Class SecurityConstraint

  • All Implemented Interfaces:
    java.io.Serializable
    public class SecurityConstraint
extends XmlEncodingBase
implements java.io.Serializable
    Representation of a security constraint element for a web application, as represented in a <security-constraint> element in the deployment descriptor.

    WARNING: It is assumed that instances of this class will be created and modified only within the context of a single thread, before the instance is made visible to the remainder of the application. After that, only read access is expected. Therefore, none of the read and write access within this class is synchronized.

        the user constraint

      • setUserConstraint

        public void setUserConstraint​(java.lang.String userConstraint)
        Set the user data constraint for this security constraint.
        Parameters:
        userConstraint - The new user data constraint

      • treatAllAuthenticatedUsersAsApplicationRole

        public void treatAllAuthenticatedUsersAsApplicationRole()
        Called in the unlikely event that an application defines a role named "**".

      • addAuthRole

        public void addAuthRole​(java.lang.String authRole)
        Add an authorization role, which is a role name that will be permitted access to the resources protected by this security constraint.
        Parameters:
        authRole - Role name to be added

      • addCollection

        public void addCollection​(SecurityCollection collection)
        Add a new web resource collection to those protected by this security constraint.
