static TypedWritablemake_texcoord_from_bam (const FactoryParams &params)
 This is a temporary method; it exists only to support old bam files (4.11 through 4.17) generated before we renamed this class from TexCoordName to InternalName.

Detailed Description

Encodes a string name in a hash table, mapping it to a pointer.

This is used to tokenify names so they may be used efficiently in low-level Panda structures, for instance to differentiate the multiple sets of texture coordinates that might be stored on a Geom.

InternalNames are hierarchical, with the '.' used by convention as a separator character. You can construct a single InternalName as a composition of one or more other names, or by giving it a source string directly.

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.

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

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

Returns the number of pointers processed.

This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

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,
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.

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 TypedWritable::fillin ( DatagramIterator scan,

It is also called directly by the BamReader to re-read the data for an object that has been placed on the stream for an update.

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.

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.
