Example 47 with Function

use of org.mozilla.javascript.Function in project servoy-client by Servoy.

the class FoundSet method sort.

/**
 * Sorts the foundset based on the given record comparator function.
 * Tries to preserve selection based on primary key. If first record is selected or cannot select old record it will select first record after sort.
 * The comparator function is called to compare
 * two records, that are passed as arguments, and
 * it will return -1/0/1 if the first record is less/equal/greater
 * then the second record.
 *
 * The function based sorting does not work with printing.
 * It is just a temporary in-memory sort.
 *
 * NOTE: starting with 7.2 release this function doesn't save the data anymore
 *
 * @sample
 * %%prefix%%foundset.sort(mySortFunction);
 *
 * function mySortFunction(r1, r2)
 * {
 *	var o = 0;
 *	if(r1.id < r2.id)
 *	{
 *		o = -1;
 *	}
 *	else if(r1.id > r2.id)
 *	{
 *		o = 1;
 *	}
 *	return o;
 * }
 *
 * @param recordComparisonFunction record comparator function
