```
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
  - createOperatorNode
```
public static final ExprNode.OperatorNode createOperatorNode(SourceLocation location,
                                                             String op,
                                                             int prec,
                                                             ExprNode... children)
```
    Create an operator node, given the token, precedence, and list of children (arguments).
    
    Parameters:
    
    op - A string listing the operator token. If multiple tokens (e.g. the ternary conditional operator), separate them using a space.
    
    prec - The precedence of an operator. Must match the precedence specified by op.
    
    children - The list of children (arguments) for the operator.
    
    Returns:
    
    The matching OperatorNode.
    
    Throws:
    
    IllegalArgumentException - If there is no Soy operator matching the given data.
  - getSyntax
```
public List<Operator.SyntaxElement> getSyntax()
```
    Returns the canonical syntax for this operator, including spacing.
  - getTokenString
```
public String getTokenString()
```
    Returns this operator's token. Multiple tokens (e.g. the ternary conditional operator) are separated using a space.
  - getNumOperands
```
public int getNumOperands()
```
    Returns the number of operands that this operator takes.
  - getPrecedence
```
public int getPrecedence()
```
    Returns this operator's precedence level.
  - getAssociativity
```
public Operator.Associativity getAssociativity()
```
    Returns this operator's associativity.
  - getDescription
```
public String getDescription()
```
    Returns a short description of this operator (usually just the token string).
  - createNode
```
public abstract ExprNode.OperatorNode createNode(SourceLocation location)
```
    Creates a node representing this operator.
  - createNode
```
public final ExprNode.OperatorNode createNode(SourceLocation location,
                                              ExprNode... children)
```
    Creates a node representing this operator, with the given children.
