Detailed Description

A proxy connection buffering outgoing data into a memory region.

Member Function Documentation

virtual void eq::net::BufferConnection::readNB	(	void *	buffer,
		const uint64_t	bytes
	)			`[inline, protected, virtual]`

Start a read operation on the connection.

This method is the low-level counterpart to recvNB().

This function returns immediately. The operation's Notifier will signal data availability, upon which readSync() should be used to finish the operation.

Parameters:

	buffer	the buffer receiving the data.
	bytes	the number of bytes to read.

See also:: readSync()

Implements eq::net::Connection.

Definition at line 42 of file bufferConnection.h.

virtual int64_t eq::net::BufferConnection::readSync	(	void *	buffer,
		const uint64_t	bytes
	)			`[inline, protected, virtual]`

Finish reading data from the connection.

This method is the low-level counterpart to recvSync(). It may return with a partial read.

Parameters:

	buffer	the buffer receiving the data.
	bytes	the number of bytes to read.

Returns:: the number of bytes read, or -1 upon error.

Implements eq::net::Connection.

Definition at line 44 of file bufferConnection.h.

int64_t eq::net::BufferConnection::write	(	const void *	buffer,
		const uint64_t	bytes
	)			`[protected, virtual]`

Write data to the connection.

Parameters:

	buffer	the buffer containing the message.
	bytes	the number of bytes to write.

Returns:: the number of bytes written, or -1 upon error.

Implements eq::net::Connection.
