Class AbstractSimpleJsonFilter

java.lang.Object

de.caff.io.json.AbstractSimpleJsonFilter

All Implemented Interfaces:

SimpleJsonReader.Handler

public abstract class AbstractSimpleJsonFilter
extends java.lang.Object
implements SimpleJsonReader.Handler

Abstract basic low-level JSON filter. This acts as a handler for a SimpleJsonReader and writes its output to the wrapped SimpleJsonWriter.

This class is thought for simple transformations like exchanging a key or value.

This default implementation just forwards everything to the writer. Extending classes may intercept where they seem fit.
