 package org.apache.poi.hslf.model.textproperties;

Definition of a special kind of property of some text, or its paragraph. For these properties, a flag in the "contains" header field tells you the data property family will exist. The value of the property is itself a mask, encoding several different (but related) properties
 public class BitMaskTextProp extends TextProp implements Cloneable {
 	private String[] subPropNames;
 	private int[] subPropMasks;
 	private boolean[] subPropMatches;

Fetch the list of the names of the sub properties
 	public String[] getSubPropNames() { return ; }
Fetch the list of if the sub properties match or not
 	public boolean[] getSubPropMatches() { return ; }
 	public BitMaskTextProp(int sizeOfDataBlockint maskInHeaderString overallNameString[] subPropNames) {

 		// Initialise the masks list
 		for(int i=0; i<.i++) {
 			[i] = (1 << i);

As we're purely mask based, just set flags for stuff that is set
 	public int getWriteMask() {

Set the value of the text property, and recompute the sub properties based on it
 	public void setValue(int val) { 
 		 = val;
 		// Figure out the values of the sub properties
 		for(int i=0; i.i++) {

 				[i] = true;

Fetch the true/false status of the subproperty with the given index
 	public boolean getSubValue(int idx) {
 		return [idx];

Set the true/false status of the subproperty with the given index
 	public void setSubValue(boolean valueint idx) {
 		if([idx] == value) { return; }
 		if(value) {
