Method Detail

getDomainClassLoader

public java.lang.ClassLoader getDomainClassLoader()

Description copied from class: ServiceLayer

Returns the ClassLoader that should be used when attempting to access domain classes or resources.

The default implementation returns Thread.currentThread().getContextClassLoader().

Overrides:

getDomainClassLoader in class ServiceLayerDecorator

resolveClass

public java.lang.Class<? extends BaseProxy> resolveClass(java.lang.String typeToken)

Description copied from class: ServiceLayer

Given a type token previously returned from ServiceLayer.resolveTypeToken(Class), return the Class literal associated with the token.

Overrides:

resolveClass in class ServiceLayerDecorator

Parameters:

typeToken - a string token

Returns:

the type represented by the token

resolveClientType

public <T> java.lang.Class<? extends T> resolveClientType(java.lang.Class<?> domainClass,
                                                          java.lang.Class<T> clientClass,
                                                          boolean required)

Description copied from class: ServiceLayer

Determine the type used by the client code to represent a given domain type. If multiple proxy types have been mapped to the same domain type, the clientType parameter is used to ensure assignability.

Overrides:

resolveClientType in class ServiceLayerDecorator

Parameters:

domainClass - the server-side type to be transported to the client

clientClass - the type to which the returned type must be assignable

required - if true and no mapping is available, throw an exception, otherwise the method will return null

Returns:

a class that represents domainClass on the client which is assignable to clientType

resolveDomainClass

public java.lang.Class<?> resolveDomainClass(java.lang.Class<?> clazz)

Description copied from class: ServiceLayer

Determine the domain (server-side) type that the given client type is mapped to.

Overrides:

resolveDomainClass in class ServiceLayerDecorator

Parameters:

clazz - a client-side type

Returns:

the domain type that clientType represents

resolveDomainMethod

public java.lang.reflect.Method resolveDomainMethod(java.lang.String operation)

Description copied from class: ServiceLayer

Return the domain service method associated with a RequestContext method declaration. The requestContextMethod will have been previously resolved by #resolveRequestContextMethod(String, String).

Overrides:

resolveDomainMethod in class ServiceLayerDecorator

Returns:

the domain service method that should be invoked

resolveRequestContext

public java.lang.Class<? extends RequestContext> resolveRequestContext(java.lang.String operation)

Description copied from class: ServiceLayer

Find a RequestContext that should be used to fulfill the requested operation.

Overrides:

resolveRequestContext in class ServiceLayerDecorator

Parameters:

operation - the operation

Returns:

the RequestContext or null if no RequestContext exists that can fulfill the operation

resolveRequestContextMethod

public java.lang.reflect.Method resolveRequestContextMethod(java.lang.String operation)

Description copied from class: ServiceLayer

Find a RequestContext method declaration by name.

Overrides:

resolveRequestContextMethod in class ServiceLayerDecorator

Parameters:

operation - the operation's name

Returns:

the method declaration, or null if the method does not exist

resolveRequestFactory

public java.lang.Class<? extends RequestFactory> resolveRequestFactory(java.lang.String binaryName)

Description copied from class: ServiceLayer

Loads and validates a RequestFactory interface.

Overrides:

resolveRequestFactory in class ServiceLayerDecorator

Parameters:

binaryName - the RequestFactory's type token (usually the type's binary name)

Returns:

the RequestFactory type

resolveServiceClass

public java.lang.Class<?> resolveServiceClass(java.lang.Class<? extends RequestContext> requestContextClass)

Description copied from class: ServiceLayer

Given a RequestContext method, find the service class referenced in the Service or ServiceName annotation.

Overrides:

resolveServiceClass in class ServiceLayerDecorator

Parameters:

requestContextClass - a RequestContext interface

Returns:

the type of service to use

resolveTypeToken

public java.lang.String resolveTypeToken(java.lang.Class<? extends BaseProxy> clazz)

Description copied from class: ServiceLayer

Return a string used to represent the given type in the wire protocol.

Overrides:

resolveTypeToken in class ServiceLayerDecorator

Parameters:

clazz - a client-side EntityProxy or ValueProxy type

Returns:

the type token used to represent the proxy type
