      • values

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

      • valueOf

        public static Operator 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

      • writeTo

        public void writeTo​(java.io.DataOutput output)
             throws java.io.IOException
        Write the serialized version of this Operator to the specified output.
        Parameters:
        output - the output to write to
        Throws:
        java.io.IOException - if an I/O problem occurs while writing to the specified output

      • getValue

        public int getValue()

      • readFrom

        public static Operator readFrom​(java.io.DataInput input)
                         throws java.io.IOException
        Deserializes a Operator instance from the specified input.
        Parameters:
        input - the input to read from
        Returns:
        the Operator instance deserialized
        Throws:
        java.io.IOException - if a problem occurs while deserializing the Type instance.

      • isSatisfiedBy

                                      java.nio.ByteBuffer leftOperand,
                                      java.nio.ByteBuffer rightOperand)
        Whether 2 values satisfy this operator (given the type they should be compared with).

      • serializedSize

        public int serializedSize()

      • isContains

        public boolean isContains()
        Checks if this operator is CONTAINS operator.
        Returns:
