Class WeakReferenceScopedResource<T>

java.lang.Object

net.openhft.chronicle.core.scoped.WeakReferenceScopedResource<T>

Type Parameters:

T - The type of the contained resource

All Implemented Interfaces:

Closeable, AutoCloseable, ScopedResource<T>

public class WeakReferenceScopedResource<T>
extends Object

A weak-referenced ScopedResource when the resource is acquired, we create a strong reference to prevent it being GC'd while it's "in use". Upon return, the strong reference is cleared, leaving only the weak reference thus allowing the resource to be GC'd.
