public class MustOccurConstraint
extends BaseConstraint

Must occur constraints are constraints that indicate some range of acceptable valid results. So a must occur constraint might indicate that between 1 and 3 prequisite constraints must be valid. For example, on a person object, it might be that one of three fields must be filled in: 1. username 2. email 3. phone number By imposing a must occur constraint on the person object iself, and setting three prequisite constraints below it, with a min of 1 and a max of 3, this requirement can be enforced. A more complicated example might be that a US address is only valid if it provides either: (a) a city and state, or (b) a postal code To enforce this, a single must occur constraint would have two children: (1) a prequisite constraint on postal code, and (2) a must occur constraint with two child prequisite constraints, on city and state, respectively. By setting min=1/max=2 at the top must occur constraint, and min=2/max=2 at the leaf constraint, this requirement can be enforced.

public String getLabelKey()

Description copied from class: BaseConstraint

LabelKey should be a single word key. This key is used to find a message to use for this constraint from available messages. The key is also used for defining/retrieving validation method names when applicable for ValidCharactersContraints. If a comma separated list of keys is used, a message will be generated that is a comma separated list of the messages retrieved for each key.
