com.ibm.icu.util.CompactByteArray
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. @see CompactCharArray @author Helena Shih @internal @deprecated This API is ICU internal only.
