- - ### Element Detail

    - #### value

          public abstract java.lang.String value

      HTTP Protocol method name (e.g. POST, PUT)
      Returns:
        method name

    - #### emptyRoleSemantic

          public abstract ServletSecurity.EmptyRoleSemantic emptyRoleSemantic

      The EmptyRoleSemantic determines the behaviour when the rolesAllowed list is empty.
      Returns:
        empty role semantic
      Default:
        javax.servlet.annotation.ServletSecurity.EmptyRoleSemantic.PERMIT

    - #### transportGuarantee

          public abstract ServletSecurity.TransportGuarantee transportGuarantee

      Determines whether SSL/TLS is required to process the current request.
      Returns:
        transport guarantee
      Default:
        javax.servlet.annotation.ServletSecurity.TransportGuarantee.NONE

    - #### rolesAllowed

          public abstract java.lang.String[] rolesAllowed

      The authorized roles' names. The container may discard duplicate role names during processing of the annotation. N.B. The String "*" does not have a special meaning if it occurs as a role name.
      Returns:
        array of names. The array may be of zero length, in which case the EmptyRoleSemantic applies; the returned value determines whether access is to be permitted or denied regardless of the identity and authentication state in either case, PERMIT or DENY.
        Otherwise, when the array contains one or more role names access is permitted if the user a member of at least one of the named roles. The EmptyRoleSemantic is not applied in this case.
      Default:
        {}
