    public java.lang.String getName()

Description copied from interface: `Variable`
the name of the variable

Specified by:
  `getName` in interface `Variable`

#### getType

    public ClassNode getType()

Description copied from interface: `Variable`
the type of the variable

Specified by:
  `getType` in interface `Variable`

#### setType

    public void setType(ClassNode type)

#### hasInitialExpression

    public boolean hasInitialExpression()

Description copied from interface: `Variable`
returns true if there is an initialization expression

Specified by:

    public Expression getInitialExpression()

Description copied from interface: `Variable`
expression used to initialize the variable or null of there is no initialization.

Specified by:
  `getInitialExpression` in interface `Variable`
Returns:
