org.mule.transformer.simple
Class ObjectToString

java.lang.Object
  org.mule.transformer.AbstractTransformer
      org.mule.transformer.simple.ObjectToString

All Implemented Interfaces:

AnnotatedObject, MuleContextAware, Disposable, Initialisable, NameableObject, NamedObject, MessageProcessor, Converter, DiscoverableTransformer, Transformer, EndpointAware

public class ObjectToString
extends AbstractTransformer
implements DiscoverableTransformer

ObjectToString transformer is useful for debugging. It will return human-readable output for various kinds of objects. Right now, it is just coded to handle Map and Collection objects. Others will be added.

getPriorityWeighting

public int getPriorityWeighting()

Description copied from interface: Converter

If two or more discoverable transformers are equal, this value can be used to select the correct one

Specified by:

Returns:

the priority weighting for this transformer. This is a value between Converter.MIN_PRIORITY_WEIGHTING and Converter.MAX_PRIORITY_WEIGHTING.

setPriorityWeighting

public void setPriorityWeighting(int priorityWeighting)

Description copied from interface: Converter

If 2 or more discoverable transformers are equal, this value can be used to select the correct one

Specified by:

setPriorityWeighting in interface Converter
