Methods Summary
java.util.Vector	getContractValues(int ch) Get the entry of hash table of the contracting string in the collation table. param ch the starting character of the contracting string int index = mapping.elementAt(ch); return getContractValuesImpl(index - CONTRACTCHARINDEX);
private java.util.Vector	getContractValuesImpl(int index) if (index >= 0) { return (Vector)contractTable.elementAt(index); } else // not found { return null; }
static final int	getEntry(java.util.Vector list, java.lang.String name, boolean fwd) for (int i = 0; i < list.size(); i++) { EntryPair pair = (EntryPair)list.elementAt(i); if (pair.fwd == fwd && pair.entryName.equals(name)) { return i; } } return UNMAPPED;
final int[]	getExpandValueList(int order) Get the entry of hash table of the expanding string in the collation table. param idx the index of the expanding string value list return (int[])expandTable.elementAt(order - EXPANDCHARINDEX);
int	getMaxExpansion(int order) Return the maximum length of any expansion sequences that end with the specified comparison order. param order a collation order returned by previous or next. return the maximum length of any expansion seuences ending with the specified order. see CollationElementIterator#getMaxExpansion int result = 1; if (expandTable != null) { // Right now this does a linear search through the entire // expandsion table. If a collator had a large number of expansions, // this could cause a performance problem, but in practise that // rarely happens for (int i = 0; i < expandTable.size(); i++) { int[] valueList = (int [])expandTable.elementAt(i); int length = valueList.length; if (length > result && valueList[length-1] == order) { result = length; } } } return result;
short	getMaxSecOrder() return maxSecOrder;
short	getMaxTerOrder() return maxTerOrder;
public java.lang.String	getRules() Gets the table-based rules for the collation object. return returns the collation rules that the table collation object was created from. return rules;
int	getUnicodeOrder(int ch) Get the comarison order of a character from the collation table. return the comparison order of a character. return mapping.elementAt(ch);
public boolean	isFrenchSec() return frenchSec;
public boolean	isSEAsianSwapping() return seAsianSwapping;
static void	reverse(java.lang.StringBuffer result, int from, int to) Reverse a string. int i = from; char swap; int j = to - 1; while (i < j) { swap = result.charAt(i); result.setCharAt(i, result.charAt(j)); result.setCharAt(j, swap); i++; j--; }
boolean	usedInContractSeq(int c) Returns true if this character appears anywhere in a contracting character sequence. (Used by CollationElementIterator.setOffset().) return contractFlags.get(c) == 1;
