- Constructor Detail
  - Initializer
```
public Initializer(Expression value)
```
    Constructs a new initializer with the specified initializing value.
    
    Parameters:
    value - the initializing value expression.
  - Initializer
```
public Initializer(Expression designator,
           Expression value)
```
    Constructs a new designated initializer with the given designator and the initial value.
    
    Parameters:
    designator - the designator for a member or an element.
    value - the initial value.
  - Initializer
```
public Initializer(java.util.List values)
```
    Constructs a new initializer with the specified list of values.
    
    Parameters:
    values - the list of initializing values.
  - Initializer
```
public Initializer(Expression designator,
           java.util.List values)
```
    Constructs a new initializer with the specified designator and the list of values.
    
    Parameters:
    designator - the designator for a member or an element.
    values - the list of initializing values.
- Method Detail
  - clone
```
public Initializer clone()
```
    Overrides:
    
    clone in class java.lang.Object
  - defaultPrint
```
public static void defaultPrint(Initializer i,
                java.io.PrintWriter o)
```
    Prints an initializer to the specified writer.
    
    Parameters:
    i - The initializer to print.
    o - The writer on which to print the initializer.
  - toString
```
public java.lang.String toString()
```
    Converts this initializer to a string by calling the default print method. All sub classes will be using this method unless specialized.
    
    Overrides:
    
    toString in class java.lang.Object
  - getChildren
```
public java.util.List<Traversable> getChildren()
```
    Description copied from interface: Traversable
    
    Provides access to the children of this object as a list. This object is free to internally implement its list as a LinkedList or an ArrayList. It is generally not good practice to call this method yourself; the ordering of children is not guaranteed so instead you should use the methods of the particular class whose children you wish to access.
    
    Specified by:
    
    getChildren in interface Traversable
    
    Returns:
    the children as a list.
  - getParent
```
public Traversable getParent()
```
    Description copied from interface: Traversable
    
    Provides access to the parent of this object. Every IR object has at most one parent. (The parent relationship is the same as the parent relationship in the parse tree, and is not to be confused with the base class of a derived class declaration.)
    
    Specified by:
    
    getParent in interface Traversable
    
    Returns:
    the parent of this object.
  - getDesignator
```
public Expression getDesignator()
```
  - print
```
public void print(java.io.PrintWriter o)
```
    Prints an initializer object by calling its default print method.
    
    Specified by:
    
    print in interface Printable
    
    Parameters:
    o - The writer on which to print the data.
  - removeChild
```
public void removeChild(Traversable child)
```
    Description copied from interface: Traversable
    
    Removes the specified child.
    
    Specified by:
    
    removeChild in interface Traversable
    
    Parameters:
    child - a reference to a child object that must match with ==.
  - setChild
```
public void setChild(int index,
            Traversable t)
```
    Description copied from interface: Traversable
    
    Sets the indexth child of this object to t. By calling this method, the old child located at the position i will have a null parent. It is generally not good practice to call this method yourself; the ordering of children is not guaranteed so instead you should use the methods of the particular class whose children you wish to access. There are checks to prevent such actions as making a statement a child of an expression, but you still may be able to do some damage with this method if you are not careful.
    
    Specified by:
    
    setChild in interface Traversable
  - setClassPrintMethod
```
public static void setClassPrintMethod(java.lang.reflect.Method m)
```
    Overrides the class print method, so that all subsequently created objects will use the supplied method.
    
    Parameters:
    m - The new print method.
  - setParent
```
public void setParent(Traversable t)
```
    Description copied from interface: Traversable
    
    Sets the parent of this object. Cetus checks that the parent already considers this object a child. The intent is to maintain an ordering where first this object becomes a child of another object, and then this object is told who its parent is. Enforcing this order makes it easier for Cetus to enforce other invariants and ensure the IR is correct.
    
    Specified by:
    
    setParent in interface Traversable
  - setPrintMethod
```
public void setPrintMethod(java.lang.reflect.Method m)
```
    Overrides the print method for this object only.
    
    Parameters:
    m - The new print method.
