- Method Detail
  - values
```
public static BuiltinFunction[] 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 (BuiltinFunction c : BuiltinFunction.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static BuiltinFunction 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
  - forFunctionName
```
public static BuiltinFunction forFunctionName(String functionName)
```
    Returns the NonpluginFunction for the given function name, or null if not found.
    
    Parameters:
    functionName - The function name to retrieve.
  - getName
```
public String getName()
```
    Description copied from interface: SoyFunction
    
    Gets the name of the Soy function.
    
    Specified by:
    
    getName in interface SoyFunction
    
    Returns:
    The name of the Soy function.
  - getValidArgsSizes
```
public Set<Integer> getValidArgsSizes()
```
    Description copied from interface: SoyFunction
    
    Gets the set of valid args list sizes. For example, the set {0, 2} would indicate that this function can take 0 or 2 arguments (but not 1).
    
    Specified by:
    
    getValidArgsSizes in interface SoyFunction
    
    Returns:
    The set of valid args list sizes.
