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.

Deprecated.

This API is ICU internal only.

Get the mapped value of a Unicode character.

Parameters:

index - the character to get the mapped value with
