# SliderTable

from pandac.PandaModules import SliderTable

Class : SliderTable
Description : 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.

addSlider int SliderTable::add_slider(VertexSlider const *slider, SparseArray const &rows); Description: Adds a new slider to the table, and returns the index number of the new slider. Only valid for unregistered tables.

findSliders SparseArray const &SliderTable::find_sliders(InternalName const *name) const; Description: 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.

getClassType static TypeHandle SliderTable::get_class_type(void); Undocumented function.

getModified UpdateSeq SliderTable::get_modified(Thread *current_thread) const; Description: 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.)

getNumSliders int SliderTable::get_num_sliders(void) const; Description: Returns the number of sliders in the table.

getSlider VertexSlider const *SliderTable::get_slider(int n) const; Description: Returns the nth slider in the table.

getSliderRows SparseArray const &SliderTable::get_slider_rows(int n) const; Description: Returns the set of rows (vertices) governed by the nth slider in the table.

hasSlider bool SliderTable::has_slider(InternalName const *name) const; Description: Returns true if the table has at least one slider by the indicated name, false otherwise.

isEmpty bool SliderTable::is_empty(void) const; Description: Returns true if the table has no sliders, false if it has at least one.

isRegistered bool SliderTable::is_registered(void) const; Filename: sliderTable.I Created by: drose (28Mar05) PANDA 3D SOFTWARE Copyright (c) 2001 - 2004, Disney Enterprises, Inc.

To contact the maintainers of this program write to panda3d-general@lists.sourceforge.net . Description: 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.

operator = void SliderTable::operator =(SliderTable const &copy); Description:

registerTable static ConstPointerTo< SliderTable > SliderTable::register_table(SliderTable const *table); Description: 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 void SliderTable::remove_slider(int n); Description: Removes the nth slider. Only valid for unregistered tables.

setSlider void SliderTable::set_slider(int n, VertexSlider const *slider); Description: Replaces the nth slider. Only valid for unregistered tables.

setSliderRows void SliderTable::set_slider_rows(int n, SparseArray const &rows); Description: Replaces the rows affected by the nth slider. Only valid for unregistered tables.

write void SliderTable::write(ostream &out) const; Description:

getClassType static TypeHandle TypedWritableReferenceCount::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedWritable::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedObject::get_class_type(void); Undocumented function.

getType virtual TypeHandle TypedObject::get_type(void) const = 0; Derived classes should override this function to return get_class_type().

getTypeIndex int TypedObject::get_type_index(void) const; Description: 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().

isExactType bool TypedObject::is_exact_type(TypeHandle handle) const; Description: Returns true if the current object is the indicated type exactly.

isOfType bool TypedObject::is_of_type(TypeHandle handle) const; Description: Returns true if the current object is or derives from the indicated type.

getClassType static TypeHandle ReferenceCount::get_class_type(void); Undocumented function.

getRefCount int ReferenceCount::get_ref_count(void) const; Description: Returns the current reference count.

ref void ReferenceCount::ref(void) const; Description: 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. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

testRefCountIntegrity bool ReferenceCount::test_ref_count_integrity(void) const; Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

testRefCountNonzero bool ReferenceCount::test_ref_count_nonzero(void) const; Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref bool ReferenceCount::unref(void) const; Description: 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; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). 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. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is true if the new reference count is nonzero, false if it is zero.
