Interface ServiceBinder

All Known Implementing Classes:

ServiceBinderImpl

public interface ServiceBinder

Allows a module to bind service interfaces to service implementation classes in support of autobuilding services. A ServiceBinder is passed to to a method with the following signature: public static void bind(ServiceBinder binder). This is an adaptation of ideas from Guice.

Method Summary

Modifier and Type	Method	Description
<T> ServiceBindingOptions	bind(Class<T> implementationClass)	Defines a service in terms of an implementation class, without a service interface.
<T> ServiceBindingOptions	bind(Class<T> serviceInterface, Class<? extends T> serviceImplementation)	Binds the service interface to a service implementation class.
<T> ServiceBindingOptions	bind(Class<T> serviceInterface, ServiceBuilder<T> builder)	Alternative implementation that supports a callback to build the service, rather than instantiating a particular class.

Method Detail

bind

<T> ServiceBindingOptions bind(Class<T> implementationClass)

Defines a service in terms of an implementation class, without a service interface. In this case, the service will not be proxiable (proxying requires a service interface) and ServiceDef.getServiceInterface() will return the implementation class. In this situation, the service will not be proxied; it will be instantiated fully on first reference (ignoring its scope, if any) and will not be decorated.

Type Parameters:

T -

Parameters:

implementationClass - class to instantiate as the service

Returns:

binding options, used to specify additional details about the service

bind

<T> ServiceBindingOptions bind(Class<T> serviceInterface,
                               ServiceBuilder<T> builder)

Alternative implementation that supports a callback to build the service, rather than instantiating a particular class.

Parameters:

serviceInterface - interface implemented by the service

builder - constructs the core service implementation

Returns:

binding options, used to specify additional details about the service

bind

<T> ServiceBindingOptions bind(Class<T> serviceInterface,
                               Class<? extends T> serviceImplementation)

Binds the service interface to a service implementation class. The default service name is the unqualified name of the service interface. The default service scope is "singleton", unless the service implementation class includes the Scope annotation.

Type Parameters:

T -

Parameters:

serviceInterface - service interface (used when locating services, and when building proxies)

serviceImplementation - implementation class that implements the service interface

Returns:

binding options, used to specify additional details about the service
