public final Class BufferRecycler

Class Inheritance

extends Object

java.lang.Object
com.ning.compress.BufferRecycler

Imports

java.lang.ref.SoftReference

Simple helper class to encapsulate details of basic buffer recycling scheme, which helps a lot (as per profiling) for smaller encoding cases.
