Method Detail

isHK2Managed

public static boolean isHK2Managed(java.lang.Class<?> type)

Parameters:

type - type to check

Returns:

true if type annotated with HK2Managed, false otherwise

HK2Managed

bindComponent

public static void bindComponent(org.glassfish.hk2.utilities.binding.AbstractBinder binder,
                                 com.google.inject.Injector injector,
                                 java.lang.Class<?> type)

Binds component into HK context. If component is annotated with HK2Managed, then registers type, otherwise register guice "bridge" factory around component.

Parameters:

binder - hk binder

injector - guice injector

type - component type

See Also:

GuiceComponentFactory

bindFactory

public static <T> void bindFactory(org.glassfish.hk2.utilities.binding.AbstractBinder binder,
                                   com.google.inject.Injector injector,
                                   java.lang.Class<?> type)

Binds hk Factory. If bean is HK2Managed then registered directly as factory. Otherwise register factory through special "lazy bridge" to delay guice factory bean instantiation. Also registers factory directly (through wrapper to be able to inject factory by its type).

Type Parameters:

T - actual type (used to workaround type checks)

Parameters:

binder - hk binder

injector - guice injector

type - factory to bind

LazyGuiceFactory, GuiceComponentFactory

bindSpecificComponent

public static void bindSpecificComponent(org.glassfish.hk2.utilities.binding.AbstractBinder binder,
                                         com.google.inject.Injector injector,
                                         java.lang.Class<?> type,
                                         java.lang.Class<?> specificType)

Binds jersey specific component (component implements jersey interface or extends class). Specific binding is required for types directly supported by jersey (e.g. ExceptionMapper). Such types must be bound to target interface directly, otherwise jersey would not be able to resolve them.

If type is HK2Managed, binds directly. Otherwise, use guice "bridge" factory to lazily bind type.

Shortcut methods provided for most common cases.

Parameters:

binder - hk binder

injector - guice injector

type - type which implements specific jersey interface or extends class

specificType - specific jersey type (interface or abstract class)

bindJerseyComponent

public static <T> com.google.inject.binder.ScopedBindingBuilder bindJerseyComponent(com.google.inject.Binder binder,
                                                                                    javax.inject.Provider<com.google.inject.Injector> provider,
                                                                                    java.lang.Class<T> type)

Used to bind jersey beans in guice context (lazily). Guice context is started first, so there is no way to bind instances. Instead "lazy bridge" installed, which will resolve target type on first call. Guice is not completely started and direct injector lookup is impossible here, so lazy injector provider used.

Type Parameters:

T - type

Parameters:

binder - guice binder

provider - provider for guice injector

type - jersey type to register

Returns:

scoped binder object to optionally define binding scope.
