public class ExpressionList extends List
LinkedList. The code that uses it looks
a little cleaner when casts are all taken care of automatically.| Modifier and Type | Class and Description |

|---|
ExpressionList()
Default constructor.
|
ExpressionList(Expression e)
Initializing constructor.
|
ExpressionList(Expression e,
ExpressionList l)
Initializing constructor.
|
| Modifier and Type | Method and Description |
|---|---|
void |
add(Expression e)
Adds another
Expression to the end of the list. |
void |
addAll(ExpressionList e)
Adds all the
Expressions in another ExpressionList to the end of
this ExpressionList. |
Object |
clone()
Creates a new object with the same primitive data, and recursively creates new member data
objects as well.
|
boolean |
containsQuantifiedVariable()
Determines if there are any quantified variables in this expression.
|
HashSet |
getVariableTypes()
Returns a set of
Arguments storing the name and type of each variable that is a
subexpression of this expression. |
ASTNodeIterator |
iterator()
Returns an iterator used to successively access the children of this node.
|
ExpressionList.ExpressionListIterator |
listIterator()
Returns an iterator used specifically to access the elements of this list.
|
void |
runPass(Pass pass)
Ensures that the correct
run() method is called for this type of node. |
Expression[] |
toArray()
Transforms the list into an array of expressions.
