- Method Detail
  - getName
```
IdentifierTree getName()
```
    Returns the name of the function being declared.
    
    Returns:
    
    name the function declared
  - getParameters
```
List<? extends ExpressionTree> getParameters()
```
    Returns the parameters of this function.
    
    Returns:
    
    the list of parameters
  - getBody
```
Tree getBody()
```
    Returns the body of this function. This may be a BlockTree when this function has a block body. This is an ExpressionTree when the function body is a concise expression as in an expression arrow, or in an expression closure.
    
    Returns:
    
    the body of this function
  - isStrict
```
boolean isStrict()
```
    Is this a strict function?
    
    Returns:
    
    true if this function is strict
  - isArrow
```
boolean isArrow()
```
    Is this a arrow function?
    
    Returns:
    
    true if this is a arrow function
  - isGenerator
```
boolean isGenerator()
```
    Is this a generator function?
    
    Returns:
    
    true if this is a generator function
