Method Detail

newDependencyEdges

private <T extends Binding<?> & HasDependencies> java.util.Collection<Edge> newDependencyEdges(NodeId nodeId,
                                                                                               T binding)

Returns a dependency edge for each Dependency in the binding. These will be from the given node ID to the Dependency's Key.

Parameters:

nodeId - ID of the node that should be the tail of the dependency edges

binding - Binding for the dependencies

visit

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

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

Specified by:

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

Overrides:

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

visit

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

Visitor for ConvertedConstantBinding. The Binding's Key will be of an annotated primitive type, and the value of ConvertedConstantBinding.getSourceKey() will be of a String with the same annotation.

Specified by:

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

Overrides:

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

visit

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

Visitor for InstanceBinding. We then render any dependency edgess that the instance may have, which come either from InjectionPoints (method and field) on the instance, or on Dependencys the instance declares through the HasDependencies interface.

Specified by:

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

Overrides:

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

visit

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

Visitor for LinkedKeyBinding. This is the standard Binding you get from binding an interface class to an implementation class. We draw a BindingEdge from the interface node to the node of the implementing class.

Specified by:

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

Overrides:

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

visit

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

Visitor for ProviderBinding. These Bindings arise from an InjectionPoint for the Provider interface.

Specified by:

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

Overrides:

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

visit

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

Same as visit(InstanceBinding), but the binding edge is BindingEdge.Type.PROVIDER.

Specified by:

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

Overrides:

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

visit

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

Same as visit(LinkedKeyBinding), but the binding edge is BindingEdge.Type.PROVIDER.

Specified by:

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

Overrides:

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

visitOther

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

Description copied from class: DefaultBindingTargetVisitor

Default visit implementation. Returns null.

Overrides:

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