VectorUchar | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. More... | |
bool | encodeToBamStream (VectorUchar data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. More... | |
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... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |

int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. 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... | |

int | getRefCount () |
Returns the current reference count. More... | |

Explicitly increments the reference count. More... | |
bool | testRefCountIntegrity () |

Returns a sequence number that's guaranteed to change at least when any VertexSliders in the table change. More... | |

![]() | |
int | ref_count |
The current reference count. More... | |
Stores the total set of VertexSliders that the vertices in a particular GeomVertexData object might depend on.
This is similar to a TransformTable, but it stores VertexSliders instead of VertexTransforms, and it stores them by name instead of by index number. Also, it is only used when animating vertices on the CPU, since GPU's don't support morphs at this point in time.
__init__ | ( | ) |
__init__ | ( | const SliderTable | copy | ) |
int addSlider | ( | const VertexSlider | slider, |
const SparseArray | rows | ||
) |
Adds a new slider to the table, and returns the index number of the new slider.
Only valid for unregistered tables.
const SparseArray findSliders | ( | const InternalName | name | ) |
Returns a list of slider indices that represent the list of sliders with the indicated name, or an empty SparseArray if no slider in the table has that name.
|
static |
Returns a sequence number that's guaranteed to change at least when any VertexSliders 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 VertexSlider changes.)
int getNumSliders | ( | ) |
Returns the number of sliders in the table.
const VertexSlider getSlider | ( | int | n | ) |
Returns the nth slider in the table.
const SparseArray getSliderRows | ( | int | n | ) |
Returns the set of rows (vertices) governed by the nth slider in the table.
list getSliders | ( | ) |
bool hasSlider | ( | const InternalName | name | ) |
Returns true if the table has at least one slider by the indicated name, false otherwise.
bool isEmpty | ( | ) |
Returns true if the table has no sliders, false if it has at least one.
bool isRegistered | ( | ) |
Returns true if this table has been registered.
Once it has been registered, the set of sliders in a SliderTable may not be further modified; but it must be registered before it can be assigned to a Geom.
SliderTable operator= | ( | const SliderTable | copy | ) |
|
static |
Registers a SliderTable for use.
This is similar to GeomVertexFormat::register_format(). Once registered, a SliderTable may no longer be modified (although the individual VertexSlider objects may modify their reported sliders).
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.
removeSlider | ( | int | n | ) |
Removes the nth slider.
Only valid for unregistered tables.
setSlider | ( | int | n, |
const VertexSlider | slider | ||
) |
Replaces the nth slider.
Only valid for unregistered tables.
setSliderRows | ( | int | n, |
const SparseArray | rows | ||
) |
Replaces the rows affected by the nth slider.
Only valid for unregistered tables.
write | ( | Ostream | out | ) |
UpdateSeq modified |
Returns a sequence number that's guaranteed to change at least when any VertexSliders 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 VertexSlider changes.)
