Method Detail

### 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(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:
    `IllegalArgumentException` - if this enum type has no constant with the specified name
    `NullPointerException` - if the argument is null

### symbol

    public String symbol()

  Get the symbol for this operator

  Returns:
    the symbolic representation; never null

### reverse

    public Operator reverse()

  Get the equivalent operator if the operands are to be reversed.

  Returns:
    the reverse operator; never null

### isRangeOperator

    public boolean isRangeOperator()

  Determine whether this operator is one that is used to define a range of values: `<`, `>`, `<=`, or `>=`.

  Returns:
    true if this operator is a range operator, or false otherwise

### toString

    public String toString()

  Overrides:
    `toString` in class `Enum<Operator>`
  See Also:
    `Enum.toString()`

### forSymbol

    public static Operator forSymbol(String symbol)

  Attempt to find the Operator given a symbol. The matching is done independent of case.

  Parameters:
    `symbol` - the symbol
  Returns:
    the Operator having the supplied symbol, or null if there is no Operator with the supplied symbol
  Throws:
    `IllegalArgumentException` - if the symbol is null
