getChannelLocation

public NetChannelLocation getChannelLocation()

Returns a new NetChannelLocation object which holds the information necessary for a networked ChannelOutput to establish a connection to this channel reader.

Returns:

the location information for this channel reader.

destroyReader

public void destroyReader()

Destroys this end of the channel.

getChannel

protected AltingChannelInput getChannel()

This method should not be called. The implementation channel is not available to subclasses of Net2OneChannel.

Overrides:

getChannel in class AltingChannelInputWrapper

Returns:

Always null.

getChannelIndex

long getChannelIndex()

getFactoryClass

public java.lang.Class getFactoryClass()

Description copied from interface: NetChannelInput

Returns a Class file of the factory used to construct the channel end.

Returns:

the Class of the factory class.

poison

public void poison(PoisonException poison)

Currently, network channels are unpoisonable so this method has no effect.

checkPoison

public void checkPoison()
                 throws PoisonException

Currently, network channels are unpoisonable so this method will never throw a PoisonException

Throws:

PoisonException
