class | VertexTransform |
Stores the total set of VertexTransforms that the vertices in a particular GeomVertexData object might depend on.
This structure is used for a GeomVertexData set up to compute its dynamic vertices on the graphics card. See TransformBlendTable for one set up to compute its dynamic vertices on the CPU.
Definition at line 42 of file transformTable.h.
int TransformTable::add_transform | ( | const VertexTransform * | transform | ) |
Adds a new transform to the table and returns the index number of the new transform.
Only valid for unregistered tables.
This does not automatically uniquify the pointer; if the transform is already present in the table, it will be added twice.
Definition at line 105 of file transformTable.cxx.
ReferenceCount * TypedWritableReferenceCount::as_reference_count | ( | ) | [virtual, inherited] |

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.

bool TypedWritable::encode_to_bam_stream | ( | string & | data, |

) | const [inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string.
Returns true on success, false 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.

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.

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.

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.
