Detailed Description

object provides direct access to cells in vtkCellArray and type information

This class is a supplemental object to vtkCellArray to allow random access into cells as well as representing cell type information. The "location" field is the location in the vtkCellArray list in terms of an integer offset. An integer offset was used instead of a pointer for easy storage and inter-process communication. The type information is defined in the file vtkCellType.h.

Warning:: Sometimes this class is used to pass type information independent of the random access (i.e., location) information. For example, see vtkDataSet::GetCellTypes(). If you use the class in this way, you can use a location value of -1.

Member Function Documentation

static vtkCellTypes* vtkCellTypes::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkCellTypes::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkCellTypes::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkCellTypes* vtkCellTypes::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkCellTypes::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkObject.

vtkCellTypes* vtkCellTypes::NewInstance ( ) const

Reimplemented from vtkObject.

void vtkCellTypes::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

int vtkCellTypes::Allocate	(	int	sz = `512`,
		int	ext = `1000`
	)

Allocate memory for this array. Delete old storage only if necessary.

void vtkCellTypes::InsertCell	(	int	id,
		unsigned char	type,
		int	loc
	)

Add a cell at specified id.

int vtkCellTypes::InsertNextCell	(	unsigned char	type,
		int	loc
	)

Add a cell to the object in the next available slot.

void vtkCellTypes::SetCellTypes	(	int	ncells,
		vtkUnsignedCharArray *	cellTypes,
		vtkIntArray *	cellLocations
	)

Specify a group of cell types.

int vtkCellTypes::GetCellLocation ( int cellId ) [inline]

Return the location of the cell in the associated vtkCellArray.

Definition at line 71 of file vtkCellTypes.h.

void vtkCellTypes::DeleteCell ( vtkIdType cellId ) [inline]

Delete cell by setting to NULL cell type.

Definition at line 74 of file vtkCellTypes.h.

int vtkCellTypes::GetNumberOfTypes ( ) [inline]

Return the number of types in the list.

Definition at line 77 of file vtkCellTypes.h.

int vtkCellTypes::IsType ( unsigned char type ) [inline]

Return 1 if type specified is contained in list; 0 otherwise.

Definition at line 137 of file vtkCellTypes.h.

int vtkCellTypes::InsertNextType ( unsigned char type ) [inline]

Add the type specified to the end of the list. Range checking is performed.

Definition at line 84 of file vtkCellTypes.h.

unsigned char vtkCellTypes::GetCellType ( int cellId ) [inline]

Return the type of cell.

Definition at line 87 of file vtkCellTypes.h.

void vtkCellTypes::Squeeze ( )

Reclaim any extra memory.

void vtkCellTypes::Reset ( )

Initialize object without releasing memory.

unsigned long vtkCellTypes::GetActualMemorySize ( )

Return the memory in kilobytes consumed by this cell type array. Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated.

void vtkCellTypes::DeepCopy ( vtkCellTypes * src )

Standard DeepCopy method. Since this object contains no reference to other objects, there is no ShallowCopy.

static const char* vtkCellTypes::GetClassNameFromTypeId ( int typeId ) [static]

Given an int (as defined in vtkCellType.h) identifier for a class return it's classname.

static int vtkCellTypes::GetTypeIdFromClassName ( const char * classname ) [static]

Given a data object classname, return it's int identified (as defined in vtkCellType.h)

int vtkCellTypes::IsLinear ( unsigned char type ) [inline, static]

This convenience method is a fast check to determine if a cell type represents a linear or nonlinear cell. This is generally much more efficient than getting the appropriate vtkCell and checking its IsLinear method.
