Interface ProvisionMetrics

All Known Implementing Classes:

NullProvisionMetrics, SimpleProvisionMetrics

public interface ProvisionMetrics

Interface invoked by LifecycleModule's ProvisionListener to gather metrics on objects as they are provisioned. Through the provision listener it's possible to generate a dependency tree for the first initialization of all objects. Note that no call will be made for singletons that are being injected but have already been instantiated.

Methods

Modifier and Type	Method and Description
void	accept(ProvisionMetrics.Visitor visitor) Traverse the elements using the visitor pattern.
void	pop() Pop and finalize initialization of the latest object to be provisioned.
void	push(com.google.inject.Key<?> key) Notification that an object of type 'key' is about to be created.

Method Detail

push

void push(com.google.inject.Key<?> key)

Notification that an object of type 'key' is about to be created. Note that there will likely be several nested calls to push() as dependencies are injected.

Parameters:

key -

pop

void pop()

Pop and finalize initialization of the latest object to be provisioned. A matching pop will be called for each push().

accept

void accept(ProvisionMetrics.Visitor visitor)

Traverse the elements using the visitor pattern.

Parameters:

visitor -
