Class MarshallerInspector

java.lang.Object

org.nuxeo.ecm.core.io.registry.reflect.MarshallerInspector

All Implemented Interfaces:

Comparable<MarshallerInspector>

public class MarshallerInspector
extends Object
implements Comparable<MarshallerInspector>

Utility class used to instanciate marshallers. This class checks if a marshaller has annotation Setup and inspect every attributes having Inject annotation.

To get a valid marshaller instance :

• Create an inspector for your marshaller class using constructor MarshallerInspector(Class). This will checks your marshaller has annotation Setup and inspect every attributes having Inject annotation.
• You can check it's a valid marshaller by calling @ #isValid()}
• You can check it's a Writer by calling isWriter()
• You can check it's a Reader by calling isReader()
• You can finally call getInstance(RenderingContext) to get a valid marshaller instance with RenderingContext and required services injected.

This class implements Comparable and then handle marshaller priorities rules: look at MarshallerRegistry javadoc to read the rules.

Since:

7.2

Constructor Detail

MarshallerInspector

public MarshallerInspector(Class<?> clazz)

Create an inspector for the given class.

Parameters:

clazz - The class to analyse and instantiate.

Method Detail

getInstance

public <T> T getInstance(RenderingContext ctx)

Create an instance of this marshaller. Depending on the instantiation mode, get the current singleton instance, get a thread local one or create a new one.

Parameters:

ctx - The RenderingContext to inject, if null create an empty context.

Returns:

                    boolean threadSafe)

Create a new instance of the marshaller.

Parameters:

ctx - The RenderingContext to inject.

Returns:

An instance of the marshaller.
