Interface RestResourceResolver

All Superinterfaces:

ResourceResolver

All Known Subinterfaces:

RestResourceResolver.Null

All Known Implementing Classes:

BasicRestResourceResolver, SpringRestResourceResolver

public interface RestResourceResolver
extends ResourceResolver

Class used to resolve Class objects to instances.

Used to convert classes defined via @Rest(children) into child instances.

Subclasses can be created to provide customized resource resolution. These can be associated with REST resources in one of the following ways:

• @Rest(resourceResolver) annotation.
• RestContextBuilder.resourceResolver(Class)/RestContextBuilder.resourceResolver(RestResourceResolver) methods.

Implementations must provide one of the following public constructors:

• RestResourceResolver()
• RestResourceResolver(RestContext)

Method Detail

resolve

<T> T resolve(Object parent,
              Class<T> c,
              RestContextBuilder builder,
              Object... args)
       throws Exception

Resolves the specified class to a resource object.

Subclasses can override this method to provide their own custom resolution.

The default implementation simply creates a new class instance using Class.newInstance().

Parameters:

parent - The parent resource (i.e. the instance whose class has the @Rest(children) annotation.

c - The class to resolve.

builder - The initialization configuration for the resource.

args - Optional arguments to pass to constructor

Returns:

The instance of that class.

Throws:

Exception - If class could not be resolved.
