Class FromStringInterner<T>

java.lang.Object

net.openhft.chronicle.wire.internal.FromStringInterner<T>

public abstract class FromStringInterner<T>
extends Object

This cache only gaurentees it will provide a String which matches the decoded bytes.

It doesn't guantee it will always return the same object, nor that different threads will return the same object, though the contents should always be the same.

While not technically thread safe, it should still behave correctly.
