Detailed Description

A source that can accept input step by step, and can close input explicitly.

This source will not send data into the transformation chain when the chain is constructed. Input will be explicitly sent into the chain using write(...) and will be closed explicitly using end().

StepSource ss; ss >> transform1() >> transform2() >> sinkStream(...); ss.write(...); ... ss.write(...); ss.end();

Member Function Documentation

write()

size_t ndn::security::transform::StepSource::write

(

span< const uint8_t >

buf

)

Accept input data and directly write input into next transformation module.

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

Returns

number of bytes that has been written into next module

end()

void ndn::security::transform::StepSource::end

(

)

Close the input interface and directly notify the next module the end of input.
