Detailed 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.

Definition at line 37 of file sliderTable.h.

Member Function Documentation

◆ add_slider()

size_t SliderTable::add_slider	(	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.

Definition at line 109 of file sliderTable.cxx.

◆ complete_pointers()

int SliderTable::complete_pointers	(	TypedWritable **	p_list,
		BamReader *	manager
	)

virtual

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

Definition at line 198 of file sliderTable.cxx.

◆ find_sliders()

const SparseArray & SliderTable::find_sliders ( const InternalName * name ) const

inline

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.

Definition at line 81 of file sliderTable.I.

Referenced by has_slider().

◆ get_slider_rows()

const SparseArray & SliderTable::get_slider_rows ( size_t n ) const

inline

Returns the set of rows (vertices) governed by the nth slider in the table.

Definition at line 70 of file sliderTable.I.

◆ has_slider()

bool SliderTable::has_slider ( const InternalName * name ) const

inline

Returns true if the table has at least one slider by the indicated name, false otherwise.

Definition at line 95 of file sliderTable.I.

References find_sliders().

◆ is_empty()

bool SliderTable::is_empty ( ) const

inline

Returns true if the table has no sliders, false if it has at least one.

Definition at line 103 of file sliderTable.I.

◆ is_registered()

bool SliderTable::is_registered ( ) const

inline

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.

Definition at line 20 of file sliderTable.I.

◆ register_with_read_factory()

void SliderTable::register_with_read_factory ( )

static

Tells the BamReader how to create objects of type SliderTable.

Definition at line 170 of file sliderTable.cxx.

References BamReader::get_factory(), and Factory< Type >::register_factory().

◆ remove_slider()

void SliderTable::remove_slider ( size_t n )

Removes the nth slider.

Only valid for unregistered tables.

Definition at line 96 of file sliderTable.cxx.

◆ set_slider()

void SliderTable::set_slider	(	size_t	n,
		const VertexSlider *	slider
	)

Replaces the nth slider.

Only valid for unregistered tables.

Definition at line 66 of file sliderTable.cxx.

◆ set_slider_rows()

void SliderTable::set_slider_rows	(	size_t	n,
		const SparseArray &	rows
	)

Replaces the rows affected by the nth slider.

Only valid for unregistered tables.

Definition at line 83 of file sliderTable.cxx.

◆ write_datagram()

void SliderTable::write_datagram	(	BamWriter *	manager,
		Datagram &	dg
	)

virtual

Writes the contents of this object to the datagram for shipping out to a Bam file.

Reimplemented from TypedWritable.

References Datagram::add_uint16(), BamWriter::write_cdata(), TypedWritable::write_datagram(), and BamWriter::write_pointer().

Member Data Documentation

◆ get_modified

UpdateSeq SliderTable::get_modified

inline

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.)

Definition at line 56 of file sliderTable.h.

◆ get_num_sliders

size_t SliderTable::get_num_sliders

inline

Returns the number of sliders in the table.

Definition at line 49 of file sliderTable.h.

◆ get_slider

const VertexSlider * SliderTable::get_slider

inline

Returns the nth slider in the table.

Definition at line 49 of file sliderTable.h.
