Method Detail
- values
```
public static Op[] 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 (Op c : Op.values())
    System.out.println(c);
```
  Returns:
  
  an array containing the constants of this enum type, in the order they are declared
- valueOf
```
public static Op 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
- getArity
```
public int getArity()
```
  Get the arity of this symbol.
  
  Returns:
  
  symbol arity
- getSymbol
```
public String getSymbol()
```
  Get the symbol associated with this operator.
  
  Returns:
  
  operator symbol
- apply
```
public Value apply(ParseSession session,
                   Value... args)
```
  Apply this operator to the given parameters.
  
  Parameters:
  
  session - current session
  
  args - operator arguments
  
  Returns:
  
  result of operation
  
  Throws:
  
  IllegalArgumentException - if args contains inappropriate value(s)
  
  IllegalArgumentException - if the length of args does not match this operator
- forSymbol
```
public static Op forSymbol(String symbol)
```
  Get the Op corresponding to the given symbol. Note: some symbols correspond to multiple Ops:
  - For + or -, the binary operator is returned
  - For ++ or --, the post-increment operator is returned
  Parameters:
  
  symbol - symbol
  
  Returns:
  
  corresponding operator
  
  Throws:
  
  IllegalArgumentException - if no such Op exists
