MovieAudio (const string &name="Blank Audio") | |
This constructor returns a null audio stream — a stream of total silence, at 8000 samples per second. More... | |
const Filename & | get_filename () const |
Returns the movie's filename. More... | |
![]() | |
TypedWritableReferenceCount (const TypedWritableReferenceCount ©) | |
virtual ReferenceCount * | as_reference_count () |
Returns the pointer cast to a ReferenceCount pointer, if it is in fact of that type. More... | |
void | operator= (const TypedWritableReferenceCount ©) |
![]() | |
TypedWritable (const TypedWritable ©) | |
virtual int | complete_pointers (TypedWritable **p_list, BamReader *manager) |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin(). More... | |
string | encode_to_bam_stream () const |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string. More... | |
bool | encode_to_bam_stream (string &data, BamWriter *writer=NULL) const |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. More... | |
virtual void | fillin (DatagramIterator &scan, BamReader *manager) |
This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. More... | |
virtual void | finalize (BamReader *manager) |
Called by the BamReader to perform any final actions needed for setting up the object after all objects have been read and all pointers have been completed. More... | |
UpdateSeq | get_bam_modified () const |
Returns the current bam_modified counter. More... | |
void | mark_bam_modified () |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |
void | operator= (const TypedWritable ©) |
virtual bool | require_fully_complete () const |
Some objects require all of their nested pointers to have been completed before the objects themselves can be completed. More... | |
virtual void | update_bam_nested (BamWriter *manager) |
Called by the BamWriter when this object has not itself been modified recently, but it should check its nested objects for updates. More... | |
virtual void | write_datagram (BamWriter *manager, Datagram &dg) |
Writes the contents of this object to the datagram for shipping out to a Bam file. More... | |
![]() | |
TypedObject (const TypedObject ©) | |
TypedObject * | as_typed_object () |
Returns the object, upcast (if necessary) to a TypedObject pointer. More... | |
const TypedObject * | as_typed_object () const |
Returns the object, upcast (if necessary) to a TypedObject pointer. More... | |
int | get_best_parent_from_Set (const std::set< int > &) const |
int | get_type_index () const |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. More... | |
bool | is_exact_type (TypeHandle handle) const |
Returns true if the current object is the indicated type exactly. More... | |
bool | is_of_type (TypeHandle handle) const |
Returns true if the current object is or derives from the indicated type. More... | |
void | operator= (const TypedObject ©) |
![]() | |
int | get_ref_count () const |
Returns the current reference count. More... | |
WeakReferenceList * | get_weak_list () const |
Returns the WeakReferenceList associated with this ReferenceCount object. More... | |
bool | has_weak_list () const |
Returns true if this particular ReferenceCount object has a WeakReferenceList created, false otherwise. More... | |
void | local_object () |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack. More... | |
void | ref () const |
Explicitly increments the reference count. More... | |
bool | test_ref_count_integrity () const |
Does some easy checks to make sure that the reference count isn't completely bogus. More... | |
bool | test_ref_count_nonzero () const |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. More... | |
virtual bool | unref () const |
Explicitly decrements the reference count. More... | |
void | weak_ref (WeakPointerToVoid *ptv) |
Adds the indicated PointerToVoid as a weak reference to this object. More... | |
void | weak_unref (WeakPointerToVoid *ptv) |
Removes the indicated PointerToVoid as a weak reference to this object. More... | |
![]() | |
Namable (const string &initial_name="") | |
Namable (const Namable ©) | |
void | clear_name () |
Resets the Namable's name to empty. More... | |
const string & | get_name () const |
bool | has_name () const |
Returns true if the Namable has a nonempty name set, false if the name is empty. More... | |
Namable & | operator= (const Namable &other) |
void | output (ostream &out) const |
Outputs the Namable. More... | |
void | set_name (const string &name) |
