Last updated Friday, 21 July 2017When you create a message flow, you include input nodes that receive messages and, optionally, output nodes that send out new or updated messages. If the message processing requires it, you can include other nodes after the input node that are customized in Java™ to complete the actions that your applications need.
You can customize the processing that some of the built-in nodes provide. In a JavaCompute node, you can provide Java code that controls precisely the behavior of the node. This set of topics discusses how you can use Java to customize the JavaCompute node.
You can use a JavaCompute node to check and manipulate message content. The node can read the contents of the input message, then construct new output messages that are created from all, part, or none of the input message.
You can also use a JavaCompute node to interact with a global cache. You can write Java code that stores data in a global cache, or retrieves data for further processing or routing.
Use the Debug perspective to debug a message flow that contains a JavaCompute node. When control passes to a JavaCompute node during debugging, the perspective opens the Java debugger, allowing you to step through the Java class code for the node.
