Method Detail

getCacheSize

public static int getCacheSize()

Returns:

Returns the cacheSize.

setCacheSize

public static void setCacheSize(int cacheSize)

Parameters:

cacheSize - The cacheSize to set.

getByteEnabled

public static boolean getByteEnabled()

Returns:

Returns the enabled.

setByteEnabled

public static void setByteEnabled(boolean byteEnabled)

Parameters:

byteEnabled - The enabled to set.

getCharEnabled

public static boolean getCharEnabled()

Returns:

Returns the enabled.

setCharEnabled

public static void setCharEnabled(boolean charEnabled)

Parameters:

charEnabled - The enabled to set.

getTrainThreshold

public static int getTrainThreshold()

Returns the trainThreshold.

setTrainThreshold

public static void setTrainThreshold(int trainThreshold)

Parameters:

trainThreshold - The trainThreshold to set.

getAccessCount

public static int getAccessCount()

Returns:

getHitCount

public static int getHitCount()

Returns:

Returns the hitCount.

reset

public static void reset()

toString

public static String toString(ByteChunk bc)

toString

public static String toString(CharChunk cc)

compare

protected static int compare(ByteChunk name,
                             byte[] compareTo)

Compare given byte chunk with byte array. Return -1, 0 or +1 if inferior, equal, or superior to the String.

find

protected static String find(ByteChunk name)

Find an entry given its name in the cache and return the associated String.

findClosest

protected static int findClosest(ByteChunk name,
                                 StringCache.ByteEntry[] array,
                                 int len)

Find an entry given its name in a sorted array of map elements. This will return the index for the closest inferior or equal item in the given array.

compare

protected static int compare(CharChunk name,
                             char[] compareTo)

Compare given char chunk with char array. Return -1, 0 or +1 if inferior, equal, or superior to the String.

find

protected static String find(CharChunk name)

Find an entry given its name in the cache and return the associated String.

findClosest

protected static int findClosest(CharChunk name,
                                 StringCache.CharEntry[] array,
                                 int len)

Find an entry given its name in a sorted array of map elements. This will return the index for the closest inferior or equal item in the given array.
