Detailed Description

dynamic, self-adjusting array of bits

vtkBitArray is an array of bits (0/1 data value). The array is packed so that each byte stores eight bits. vtkBitArray provides methods for insertion and retrieval of bits, and will automatically resize itself to hold new data.

Member Function Documentation

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

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

Reimplemented from vtkObject.

static int vtkBitArray::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 vtkDataArray.

virtual int vtkBitArray::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 vtkDataArray.

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

Reimplemented from vtkDataArray.

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

Reimplemented from vtkDataArray.

vtkBitArray* vtkBitArray::NewInstance ( ) const

Reimplemented from vtkDataArray.

void vtkBitArray::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 vtkDataArray.

int vtkBitArray::Allocate	(	vtkIdType	sz,
		vtkIdType	ext = `1000`
	)		`[virtual]`

Allocate memory for this array. Delete old storage only if necessary. Note that ext is no longer used.

Implements vtkAbstractArray.

void vtkBitArray::Initialize ( ) [virtual]

Release storage and reset array to initial state.

Implements vtkAbstractArray.

int vtkBitArray::GetDataType ( ) [inline, virtual]

Return the underlying data type. An integer indicating data type is returned as specified in vtkSetGet.h.

Implements vtkAbstractArray.

Definition at line 50 of file vtkBitArray.h.

int vtkBitArray::GetDataTypeSize ( ) [inline, virtual]

Return the size of the underlying data type. For a bit, 0 is returned. For string 0 is returned. Arrays with variable length components return 0.

Implements vtkAbstractArray.

Definition at line 51 of file vtkBitArray.h.

void vtkBitArray::SetNumberOfTuples ( vtkIdType number ) [virtual]

Set the number of n-tuples in the array.

Implements vtkAbstractArray.

virtual void vtkBitArray::SetTuple	(	vtkIdType	i,
		vtkIdType	j,
		vtkAbstractArray *	source
	)		`[virtual]`

Set the tuple at the ith location using the jth tuple in the source array. This method assumes that the two arrays have the same type and structure. Note that range checking and memory allocation is not performed; use in conjunction with SetNumberOfTuples() to allocate space.

Implements vtkDataArray.

virtual void vtkBitArray::InsertTuple	(	vtkIdType	i,
		vtkIdType	j,
		vtkAbstractArray *	source
	)		`[virtual]`

Insert the jth tuple in the source array, at ith location in this array. Note that memory allocation is performed as necessary to hold the data.

Implements vtkDataArray.

virtual vtkIdType vtkBitArray::InsertNextTuple	(	vtkIdType	j,
		vtkAbstractArray *	source
	)		`[virtual]`

Insert the jth tuple in the source array, at the end in this array. Note that memory allocation is performed as necessary to hold the data. Returns the location at which the data was inserted.

Implements vtkDataArray.

double* vtkBitArray::GetTuple ( vtkIdType i ) [virtual]

Get a pointer to a tuple at the ith location. This is a dangerous method (it is not thread safe since a pointer is returned).

Implements vtkDataArray.

void vtkBitArray::GetTuple	(	vtkIdType	i,
		double *	tuple
	)		`[virtual]`

Copy the tuple value into a user-provided array.

Implements vtkDataArray.

Insert (memory allocation performed) the tuple onto the end of the array.

Implements vtkDataArray.

void vtkBitArray::SetComponent	(	vtkIdType	i,
		int	j,
		double	c
	)		`[virtual]`

Set the data component at the ith tuple and jth component location. Note that i is less then NumberOfTuples and j is less then NumberOfComponents. Make sure enough memory has been allocated (use SetNumberOfTuples() and SetNumberOfComponents()).

Reimplemented from vtkDataArray.

void vtkBitArray::Squeeze ( ) [inline, virtual]

Free any unneeded memory.

Implements vtkAbstractArray.

void vtkBitArray::SetNumberOfValues ( vtkIdType number ) [inline]

Fast method based setting of values without memory checks. First use SetNumberOfValues then use SetValue to actually set them. Specify the number of values for this object to hold. Does an allocation as well as setting the MaxId ivar. Used in conjunction with SetValue() method for fast insertion.

Definition at line 237 of file vtkBitArray.h.

void vtkBitArray::SetValue	(	vtkIdType	id,

Reimplemented from vtkDataArray.

Definition at line 167 of file vtkBitArray.h.

void vtkBitArray::SetArray	(	unsigned char *	array,
		vtkIdType	size,
		int	save
	)

This method lets the user specify data to be held by the array. The array argument is a pointer to the data. size is the size of the array supplied by the user. Set save to 1 to keep the class from deleting the array when it cleans up or reallocates memory. The class uses the actual array provided; it does not copy the data from the suppled array. If save 0, the array must have been allocated with new[] not malloc.

void vtkBitArray::SetVoidArray	(	void *	array,
		vtkIdType	size,
		int	save
	)		`[inline]`

If save 0, the array must have been allocated with new[] not malloc.

Definition at line 180 of file vtkBitArray.h.

vtkArrayIterator* vtkBitArray::NewIterator ( ) [virtual]

Returns a new vtkBitArrayIterator instance.

Implements vtkAbstractArray.

virtual vtkIdType vtkBitArray::LookupValue ( vtkVariant value ) [virtual]

Return the indices where a specific value appears.

Implements vtkAbstractArray.

virtual void vtkBitArray::LookupValue	(	vtkVariant	value,
		vtkIdList *	ids

Return the indices where a specific value appears.

Implements vtkAbstractArray.

vtkIdType vtkBitArray::LookupValue ( int value )

void vtkBitArray::LookupValue	(	int	value,
		vtkIdList *	ids
	)

Return the indices where a specific value appears.

virtual void vtkBitArray::DataChanged ( ) [virtual]

Tell the array explicitly that the data has changed. This is only necessary to call when you modify the array contents without using the array's API (i.e. you retrieve a pointer to the data and modify the array contents). You need to call this so that the fast lookup will know to rebuild itself. Otherwise, the lookup functions will give incorrect results.

Implements vtkAbstractArray.

virtual void vtkBitArray::ClearLookup ( ) [virtual]

Delete the associated fast lookup data structure on this array, if it exists. The lookup will be rebuilt on the next call to a lookup function.

Implements vtkAbstractArray.
