Detailed Description

An animation channel that accepts a matrix each frame from some dynamic input provided by code.

This object operates in two modes: in explicit mode, the programmer should call set_value() each frame to indicate the new value; in implicit mode, the programmer should call set_value_node() to indicate the node whose transform will be copied to the joint each frame.

Member Function Documentation

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]

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 99 of file typedObject.I.

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

Returns the object, upcast (if necessary) to a TypedObject pointer.

Definition at line 110 of file typedObject.I.

void Namable::clear_name ( ) [inline, inherited]

Resets the Namable's name to empty.

Reimplemented in AsyncTask.

Definition at line 64 of file namable.I.

int AnimChannelMatrixDynamic::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 AnimGroup.

Definition at line 264 of file animChannelMatrixDynamic.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.

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.

bool TypedWritable::encode_to_bam_stream ( string &  data,
BamWriter writer = NULL 
) 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.

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.

bool ReferenceCount::unref ( ) const [inline, virtual, inherited]

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().

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.

The return value is true if the new reference count is nonzero, false if it is 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.

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().
