use of com.servoy.j2db.scripting.IExecutingEnviroment in project servoy-client by Servoy.

the class JSDataSet method js_sort.

/**
 * Sort the dataset using the function as comparator.
 * The comparator function is called to compare two rows, that are passed as arguments, and
 * it will return -1/0/1 if the first row is less/equal/greater then the second row.
 *
 * NOTE: starting with 7.2 release, when called on datasource(foundset) dataset, this function doesn't save the data anymore
 *
 * @sample
 * //sort using comparator
 * dataset.sort(mySortFunction);
 *
 * function mySortFunction(r1, r2)
 * {
 *	var o = 0;
 *	if(r1[0] < r2[0])
 *	{
 *		o = -1;
 *	}
 *	else if(r1[0] > r2[0])
 *	{
 *		o = 1;
 *	}
 *	return o;
 * }
 *
 * @param comparator comparator function
