Class PropsVectors

java.lang.Object

com.ibm.icu.impl.PropsVectors

public class PropsVectors
extends Object

Unicode Properties Vectors associated with code point ranges. Rows of primitive integers in a contiguous array store the range limits and the properties vectors. In each row, row[0] contains the start code point and row[1] contains the limit code point, which is the start of the next range. Initially, there is only one range [0..0x110000] with values 0. It would be possible to store only one range boundary per row, but self-contained rows allow to later sort them by contents.
