Field Detail

SORT_ORDER

static final String SORT_ORDER

An ISortOrder[] specifying an ordered list of IValueExpressions on which the sort will be imposed and the order (ascending or descending) for each IValueExpression.

VALUE_COMPARATOR

static final String VALUE_COMPARATOR

The Comparator used to compare individual as-bound / computed values within binding sets. This will be wrapped up with a comparator which knows how to compare the different values within the binding sets based on the declared SORT_ORDER.
