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.

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.

virtual const char* vtkCellTypes::GetClassName  )  [virtual]

Reimplemented from vtkObject.

static int vtkCellTypes::IsTypeOf const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkCellTypes::IsA const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkCellTypes* vtkCellTypes::SafeDownCast vtkObject o  )  [static]

Reimplemented from vtkObject.

void vtkCellTypes::PrintSelf ostream &  os,
vtkIndent  indent

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 67 of file vtkCellTypes.h.

void vtkCellTypes::DeleteCell int  cellId  )  [inline]

Delete cell by setting to NULL cell type.

Definition at line 70 of file vtkCellTypes.h.

References VTK_EMPTY_CELL.

Referenced by vtkPolyData::DeleteCell().

int vtkCellTypes::GetNumberOfTypes  )  [inline]

Return the number of types in the list.

Definition at line 73 of file vtkCellTypes.h.

Referenced by IsType().

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

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

Definition at line 119 of file vtkCellTypes.h.

References GetNumberOfTypes().

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

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

Definition at line 80 of file vtkCellTypes.h.

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

Return the type of cell.

Definition at line 83 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.
