Public Member Functions

int compareTimestamp (const MovieVideoCursor::Buffer other)
 Used to sort different buffers to ensure they correspond to the same source frame, particularly important when synchronizing the different pages of a multi-page texture. More...
 
double getTimestamp ()
 Returns the nearest timestamp value of this particular buffer. Ideally, MovieVideoCursor::set_time() for this timestamp would return this buffer again. This need be defined only if compare_timestamp() is also defined. More...
 
- Public Member Functions inherited from TypedObject
TypeHandle getType ()
 Derived classes should override this function to return get_class_type(). More...
 
int getTypeIndex ()
 Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More...
 
bool isExactType (TypeHandle handle)
 Returns true if the current object is the indicated type exactly. More...
 
bool isOfType (TypeHandle handle)
 Returns true if the current object is or derives from the indicated type. More...
 
- Public Member Functions inherited from ReferenceCount
int getRefCount ()
 Returns the current reference count. More...
 
 ref ()
 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. More...
 
bool testRefCountIntegrity ()
 Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
 
bool testRefCountNonzero ()
 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
 
bool unref ()
 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(). More...

◆ compareTimestamp()

int compareTimestamp ( const MovieVideoCursor::Buffer  other)

Used to sort different buffers to ensure they correspond to the same source frame, particularly important when synchronizing the different pages of a multi-page texture.

Returns 0 if the two buffers are of the same frame, <0 if this one comes earlier than the other one, and >0 if the other one comes earlier.

◆ getClassType()

◆ getTimestamp()

double getTimestamp ( )

Returns the nearest timestamp value of this particular buffer. Ideally, MovieVideoCursor::set_time() for this timestamp would return this buffer again. This need be defined only if compare_timestamp() is also defined.
