Constructor Detail

### 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
