@Deprecated public final class CompactCharArray extends Object implements Cloneable
Deprecated.

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 indices of Unicode characters to the value array.
