      • NON_EXISTENT

        public static final StreamingData.Punctuation NON_EXISTENT
        No punctuation, will be ignored by StreamingOutput.punctuate().

      • FINAL_MARKER

        public static final StreamingData.Punctuation FINAL_MARKER
        Mark representing no more tuples or punctuation will be handled by a port.

        Once a FINAL_MARKER is received for an input port, the operator will not receive any further calls to its process and processPunctuation for that input port (StreamingInput instance).

        After an operator submits a FINAL_MARKER to an output port, any tuples or punctuation marks submitted to that port are silently discarded.

      • values

        public static StreamingData.Punctuation[] 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 (StreamingData.Punctuation c : StreamingData.Punctuation.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static StreamingData.Punctuation 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
