pack-priv final Class RBCollationTables

extends Object
Class Inheritance
Imports
java.util.Vector, sun.text.UCompactIntArray, .IntHashtable
This class contains the static state of a RuleBasedCollator: The various tables that are used by the collation routines. Several RuleBasedCollators can share a single RBCollationTables object, easing memory requirements and improving performance.

Constructor Detail

BuildAPIback to summary
private BuildAPI()

Private constructor. Prevents anyone else besides RBTableBuilder from gaining direct access to the internals of this class.

Method Detail

fillInTablesback to summary
pack-priv void fillInTables(boolean f2ary, boolean swap, UCompactIntArray map, Vector<Vector<EntryPair>> cTbl, Vector<int[]> eTbl, IntHashtable cFlgs, short mso, short mto)

This function is used by RBTableBuilder to fill in all the members of this object. (Effectively, the builder class functions as a "friend" of this class, but to avoid changing too much of the logic, it carries around "shadow" copies of all these variables until the end of the build process and then copies them en masse into the actual tables object once all the construction logic is complete. This function does that "copying en masse".

Parameters
f2ary:boolean

The value for frenchSec (the French-secondary flag)

swap:boolean

The value for SE Asian swapping rule

map:UCompactIntArray

The collator's character-mapping table (the value for mapping)

cTbl:Vector<Vector<EntryPair>>

The collator's contracting-character table (the value for contractTable)

eTbl:Vector<int[]>

The collator's expanding-character table (the value for expandTable)

cFlgs:IntHashtable

The hash table of characters that participate in contracting- character sequences (the value for contractFlags)

mso:short

The value for maxSecOrder

mto:short

The value for maxTerOrder
