Examples with Validator org.apache.directory.fortress.core.util.time.Validator used on opensource projects

Example 1 with Validator

use of org.apache.directory.fortress.core.util.time.Validator in project directory-fortress-core by apache.

the class VUtil method validateConstraints.

/**
 * This utility iterates over all of the Validators initialized for runtime and calls them passing the {@link org.apache.directory.fortress.core.model.Constraint} contained within the
 * targeted entity.  If a particular {@link org.apache.directory.fortress.core.model.UserRole} violates constraint it will not be activated.  If {@link org.apache.directory.fortress.core.model.User} validation fails a ValidationException will be thrown thus preventing User logon.
 *
 * @param session contains {@link org.apache.directory.fortress.core.model.User} and {@link org.apache.directory.fortress.core.model.UserRole} constraints {@link org.apache.directory.fortress.core.model.Constraint} to be checked.
 * @param type    specifies User {@link ConstraintType#USER} or rOLE {@link ConstraintType#ROLE}.
 * @param checkDsd will check DSD constraints if true
 * @throws org.apache.directory.fortress.core.SecurityException in the event validation fails for User or system error occurs.
