## Detailed Description

Filter class that is a proxy for a sink.

Used By ProxyFilter

Since
  Crypto++ 4.0

Definition at line 990 of file filters.h.

## Constructor & Destructor Documentation

## OutputProxy()

OutputProxy::OutputProxy | ( | BufferedTransformation & | owner,
|  | bool | passSignal
| ) |  |

inline

Construct an OutputProxy.

Parameters

  owner | the owning transformation
  passSignal | flag indicating if signals should be passed

Definition at line 998 of file filters.h.

## Member Function Documentation

## GetPassSignal()

bool OutputProxy::GetPassSignal | ( |  | ) | const

inline

Retrieve passSignal flag.

Returns
  flag indicating if signals should be passed

Definition at line 1002 of file filters.h.

## SetPassSignal()

void OutputProxy::SetPassSignal | ( | bool | passSignal | ) |

inline

Set passSignal flag.

Parameters

  passSignal | flag indicating if signals should be passed

Definition at line 1005 of file filters.h.

## Initialize()

void OutputProxy::Initialize | ( | const NameValuePairs & | parameters = `g_nullNameValuePairs`,
|  | int | propagation = `-1`
| ) |  |

inline virtual

Initialize or reinitialize this object, with signal propagation.

Parameters

  parameters | a set of NameValuePairs to initialize or reinitialize this object
  propagation | the number of attached transformations the Initialize() signal should be passed

Initialize() is used to initialize or reinitialize an object using a variable number of arbitrarily typed arguments. The function avoids the need for multiple constructors providing all possible combintations of configurable parameters.

propagation count includes this object. Setting propagation to `1` means this object only. Setting propagation to `-1` means unlimited propagation.

Implements CustomSignalPropagation< Sink >.

Definition at line 1013 of file filters.h.

## Flush()

bool OutputProxy::Flush | ( | bool | hardFlush,
|  | int | propagation = `-1`,
|  | bool | blocking = `true`
| ) |  |

inline virtual

Flush buffered input and/or output, with signal propagation.

Parameters

  hardFlush | is used to indicate whether all data should be flushed
  propagation | the number of attached transformations the Flush() signal should be passed
  blocking | specifies whether the object should block when processing input

propagation count includes this object. Setting propagation to `1` means this object only. Setting propagation to `-1` means unlimited propagation.

Note
  Hard flushes must be used with care. It means try to process and output everything, even if there may not be enough data to complete the action. For example, hard flushing a HexDecoder would cause an error if you do it after inputing an odd number of hex encoded characters.
  For some types of filters, like ZlibDecompressor, hard flushes can only be done at "synchronization points". These synchronization points are positions in the data stream that are created by hard flushes on the corresponding reverse filters, in this example ZlibCompressor. This is useful when zlib compressed data is moved across a network in packets and compression state is preserved across packets, as in the SSH2 protocol.

Implements CustomFlushPropagation< T >.
