Detailed Description

AndroMeta peer-to-peer application-level interface.

Provides an interface for an application to run through the AndroMeta peer-to-peer system, supporting unicast, broadcast, barrier, and various methods for querying the peer.

Member Function Documentation

void Meta::MPeerProc::barrier

(

)

Barrier sycnhronization -- block until all peers have entered the barrier.

bool Meta::MPeerProc::broadcast	(	const mvar &	msg,
		const mvar &	header = undef,
		bool	block = false
	)

Broadcast a message to all peers in the running group.

Parameters:

block

If false, do not wait for message to be delivered.

Returns:

true on success, fails if connection becomes closed while the operation is in progress.

void Meta::MPeerProc::close

(

)

Shutdown the peer process and close the connection to peer.

bool Meta::MPeerProc::connect	(	int	localPort,
		long	groupId,
		const mstr &	user,
		const mstr &	key
	)

Explicitly connect to a peer.

Returns:

true on success.

bool Meta::MPeerProc::connect

(

)

Uses the MProgram arguments to attempt to connect to a peer.

Returns:

true on success.

long Meta::MPeerProc::groupId

(

)

const

Returns:

The group id of this peer process.

virtual void Meta::MPeerProc::handleMessage	(	mvar &	msg,
		mvar &	header
	)			[pure virtual]

Reimplement to provide application-specific handling when a message is received.

bool Meta::MPeerProc::isConnected

(

)

const

Returns:

true if connected.

int Meta::MPeerProc::localPort

(

)

const

Returns:

The local port the peer is running on.

virtual void Meta::MPeerProc::onClose

(

long

peerId

)

[virtual]

Reimplement to provide applications-specific behavior when a peer exits the group.

virtual void Meta::MPeerProc::onClose

(

)

[virtual]

Reimplement to provide applications-specific behavior on close.

long Meta::MPeerProc::peerId

(

)

const

Returns:

The peer id this peer process is running as.

mvec Meta::MPeerProc::peers

(

)

const

Returns:

A vector of peer id's in the running group.

long Meta::MPeerProc::submitterId

(

)

const

Returns:

The peer id that submitted this process.

MProcTask* Meta::MPeerProc::task

(

)

Returns:

The MProcTask that the broker was constructed with.

bool Meta::MPeerProc::unicast	(	long	peerId,
		const mvar &	msg,
		const mvar &	header = undef,
		bool	block = false
	)

Send a message to a single peer.

Parameters:

block

If false, do not wait for message to be delivered.

Returns:

true on success, fails if connection becomes closed while the operation is in progress.
