] |
Ensures that the cache is still stored in sorted order.
Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderAttrib objects).

Adds the indicated PointerToVoid as a weak reference to this object.

void ReferenceCount::weak_unref | ( | WeakPointerToVoid * | ptv | ) | [inline, inherited] |
Removes the indicated PointerToVoid as a weak reference to this object.
It must have previously been added via a call to weak_ref().
