Class StringProcessorAbstract

java.lang.Object
  org.janux.bus.processor.StringProcessorAbstract

All Implemented Interfaces:

Processor, StringProcessor

public abstract class StringProcessorAbstract
extends Object
implements StringProcessor

Abstract base implementation of SpringProcessor that implements a template method for the inherited method Processor.process(InputStream, OutputStream) that converts the InputStream into a String, processes the String, and writes the processed String into the OutputStream; sub-classes should provide an implementation of the StringProcessor.process(String) method.

Optionally, implementing classes can specify different Charsets for respectively decoding/encoding the Input/Output streams. If either is null, the default character set for the system would be used for either decoding or encoding, respectively.
