Detailed Description

A source taking an std::istream as input.

Definition at line 34 of file stream-source.hpp.

Constructor & Destructor Documentation

StreamSource()

ndn::security::transform::StreamSource::StreamSource ( std::istream &  is, size_t  bufLen = DEFAULT_BUFFER_LEN  )

explicit

Construst a source using is as input.

Parameters

is	The input stream
bufLen	The internal buffer size. The default size is 1024.

Precondition

bufLen must be larger than 0.

operator>>() [1/2]

Source & ndn::security::transform::Source::operator>> ( unique_ptr< Transform >  transform )

inherited

Connect to an intermediate transformation module.

Definition at line 166 of file transform-base.cpp.

operator>>() [2/2]

void ndn::security::transform::Source::operator>> ( unique_ptr< Sink >  sink )

inherited

Connect to the last transformation module.

This method will trigger the source to pump data into the transformation pipeline.

pump()

void ndn::security::transform::Source::pump ( )

protectedinherited

Pump all data into next transformation module.
