Detailed Description

The client represents a network node of the application in the cluster.

The methods initLocal() and exitLocal() should be used to set up and exit the listening node instance for each application process.

Member Function Documentation

virtual void eq::Client::clientLoop

(

)

[protected, virtual]

Implements the processing loop for render clients.

As long as the node is running, that is, between initLocal() and an exit send from the server, this method executes received commands using processCommand() and triggers the message pump between commands.

See also:

Pipe::createMessagePump()

Version:

1.0

Reimplemented in eqPly::EqPly, and eVolve::EVolve.

Referenced by eVolve::EVolve::clientLoop().

Here is the caller graph for this function:

bool eq::Client::connectServer

(

ServerPtr

server

)

Open and connect an Equalizer server to the local client.

The client has to be in the listening state, see initLocal().

Parameters:

server

the server.

Returns:

true if the server was connected, false if not.

Version:

1.0

Referenced by osgScaleViewer::OSGScaleViewer::run(), and eqPly::EqPly::run().

Here is the caller graph for this function:

bool eq::Client::disconnectServer

(

ServerPtr

server

)

Disconnect and close the connection to an Equalizer server.

Parameters:

server

the server.

Returns:

true if the server was disconnected, false if not.

Version:

1.0

Referenced by osgScaleViewer::OSGScaleViewer::run(), and eqPly::EqPly::run().

Here is the caller graph for this function:

virtual void eq::Client::exitClient

(

)

[protected, virtual]

Exit the process cleanly on render clients.

Version:

1.0

virtual bool eq::Client::exitLocal

(

)

[virtual]

De-initialize a local, listening node.

Version:

1.1.6

Reimplemented from co::LocalNode.

virtual co::CommandQueue* eq::Client::getMainThreadQueue

(

)

[inline, virtual]

Returns:

the command queue to the main node thread.

Implements eq::fabric::Client.

Definition at line 97 of file include/eq/client/client.h.

bool eq::Client::hasCommands

(

)

Returns:

true if the client has commands pending, false otherwise.

Version:

1.0

Referenced by eqPly::EqPly::run().

Here is the caller graph for this function:

virtual bool eq::Client::initLocal	(	const int	argc,
		char **	argv
	)		[virtual]

Initialize a local, listening node.

The --eq-client and --eq-layout command line options are recognized by this method.

--eq-client is used for remote nodes which have been auto-launched by another node, e.g., remote render clients. This method does not return when this command line option is present.

--eq-layout can apply multiple times. Each instance has to be followed by the name of a layout. The given layouts will be activated on all canvases using them during Config::init().

Parameters:

argc	the command line argument count.
argv	the command line argument values.

Returns:

true if the client was successfully initialized, false otherwise.

Version:

1.0

Reimplemented from co::LocalNode.
