import java.util.LinkedHashMap;

 * Singleton class that implements "fast intern" functionality, essentially
 * adding a layer that caches Strings that have been previously intern()ed,
 * but that probably shouldn't be added to symbol tables.
 * This is usually used by improving intern()ing of things like namespace
 * URIs.
 * Note: that this class extends {@link LinkedHashMap} is an implementation
 * detail -- no code should ever directly call Map methods.
public final class InternCache extends LinkedHashMap<String,String>
     * Let's create cache big enough to usually have enough space for
     * all entries... (assuming NS URIs only)
    private final static int DEFAULT_SIZE = 64;

     * Let's limit to hash area size of 1024.
    private final static int MAX_SIZE = 660;

    private final static InternCache sInstance = new InternCache();

    private InternCache() {
        /* Let's also try to seriously minimize collisions... since
         * collisions are likely to be more costly here, with longer
         * Strings; so let's use 2/3 ratio (67%) instead of default
         * (75%)
        super(DEFAULT_SIZE, 0.6666f, false);
