- Function
public class ContainsAllFunction
- extends StandardFunction
Returns true
if the array or collection in the first
argument contains all remaining arguments, in any order.
Usage: containsAll(a:array or list, element1, element2, ... elementN)
This function respects the value of
MathFunction.NULL_RETURNS_NULL
; if the array or list argument
is null
, the behavior is defined by the current value
of MathExpression.NULL_RETURNS_NULL. If the property is set to
true
, then a null
is returned. If the property
is set to false
, then false
is returned
(since null cannot contain anything).
