A cardinality that describes the optional range from 0 to 1 with default 0.

MANDATORY

Constructor Detail

CardinalityRange

public CardinalityRange(Integer lower,
                        Integer upper,
                        Integer def)

Constructs a CardinalityRange with the given lower and upper bounds as well as the given default value. The default value must be in between the lower and upper bound or equal to one of them (though not Integer.MAX_VALUE).

Parameters:

lower - the lowest possible cardinality

upper - the highest possible cardinality

def - the default cardinality, must be in between or equal to one of the bounds

Throws:

IllegalArgumentException - if the default value is not in the range.
