CompactCharArray
final public class CompactCharArray implements Cloneable(Code)
class CompactATypeArray : use only on primitive data types Provides a compact way to store information that is indexed by Unicode values, such as character properties, types, keyboard values, etc.This is very useful when you have a block of Unicode data that contains significant values while the rest of the Unicode data is unused in the application or when you have a lot of redundance, such as where all 21,000 Han ideographs have the same value. However, lookup is much faster than a hash table. A compact array of any primitive data type serves two purposes:
  • Fast access of the indexed values.
  • Smaller memory footprint.
A compact array is composed of a index array and value array. The index array contains the indicies of Unicode characters to the value array.

Method Detail
arrayRegionMatches
final static boolean arrayRegionMatches(char[] source, int sourceStart, char[] target, int targetStart, int len)(Code)
Convenience utility to compare two arrays of doubles.
Parameters:
  len - the length to compare.The start indices and start+len must be valid.



clone
public Object clone()(Code)
Overrides Cloneable



compact
public void compact()(Code)
Compact the array



compact
public void compact(boolean exhaustive)(Code)
Compact the array.



elementAt
public char elementAt(char index)(Code)
Get the mapped value of a Unicode character.
Parameters:
  index - the character to get the mapped value with the mapped value of the given character



equals
public boolean equals(Object obj)(Code)
Compares the equality of two compact array objects.
Parameters:
