This function is called by the BamReader's factory when a new object of type RenderEffects is encountered in the Bam file. |
This represents a unique collection of RenderEffect objects that correspond to a particular renderable state.
You should not attempt to create or modify a RenderEffects object directly. Instead, call one of the make() functions to create one for you. And instead of modifying a RenderEffects object, create a new one.

void RenderEffects::adjust_transform | ( | CPT(TransformState)& | net_transform, |

The order in which the individual effects are applied is not defined, so if more than one effect applies a change to the transform on any particular node, you might get indeterminate results.

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.

Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.

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.

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

bool RenderEffects::operator< | ( | const RenderEffects & | other | ) | const |
Provides an arbitrary ordering among all unique RenderEffects, 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 RenderEffects class because all equivalent RenderEffects objects are guaranteed to share the same pointer; thus, a pointer comparison is always sufficient.

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.

bool RenderEffects::require_fully_complete | ( | ) | const [virtual] |
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).

bool RenderEffects::unref | ( | ) | const [virtual] |
This method overrides ReferenceCount::unref() to check whether the remaining reference count is entirely in the cache, and if so, it checks for and breaks a cycle in the cache involving this object.
This is designed to prevent leaks from cyclical references within the cache.
Note that this is not a virtual method, and cannot be because ReferenceCount itself declares no virtual methods (it avoids the overhead of a virtual function pointer). But this doesn't matter, because PT(TransformState) is a template class, and will call the appropriate method even though it is non-virtual.
