Enum LoopFormState

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      ITERATION
      Only enough state to iterate over the source values is stored.
      NONE
      No state of any kind is stored, as if the Loop was not contained within a Form.
      VALUES
      Stores a sequence of values (obtained via a ValueEncoder) into the Form state.

      static LoopFormState valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.
      static LoopFormState[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

      • NONE

        public static final LoopFormState NONE
        No state of any kind is stored, as if the Loop was not contained within a Form.

      • ITERATION

        public static final LoopFormState ITERATION
        Only enough state to iterate over the source values is stored. When the Form is submitted, the Loop will re-acquire its source and iterate over it. This is equivalent to "volatile" mode in Tapestry 5.0. This can be subject to race conditions when the values within the source change between render and submit.

      • VALUES

        public static final LoopFormState VALUES
        Stores a sequence of values (obtained via a ValueEncoder) into the Form state. The source parameter is not re-acquired when the Form is submitted.

    • Method Detail

      • values

        public static LoopFormState[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (LoopFormState c : LoopFormState.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static LoopFormState valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
