ResolverServiceLayer

ResolverServiceLayer()
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
