 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...

 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.

 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...

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...

 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...

Detailed Description

Stores the total set of VertexTransforms that the vertices in a particular GeomVertexData object might depend on.

This structure is used for a GeomVertexData set up to compute its dynamic vertices on the graphics card. See TransformBlendTable for one set up to compute its dynamic vertices on the CPU.

Member Function Documentation

◆ __init__() [1/2]

__init__ ( )

◆ __init__() [2/2]

__init__ ( const TransformTable  copy)

◆ addTransform()

int addTransform ( const VertexTransform  transform)

Adds a new transform to the table and returns the index number of the new transform. Only valid for unregistered tables.

This does not automatically uniquify the pointer; if the transform is already present in the table, it will be added twice.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getModified()

UpdateSeq getModified ( Thread  current_thread)

Returns a sequence number that's guaranteed to change at least when any VertexTransforms in the table change. (However, this is only true for a registered table. An unregistered table may or may not reflect an update here when a VertexTransform changes.)

◆ getNumTransforms()

int getNumTransforms ( )

Returns the number of transforms in the table.

◆ getTransform()

const VertexTransform getTransform ( int  n)

Returns the nth transform in the table.

◆ getTransforms()

list getTransforms ( )

◆ isRegistered()

bool isRegistered ( )

Returns true if this table has been registered. Once it has been registered, the set of transforms in a TransformTable may not be further modified; but it must be registered before it can be assigned to a Geom.

◆ operator=()

TransformTable operator= ( const TransformTable  copy)

◆ registerTable()

static const TransformTable registerTable ( const TransformTable  table)
static

Registers a TransformTable for use. This is similar to GeomVertexFormat::register_format(). Once registered, a TransformTable may no longer be modified (although the individual VertexTransform objects may modify their reported transforms).

This must be called before a table may be used in a Geom. After this call, you should discard the original pointer you passed in (which may or may not now be invalid) and let its reference count decrement normally; you should use only the returned value from this point on.

◆ removeTransform()

removeTransform ( int  n)

Removes the nth transform. Only valid for unregistered tables.

◆ setTransform()

setTransform ( int  n,
const VertexTransform  transform 
)

Replaces the nth transform. Only valid for unregistered tables.

◆ write()

write ( Ostream  out)
