java.lang.Cloneable
@Deprecated public final class CompactByteArray extends java.lang.Object implements java.lang.Cloneable
Deprecated.This API is ICU internal only.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.
