## Detailed Description

Wraps a binary output stream with a VTK interface.

Date:
  2002/10/16 18:23:06

Revision:
  1.1

vtkOutputStream provides a VTK-style interface wrapping around a standard output stream. The access methods are virtual so that subclasses can transparently provide encoding of the output. Data lengths for Write calls refer to the length of the data in memory. The actual length in the stream may differ for subclasses that implement an encoding scheme.

## Member Typedef Documentation

typedef vtkObject vtkOutputStream::Superclass

| Reimplemented from vtkObject. Reimplemented in vtkBase64OutputStream. Definition at line 48 of file vtkOutputStream.h.

## Constructor & Destructor Documentation

vtkOutputStream::vtkOutputStream | ( |  | ) | `[protected]`

vtkOutputStream::~vtkOutputStream | ( |  | ) | `[protected]`

## Member Function Documentation

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

| Reimplemented from vtkObject. Reimplemented in vtkBase64OutputStream.

int vtkOutputStream::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. Reimplemented in vtkBase64OutputStream.

virtual int vtkOutputStream::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. Reimplemented in vtkBase64OutputStream.

vtkOutputStream* vtkOutputStream::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkObject. Reimplemented in vtkBase64OutputStream.

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

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject. Reimplemented in vtkBase64OutputStream.

void vtkOutputStream::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. Reimplemented in vtkBase64OutputStream.

virtual void vtkOutputStream::SetStream | ( | ostream * |  | ) | `[virtual]`

| Get/Set the real output stream.

virtual ostream* vtkOutputStream::GetStream | ( |  | ) | `[virtual]`

| Get/Set the real output stream.

virtual int vtkOutputStream::StartWriting | ( |  | ) | `[virtual]`

| Called after the stream position has been set by the caller, but before any Write calls. The stream position should not be adjusted by the caller until after an EndWriting call. Reimplemented in vtkBase64OutputStream.

virtual int vtkOutputStream::Write | ( | const unsigned char * | data,
|  | unsigned long | length
| ) | `[virtual]`

| Write output data of the given length. Reimplemented in vtkBase64OutputStream.

int vtkOutputStream::Write | ( | const char * | data,
|  | unsigned long | length
| ) |

| Write output data of the given length.

virtual int vtkOutputStream::EndWriting | ( |  | ) | `[virtual]`

| Called after all desired calls to Write have been made. After this call, the caller is free to change the position of the stream. Additional writes should not be done until after another call to StartWriting. Reimplemented in vtkBase64OutputStream.
