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
