Class InterceptorBinding

java.lang.Object

com.google.inject.spi.InterceptorBinding

All Implemented Interfaces:

Element

public final class InterceptorBinding
extends java.lang.Object
implements Element

Registration of interceptors for matching methods of matching classes. Instances are created explicitly in a module using bindInterceptor() statements:

     bindInterceptor(Matchers.subclassesOf(MyAction.class),
         Matchers.annotatedWith(Transactional.class),
         new MyTransactionInterceptor());

or from an injectable type listener using TypeEncounter.bindInterceptor().

Since:

2.0

Method Detail

getSource

public java.lang.Object getSource()

Description copied from interface: Element

Returns an arbitrary object containing information about the "place" where this element was configured. Used by Guice in the production of descriptive error messages.

Tools might specially handle types they know about; StackTraceElement is a good example. Tools should simply call toString() on the source object if the type is unfamiliar.

Specified by:

getSource in interface Element

getClassMatcher

public Matcher<? super java.lang.Class<?>> getClassMatcher()

getMethodMatcher

public Matcher<? super java.lang.reflect.Method> getMethodMatcher()

getInterceptors

public java.util.List<MethodInterceptor> getInterceptors()

acceptVisitor

public <T> T acceptVisitor(ElementVisitor<T> visitor)

Description copied from interface: Element

Accepts an element visitor. Invokes the visitor method specific to this element's type.

Specified by:

acceptVisitor in interface Element

Parameters:

visitor - to call back on

applyTo

public void applyTo(Binder binder)

Description copied from interface: Element

Writes this module element to the given binder (optional operation).

Specified by:

applyTo in interface Element

Parameters:

binder - to apply configuration element to
