Method Detail

visit

public java.util.Collection<Key<?>> visit(ConstructorBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a constructor binding. To resolve injections, an instance is instantiated by invoking constructor. This target is found only on injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(ConvertedConstantBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a binding created from converting a bound instance to a new type. The source binding has the same binding annotation but a different type. This target is found only on injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(InstanceBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a instance binding. The same instance is returned for every injection. This target is found in both module and injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(LinkedKeyBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a linked key binding. The other key's binding is used to resolve injections. This target is found in both module and injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(ProviderBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a binding to a Provider that delegates to the binding for the provided type. This target is found only on injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(ProviderInstanceBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a provider instance binding. The provider's get method is invoked to resolve injections. This target is found in both module and injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visit

public java.util.Collection<Key<?>> visit(ProviderKeyBinding<?> binding)

Description copied from interface: BindingTargetVisitor

Visit a provider key binding. To resolve injections, the provider key is first resolved, then that provider's get method is invoked. This target is found in both module and injector bindings.

Specified by:

visit in interface BindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

Overrides:

visit in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>

visitOther

public java.util.Collection<Key<?>> visitOther(Binding<?> binding)

Description copied from class: DefaultBindingTargetVisitor

Default visit implementation. Returns null.

Overrides:

visitOther in class DefaultBindingTargetVisitor<java.lang.Object,java.util.Collection<Key<?>>>
