Deprecated. Use a shared transport instead of the multiplexer

Description copied from interface: ChannelFactory

Creates an implementation of the Channel using a given stack name and registering it under a given identity.

Channel has to be created with a unique application id per stack name.

Provided stack name has to be one of the stacks defined in a property file that was passed to setMultiplexerConfig (e.g conf/stacks.xml). If clients attempt to create a Channel for an undefined stack name or they attempt to register a duplicate Channel per stack an Exception will be thrown.

Specified by:

createMultiplexerChannel in interface ChannelFactory

stack_name -

id -

Returns:

Throws:

java.lang.Exception

ChannelException

createMultiplexerChannel

public Channel createMultiplexerChannel(java.lang.String stack_name,
                                        java.lang.String id,
                                        boolean register_for_state_transfer,
                                        java.lang.String substate_id)
                                 throws java.lang.Exception

Deprecated. Use a shared transport instead of the multiplexer

Description copied from interface: ChannelFactory

Creates an implementation of the Channel using a given stack name and registering it under a given identity.

Channel has to be created with a unique application id per stack name.

Provided stack name has to be one of the stacks defined in a property file that was passed to setMultiplexerConfig (e.g conf/stacks.xml). If clients attempt to create a Channel for an undefined stack name or they attempt to register a duplicate Channel per stack an Exception will be thrown.

Rather than having each multiplexed channel do a separate state transfer clients can bundle state transfers for all channels created with the same ChannelFactory. First of all, clients have to create Channels with register_for_state_transfer set to true. After the last Channel that was created with register_for_state_transfer set to true connects and initiates state transfer the actual state transfer for all such channels from this ChannelFactory is executed.

Using bundled state transfers is especially useful with the FLUSH protocol in a stack. Recall that each state transfer triggers a flush and thus instead of doing a separate flush for each Channel created with this ChannelFactory we execute only one flush for all state transfers.

However, be aware of the implication of asynchronous nature of bundled state transfer with the respect of channel connect. Recall that each Channel after it returns from successful getState method can assume that state is available. In case of bundled state transfer, state will be set only after the last Channel registered for the bundled state transfer connects and executes getState.

Specified by:

createMultiplexerChannel in interface ChannelFactory

Parameters:

stack_name -

id -

register_for_state_transfer -

substate_id -

Throws:
