Method Details

newDependencyEdges

private <T extends Binding<?> & HasDependencies>
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

invalid reference

Key

.

Parameters:

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

binding - Binding for the dependencies

visit

public 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<Object,Collection<Edge>>

Overrides:

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

visit

public Collection<Edge> visit(ConvertedConstantBinding<?> binding)

Visitor for ConvertedConstantBinding. The Binding's

invalid reference

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<Object,Collection<Edge>>

Overrides:

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

visit

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

Visitor for InstanceBinding. We then render any dependency edgess that the instance may have, which come either from

invalid reference

InjectionPoint

s (method and field) on the instance, or on Dependencys the instance declares through the HasDependencies interface.

Specified by:

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

Overrides:

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

visit

public 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<Object,Collection<Edge>>

Overrides:

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

visit

public Collection<Edge> visit(ProviderBinding<?> binding)

Visitor for ProviderBinding. These Bindings arise from an

invalid reference

InjectionPoint

for the

invalid reference

Provider

interface.

Specified by:

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

Overrides:

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

visit

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

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

Specified by:

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

Overrides:

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

visit

public Collection<Edge> visit(ProviderKeyBinding<?> binding)

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

Specified by:

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

Overrides:

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

visitOther

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

Description copied from class: DefaultBindingTargetVisitor

Default visit implementation. Returns null.

Overrides:

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