public class ConstantList
extends List

Currently, this is just a wrapper class for LinkedList. The code that uses it looks a little cleaner when casts are all taken care of automatically.

Constructor Detail

ConstantList

public ConstantList()

Default constructor.

ConstantList

public ConstantList(Constant c)

Initializing constructor. Requires its argument to be non-null.

Parameters:

c - A single Constant with which to initialize this list.

ConstantList

public ConstantList(String[] a)

Creates an entire list from an array of values.

Parameters:

a - The array of constant values.

ConstantList

public ConstantList(ByteString[] a)

Creates an entire list from an array of values.

Parameters:

a - The array of constant values.

Method Detail

add

public void add(Constant c)

Adds another Constant to the end of the list.

Parameters:

c - A reference to the Constant to be added.

addAll

public void addAll(ConstantList l)

Adds all the Constants in another ConstantList to the end of this ConstantList.

Parameters:

l - The list to be added.

toArray

public Constant[] toArray()

Transforms the list into an array of expressions.

Returns:

An array of constants containing references to every constant in the list.

equals

public boolean equals(Object o)

Two ConstantLists are equal when they contain the same elements in the same order as evaluated by the Constant.equals(Object) method.

Overrides:

equals in class List

Parameters:

o - The object to test equality with.

Returns:

true iff this ConstantList is equivalent to the specified object as described above.

hashCode

public int hashCode()

A hash code based on the hash codes of the elements of the list.

Overrides:

hashCode in class List

listIterator

public ConstantList.ConstantListIterator listIterator()

Returns an iterator used specifically to access the elements of this list.

Returns:

An iterator used specifically to access the elements of this list.

iterator

public ASTNodeIterator iterator()

Returns an iterator used to successively access the children of this node.

Specified by:

iterator in class ASTNode

Returns:

An iterator used to successively access the children of this node.

clone

public Object clone()

Creates a new object with the same primitive data, and recursively creates new member data objects as well.

Overrides:

clone in class ASTNode

Returns:

The clone node.

runPass

public void runPass(Pass pass)

Ensures that the correct run() method is called for this type of node.

Specified by:

runPass in class ASTNode

Parameters:

pass - The pass whose run() method should be called.
