Class Invocable

java.lang.Object
  org.glassfish.jersey.server.model.Invocable

All Implemented Interfaces:

Parameterized, ResourceModelComponent

public final class Invocable
extends java.lang.Object
implements Parameterized, ResourceModelComponent

A common interface for invocable resource components. This includes resource methods, sub-resource methods and sub-resource locators bound to a concrete handler class and a Java method (either directly or indirectly) declared & implemented by the handler class.

Invocable component information is used at runtime by a Java method dispatcher when processing requests.

Method Detail

create

public static <T> Invocable create(Inflector<Request,T> inflector)

Create a new resource method invocable model backed by an inflector instance.

Parameters:

inflector - inflector processing the request method.

create

public static Invocable create(java.lang.Class<? extends Inflector> inflectorClass)

Create a new resource method invocable model backed by an inflector class.

Parameters:

inflectorClass - inflector syb-type processing the request method.

create

public static Invocable create(MethodHandler handler,
                               java.lang.reflect.Method handlingMethod)

Create a new resource method invocable model. Parameter values will be automatically decoded.

Parameters:

handler - resource method handler.

handlingMethod - handling Java method.

create

public static Invocable create(MethodHandler handler,
                               java.lang.reflect.Method handlingMethod,
                               boolean encodedParameters)

Create a new resource method invocable model.

Parameters:

handler - resource method handler.

handlingMethod - handling Java method.

encodedParameters - true if the automatic parameter decoding should be disabled, false otherwise.

getHandler

public MethodHandler getHandler()

Get the model of the resource method handler that will be used to invoke the handling resource method on.

Returns:

resource method handler model.

getHandlingMethod

public java.lang.reflect.Method getHandlingMethod()

Getter for the Java method

Returns:

corresponding Java method

getResponseType

public java.lang.reflect.Type getResponseType()

Get the resource method generic response type information.

The returned value provides the Type information that contains additional generic declaration information for generic Java class types.

Returns:

resource method generic response type information.

getRawResponseType

public java.lang.Class<?> getRawResponseType()

Get the resource method raw response type.

The returned value provides information about the raw Java class.

Returns:

resource method raw response type information.

isInflector

public boolean isInflector()

Check if the invocable represents an inflector processing method.

Returns:

true, if this invocable represents an inflector invocation, false otherwise.

requiresEntity

Description copied from interface: Parameterized

Provides access to all parameters associated with given Parameterized instance.

Specified by:

getParameters in interface Parameterized

Returns:

list of actual parameters

accept

public void accept(ResourceModelVisitor visitor)

Description copied from interface: ResourceModelComponent

A component should call the visitor back with an appropriate visitor interface method to give it a chance to process.

Specified by:

accept in interface ResourceModelComponent

Parameters:

visitor - resource model visitor.

getComponents

public java.util.List<? extends ResourceModelComponent> getComponents()

Description copied from interface: ResourceModelComponent
