    • Method Detail

      • getEmptyRoleSemantic

        public ServletSecurity.EmptyRoleSemantic getEmptyRoleSemantic()
        Gets the default authorization semantic.

        This value is insignificant when getRolesAllowed returns a non-empty array, and should not be specified when a non-empty array is specified for getRolesAllowed.

        Returns:
        the ServletSecurity.EmptyRoleSemantic to be applied when getRolesAllowed returns an empty (that is, zero-length) array

      • getTransportGuarantee

        public ServletSecurity.TransportGuarantee getTransportGuarantee()
        Gets the data protection requirement (i.e., whether or not SSL/TLS is required) that must be satisfied by the transport connection.
        Returns:
        the ServletSecurity.TransportGuarantee indicating the data protection that must be provided by the connection

      • getRolesAllowed

        public String[] getRolesAllowed()
        Gets the names of the authorized roles.

        Duplicate role names appearing in getRolesAllowed are insignificant and may be discarded. The String "*" has no special meaning as a role name (should it occur in getRolesAllowed).

        Returns:
        a (possibly empty) array of role names. When the array is empty, its meaning depends on the value of getEmptyRoleSemantic(). If its value is DENY, and getRolesAllowed returns an empty array, access is to be denied independent of authentication state and identity. Conversely, if its value is PERMIT, it indicates that access is to be allowed independent of authentication state and identity. When the array contains the names of one or more roles, it indicates that access is contingent on membership in at least one of the named roles (independent of the value of getEmptyRoleSemantic()).
