## Detailed Description

A filter that buffers input using a ByteQueue.

FilterWithInputQueue will buffer input using a ByteQueue. When the filter receives a MessageEnd() signal it will pass the data on to its attached transformation.

Definition at line 419 of file filters.h.

## Constructor & Destructor Documentation

## FilterWithInputQueue()

FilterWithInputQueue::FilterWithInputQueue | ( | BufferedTransformation * | attachment = `NULL` | ) |

inline

Construct a FilterWithInputQueue.

Parameters

  attachment | an optional attached transformation

Definition at line 424 of file filters.h.

## Member Function Documentation

## Put2()

size_t FilterWithInputQueue::Put2 | ( | const byte * | inString,
|  | size_t | length,
|  | int | messageEnd,
|  | bool | blocking
| ) |  |

inline virtual

Input multiple bytes for processing.

Parameters

  inString | the byte buffer to process
  length | the size of the string, in bytes
  messageEnd | means how many filters to signal MessageEnd() to, including this one
  blocking | specifies whether the object should block when processing input

Derived classes must implement Put2().

Implements BufferedTransformation.
