Class CharsDeduplicator

java.lang.Object

org.threadly.load.CharsDeduplicator

public class CharsDeduplicator
extends java.lang.Object

Class used for de duplicating strings into a more minimal storage form. This does a more aggressive form of reference aggregation than String.intern(). And in fact the cache continues to grow infinitely until clearCache() is invoked.

The returned references are not Strings, but rather a reference which only holds the char[], all invocations then calculate the result at the time of invocation. Trading memory for extra CPU cycles.

Method Detail

public static LightCharSequence deDuplicate(java.lang.String str)

Returns:

Immutable CharSequence which represents the strings contents

clearCache

public static void clearCache()

Clears the stored cache, freeing up all stored memory here.
