Examples of org.jgroups.JChannel$MyProbeHandler

org.jgroups.JChannel
JChannel is a pure Java implementation of Channel. When a JChannel object is instantiated it automatically sets up the protocol stack.
Properties
Properties are used to configure a channel, and are accepted in several forms; the String form is described here. A property string consists of a number of properties separated by colons. For example:
```
"<prop1>(arg1=val1):<prop2>(arg1=val1;arg2=val2):<prop3>:<propn>"
```
Each property relates directly to a protocol layer, which is implemented as a Java class. When a protocol stack is to be created based on the above property string, the first property becomes the bottom-most layer, the second one will be placed on the first, etc.: the stack is created from the bottom to the top, as the string is parsed from left to right. Each property has to be the name of a Java class that resides in the {@link org.jgroups.protocols} package.
Note that only the base name has to be given, not the fully specified class name (e.g., UDP instead of org.jgroups.protocols.UDP).
Each layer may have 0 or more arguments, which are specified as a list of name/value pairs in parentheses directly after the property. In the example above, the first protocol layer has 1 argument, the second 2, the third none. When a layer is created, these properties (if there are any) will be set in a layer by invoking the layer's setProperties() method
As an example the property string below instructs JGroups to create a JChannel with protocols UDP, PING, FD and GMS:
```
"UDP(mcast_addr=228.10.9.8;mcast_port=5678):PING:FD:GMS"
```
The UDP protocol layer is at the bottom of the stack, and it should use mcast address 228.10.9.8. and port 5678 rather than the default IP multicast address and port. The only other argument instructs FD to output debug information while executing. Property UDP refers to a class {@link org.jgroups.protocols.UDP}, which is subsequently loaded and an instance of which is created as protocol layer. If any of these classes are not found, an exception will be thrown and the construction of the stack will be aborted. @author Bela Ban @version $Id: JChannel.java,v 1.209 2008/11/28 14:45:16 belaban Exp $
