Public Member Functions

bool getTight ()
 Returns true if the "tight" flag was set, meaning the effect should compute and draw the tight bounding-box of the node's vertices every frame. More...
 
- Public Member Functions inherited from RenderEffect
int compareTo (const RenderEffect other)
 Provides an arbitrary ordering among all unique RenderEffects, so we can store the essentially different ones in a big set and throw away the rest. More...

object __reduce__ ()
 
object __reduce_persist__ (object pickler)
 
str encodeToBamStream ()
 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. More...
 
bool encodeToBamStream (String data, BamWriter writer)
 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. More...
 
UpdateSeq getBamModified ()
 Returns the current bam_modified counter. This counter is normally incremented automatically whenever the object is modified. More...
 
 markBamModified ()
 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. 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...

 Lists all of the RenderEffects in the cache to the output stream, one per line. This can be quite a lot of output if the cache is large, so be prepared. More...

 Ensures that the cache is still stored in sorted order. Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderEffect objects). More...
