  - getSymbol
```
public Var getSymbol()
```
    Description copied from interface: StaticRef
    
    The variable that this reference points to.

    getSymbol in interface StaticRef
  - getNode
```
public Node getNode()
```
    Description copied from interface: StaticRef
    
    The node where the reference lives.
    
    Specified by:
    
    getNode in interface StaticRef
  - getInputId
```
public InputId getInputId()
```
  - getSourceFile
```
public StaticSourceFile getSourceFile()
```
    Description copied from interface: StaticRef
    
    The source file where the reference lives.
    
    Specified by:
    
    getSourceFile in interface StaticRef
  - isVarDeclaration
```
public boolean isVarDeclaration()
```
  - isConstDeclaration
```
public boolean isConstDeclaration()
```
  - isInitializingDeclaration
```
public boolean isInitializingDeclaration()
```
    Determines whether the variable is initialized at the declaration.
  - isSimpleAssignmentToName
```
public boolean isSimpleAssignmentToName()
```
  - isLvalue
```
public boolean isLvalue()
```
    Returns whether the name node for this reference is an lvalue. TODO(tbreisacher): This method disagrees with NodeUtil#isLValue for "var x;" and "let x;". Consider updating it to match.
