Parameter

Parameter	Description
span	The span un the uncompressed grid. <code>LayoutUtil.INF</code> will be interpreted to span the rest of the column/row excluding the surrounding docking components.
indexes	The indexes in the correct dimension.

Return

The converted span.

Declaration

private static int convertSpanToSparseGrid(final int curIx, final int span, final TreeSet<Integer> indexes) 

Method Source Code

//package com.java2s;

import java.util.TreeSet;

public class Main {
    /**/*from   ww w. j  a va  2  s .  co m*/
     * Spanning is specified in the uncompressed grid number. They can for instance be more than 60000 for the outer
     * edge dock grid cells. When the grid is compressed and indexed after only the cells that area occupied the span
     * is erratic. This method use the row/col indexes and corrects the span to be correct for the compressed grid.
     * 
     * @param span The span un the uncompressed grid. <code>LayoutUtil.INF</code> will be interpreted to span the rest
     *            of the column/row excluding the surrounding docking components.
     * @param indexes The indexes in the correct dimension.
     * @return The converted span.
