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.

Similar to bind_hierarchy, but does not actually perform any binding.

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 TypedWritable::mark_bam_modified | ( | ) | [inline, inherited] |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.
This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients.

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 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).

void PartGroup::sort_descendants | ( | ) |
Sorts the children nodes at each level of the hierarchy into alphabetical order.
This should be done after creating the hierarchy, to guarantee that the correct names will match up together when the AnimBundle is later bound to a PlayerRoot.

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.
