Detailed Description

A ChannelPort which sends data to the accelerator.

connect()

virtual void esi::WriteChannelPort::connect ( std::optional< unsigned >  bufferSize = std::nullopt )

inlineoverridevirtual

Set up a connection to the accelerator.

The buffer size is optional and should be considered merely a hint. Individual implementations use it however they like. The unit is number of messages of the port type.

Implements esi::ChannelPort.

isConnected()

tryWrite()

virtual bool esi::WriteChannelPort::tryWrite ( const MessageData &  data )

pure virtual

A basic non-blocking write API.

Returns true if the data was written. It is invalid for backends to always return false (i.e. backends must eventually ensure that writes may succeed).

write()

virtual void esi::WriteChannelPort::write ( const MessageData &  )

pure virtual

A very basic blocking write API.

Will likely change for performance reasons.
