bool RenderAttrib::always_reissue ( ) const [inline, inherited]

Returns true if the RenderAttrib should be reissued to the GSG with every state change, even if it is the same pointer as it was before; or false for the normal case, to reissue only when the RenderAttrib pointer changes.

Definition at line 62 of file renderAttrib.I.

ReferenceCount * TypedWritableReferenceCount::as_reference_count ( ) [virtual, inherited]

Returns the pointer cast to a ReferenceCount pointer, if it is in fact of that type.

Reimplemented from TypedWritable.

Definition at line 26 of file typedWritableReferenceCount.cxx.

TypedObject * TypedObject::as_typed_object ( ) [inline, inherited]

Definition at line 99 of file typedObject.I.

const TypedObject * TypedObject::as_typed_object ( ) const [inline, inherited]

Definition at line 110 of file typedObject.I.

TypedWritable * RenderAttrib::change_this ( TypedWritable old_ptr,
BamReader manager 
) [static, inherited]

Called immediately after complete_pointers(), this gives the object a chance to adjust its own pointer if desired.

Most objects don't change pointers after completion, but some need to.

Once this function has been called, the old pointer will no longer be accessed.

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.

Definition at line 79 of file renderAttrib.I.

References RenderAttrib::compare_to_impl(), and TypeHandle::get_index().

int TexGenAttrib::compare_to_impl ( const RenderAttrib other) const [protected, virtual]

Intended to be overridden by derived TexGenAttrib types to return a unique number indicating whether this TexGenAttrib is equivalent to the other one.

This should return 0 if the two TexGenAttrib 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 TexGenAttrib objects whose get_type() functions return the same.

Reimplemented from RenderAttrib.

Definition at line 374 of file texGenAttrib.cxx.

int TexGenAttrib::complete_pointers ( TypedWritable **  p_list,
BamReader manager 
) [virtual]

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

Definition at line 642 of file texGenAttrib.cxx.

bool RenderAttrib::cull_callback ( CullTraverser trav,
const CullTraverserData data 
) const [virtual, inherited]

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.

Reimplemented in TextureAttrib.

Definition at line 134 of file renderAttrib.cxx.

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.

Returns empty string on failure.

This is a convenience method particularly useful for cases when you are only serializing a single object. If you have many objects to process, it is more efficient to use the same BamWriter to serialize all of them together.

Definition at line 86 of file typedWritable.I.

bool TypedWritable::encode_to_bam_stream ( string &  data,

void RenderAttrib::list_attribs ( ostream &  out) [static, inherited]

This can be quite a lot of output if the cache is large, so be prepared.

Definition at line 209 of file renderAttrib.cxx.

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. 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.

void ReferenceCount::ref ( ) const [inline, inherited]

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,
int  sort,
RenderAttribRegistry::MakeDefaultFunc *  make_default_func 
) [inline, static, inherited]

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

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]
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.

Returns true if ok, false otherwise.

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.

Reimplemented from ReferenceCount.

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.

Definition at line 77 of file typedWritable.cxx.

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).

void ReferenceCount::weak_ref ( WeakPointerToVoid ptv) [inline, inherited]

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().
