Member Function Documentation

void ndn::security::transform::Downstream::end ( )

inherited

Close the input interface of a module.

This method will notify this module that there is no more input and that the module should finalize transformation.

Although end() can be invoked multiple times, only the first invocation takes effect.

Definition at line 52 of file transform-base.cpp.

size_t ndn::security::transform::Downstream::getIndex ( ) const

inlineinherited

Get the module index.

Definition at line 125 of file transform-base.hpp.

bool ndn::security::transform::Downstream::isEnd ( ) const

inlineinherited

Check if the input interface of a module is closed.

Definition at line 107 of file transform-base.hpp.

void ndn::security::transform::Downstream::setIndex ( size_t  index )

inlineinherited

Set the module index.

Definition at line 116 of file transform-base.hpp.

size_t ndn::security::transform::Downstream::write ( const uint8_t *  buf, size_t  size  )

inherited

Accept input data and perform transformation.

An upstream module should call this method to write data into this module. The written data will be transformed and the result will be written into the next downstream module.

An upstream module can keep calling this method to until end() is called, which indicates the end of input. After that, calling this method will cause Error.

If a Downstream implementation expects structured input (e.g., hex decoding requires byte-pair), it should not return less than size if final portion of input is not a complete record.

Returns

number of bytes that has been written into this module

Exceptions

Error

if this module is closed or transformation error happens.
