pack-priv final Class MergeCollation

extends Object
Class Inheritance
Imports
java.util.ArrayList
Utility class for normalizing and merging patterns for collation. Patterns are strings of the form *, where has the form: := * := {"/"} := "=", ",", ";", "<", "&" , and are both arbitrary strings. unquoted whitespaces are ignored. 'xxx' can be used to quote characters One difference from Collator is that & is used to reset to a current point. Or, in other words, it introduces a new sequence which is to be added to the old. That is: "a < b < c < d" is the same as "a < b & b < c & c < d" OR "a < b < d & b < c" XXX: make '' be a single quote.
