Class ObjectToString

java.lang.Object

org.mule.runtime.api.meta.AbstractAnnotatedObject

org.mule.runtime.core.transformer.AbstractTransformer

org.mule.runtime.core.internal.transformer.simple.ObjectToString

All Implemented Interfaces:

Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>, org.mule.runtime.api.lifecycle.Disposable, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.meta.AnnotatedObject, org.mule.runtime.api.meta.NameableObject, org.mule.runtime.api.meta.NamedObject, MuleContextAware, Processor, ReactiveProcessor, Converter, DiscoverableTransformer, Transformer

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:

getPriorityWeighting in interface Converter

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

Parameters:

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