Method Details

newInterfaceNode

private InterfaceNode newInterfaceNode(Binding<?> binding)

Returns a new interface node for the given Binding.

newImplementationNode

private ImplementationNode newImplementationNode(Binding<?> binding,
 Collection<Member> members)

Returns a new implementation node for the given binding.

Parameters:

binding - binding for the node to create

members - members to add to the node

Returns:

implementation node for the given binding

newInstanceNode

private <T extends Binding<?> & HasDependencies>
InstanceNode newInstanceNode(T binding,
 Object instance)

Returns a new instance node for the given Binding.

Parameters:

binding - binding for the node to create

instance - value of the instance

Returns:

instance node for the given binding

visit

public Collection<Node> visit(ConstructorBinding<?> binding)

Visitor for ConstructorBindings. These are for classes that Guice will instantiate to satisfy injection requests.

Specified by:

visit in interface BindingTargetVisitor<Object,Collection<Node>>

Overrides:

visit in class DefaultBindingTargetVisitor<Object,Collection<Node>>

visit

public Collection<Node> visit(InstanceBinding<?> binding)

Visitor for InstanceBinding. We render two nodes in this case: an interface node for the binding's Key, and then an implementation node for the instance Object itself.

Specified by:

visit in interface BindingTargetVisitor<Object,Collection<Node>>

Overrides:

visit in class DefaultBindingTargetVisitor<Object,Collection<Node>>

visit

public Collection<Node> visit(ProviderInstanceBinding<?> binding)

Same as visit(InstanceBinding), but the binding edge is BindingEdgeType#PROVIDER.

Specified by:

visit in interface BindingTargetVisitor<Object,Collection<Node>>

Overrides:

visit in class DefaultBindingTargetVisitor<Object,Collection<Node>>

visitOther

public Collection<Node> visitOther(Binding<?> binding)

Description copied from class: DefaultBindingTargetVisitor

Default visit implementation. Returns null.

Overrides:

visitOther in class DefaultBindingTargetVisitor<Object,Collection<Node>>
