## Detailed Description

dynamic, self-adjusting array of void* pointers

Date:
  2002/11/12 18:32:04

Revision:
  1.52

vtkVoidArray is an array of pointers to void. It provides methods for insertion and retrieval of these pointers values, and will automatically resize itself to hold new data.

## Member Function Documentation

vtkVoidArray* vtkVoidArray::New | ( |  | ) | `[static]`

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

virtual const char* vtkVoidArray::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkDataArray.

int vtkVoidArray::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 vtkDataArray.

virtual int vtkVoidArray::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 vtkDataArray.

| Reimplemented from vtkDataArray.

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