Class SimpleByteCache

java.lang.Object

net.i2p.util.SimpleByteCache

public final class SimpleByteCache
extends Object

Like ByteCache but works directly with byte arrays, not ByteArrays. These are designed to be small caches, so there's no cleaner task like there is in ByteCache. And we don't zero out the arrays here. Only the static methods are public here.

Since:

0.8.3
