Package com.google.monitoring.runtime.instrumentation

Interface ConstructorCallback<T>

Type Parameters:

T - The class that will be sampled with this ConstructorCallback

public interface ConstructorCallback<T>

This interface describes a function that is used to sample a constructor. It is intended to be invoked every time a constructor for class T is invoked. This will not be invoked when subclasses of T are instantiated. This mechanism works independently of whether the class is part of the JDK core library.

Method Summary

Modifier and Type	Method	Description
void	sample(T newObj)	When an object implementing interface ConstructorCallback is passed to ConstructorInstrumenter.instrumentClass(Class, ConstructorCallback), it will get executed whenever a constructor for type T is invoked.

Method Detail

sample

void sample(T newObj)

When an object implementing interface ConstructorCallback is passed to ConstructorInstrumenter.instrumentClass(Class, ConstructorCallback), it will get executed whenever a constructor for type T is invoked.

Parameters:

newObj - the new Object whose construction we're recording. The object is not fully constructed; any references to this object that are stored in this callback are subject to the memory model constraints related to such objects.
