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.

		vtkIdType	size,
		int	save,
		int	deleteMethod = `VTK_DATA_ARRAY_DELETE`
	)

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 supplied array. If the delete method is VTK_DATA_ARRAY_USER_DEFINED a custom free function can be assigned to be called using SetArrayFreeFunction, if no custom function is assigned we will default to delete[].

◆ SetVoidArray() [1/2]

inlineoverride

This method lets the user specify data to be held by the array.

If the delete method is VTK_DATA_ARRAY_USER_DEFINED a custom free function can be assigned to be called using SetArrayFreeFunction, if no custom function is assigned we will default to delete[].

◆ SetVoidArray() [2/2]

void vtkBitArray::SetVoidArray	(	void *	array,
		vtkIdType	size,
		int	save,
		int	deleteMethod
	)

inlineoverride

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 supplied array. If the delete method is VTK_DATA_ARRAY_USER_DEFINED a custom free function can be assigned to be called using SetArrayFreeFunction, if no custom function is assigned we will default to delete[].

Definition at line 254 of file vtkBitArray.h.

◆ SetArrayFreeFunction()

void vtkBitArray::SetArrayFreeFunction ( void(*)(void *) callback )

overridevirtual

This method allows the user to specify a custom free function to be called when the array is deallocated.

Calling this method will implicitly mean that the given free function will be called when the class cleans up or reallocates memory.

Implements vtkAbstractArray.

◆ NewIterator()

vtkArrayIterator * vtkBitArray::NewIterator ( )

overridevirtual

Returns a new vtkBitArrayIterator instance.

Implements vtkAbstractArray.

◆ LookupValue() [1/4]

		vtkIdList *	ids
	)

Return the indices where a specific value appears.

◆ DataChanged()

void vtkBitArray::DataChanged ( )

overridevirtual

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.

◆ ClearLookup()

void vtkBitArray::ClearLookup ( )

overridevirtual

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.

◆ InitializeUnusedBitsInLastByte()

virtual void vtkBitArray::InitializeUnusedBitsInLastByte ( )

protectedvirtual

This method should be called whenever MaxId needs to be changed, as this method fills the unused bits of the last byte to zero.

If those bits are kept uninitialized, one can trigger errors when reading the last byte.

Note: This method can be called with this->MaxId < 0. In this instance, nothing happens.

Warning: The buffer this->Array needs to already be allocated prior to calling this method.
