public abstract class BaseFwdCollator
extends java.text.RuleBasedCollator

The base class for a collator implementation using Progress-like rules for a specific character set.

Each code point in the character set is sorted uniquely and no allowances are made for varying collation strength. There are no ignorable characters.

Constructor Detail

BaseFwdCollator

BaseFwdCollator(java.lang.String cpName,
                int[] points)
         throws java.io.UnsupportedEncodingException,
                java.text.ParseException

The constructor. This class is constructed from within this package by the FwdCollatorProvider.

Parameters:

cpName - The name of this code page.

points - An array of bytes representing the order in which the code-points will be sorted.

Throws:

java.io.UnsupportedEncodingException - if there is an error generating the rules.

java.text.ParseException - if there is an error parsing the rules.

Method Detail

initRules

private static java.lang.String initRules(java.lang.String cpName,
                                          int[] points)
                                   throws java.io.UnsupportedEncodingException

Generate a rules string which governs Progress-like collation for the specific character set.

Parameters:

cpName - The name of this code page.

points - An array of bytes representing the order in which the code-points will be sorted.

Returns:

Rules string suitable for use by this rules-based collator.

Throws:

java.io.UnsupportedEncodingException - if the character encoding is unavailable.
