Constructor Detail

ChannelRendererFactoryImpl

public ChannelRendererFactoryImpl(java.lang.String keyBase)

Creates a new instance of a bounded thread pool channel renderer factory object. The constructor should not be invoked directly; it should only be constructed by the ChannelRendererFactory object.

This factory implooks for the properties:

  keyBase + ".threadPool_initialThreads"
  keyBase + ".threadPool_maxThreads"
  keyBase + ".threadPool_threadPriority"
  keyBase + ".threadPool_shared"
 

in the configuration system and then reflectively constructs the factory class with the default (no-argument) constructor.

Parameters:

keyBase - configuration base key or null

Method Detail

newInstance

public IChannelRenderer newInstance(IChannel channel,
                                    ChannelRuntimeData channelRuntimeData)

Creates a new instance of a channel renderer object.

Specified by:

newInstance in interface IChannelRendererFactory

Parameters:

channel - channel to render

channelRuntimeData - runtime data for the channel to render

Returns:

new instance of a channel renderer for the specified channel
