Constructor Detail

RenamedVariableDecl

public RenamedVariableDecl(java.lang.String name,
                           VariableDecl original)

Parameters:

name - is the new name (should be based on the original name)

original - is the variable that this variable was renamed from

See Also:

SSA

Method Detail

finalize

protected void finalize()
                 throws java.lang.Throwable

Keep the count of instances up-to-date.

Overrides:

finalize in class VariableDecl

Throws:

java.lang.Throwable - [needs description]

number

public static int number()

Return the current number of instances of this class.

created

public static int created()

Return the number of instances of this class created.

visit

public void visit(Predicate p)

Description copied from class: Node

The visit() method is used to implement a visit 'pattern'.

Overrides:

visit in class VariableDecl

getOriginal

public VariableDecl getOriginal()

Return the variable that this variable was renamed from.

Overrides:

getOriginal in class VariableDecl

addressTaken

public boolean addressTaken()

Return true if the address of this Declaration has been taken.

Overrides:

addressTaken in class VariableDecl

isVirtual

public boolean isVirtual()

Return true if the declaration is a virtual variable.

Overrides:

isVirtual in class Declaration

createChildren

protected Vector createChildren()

Description copied from class: Node

Create the list of children for the node - each node that has children must implement this method. However, use getChildren() to actually get the children.

Overrides:

createChildren in class ValueDecl

Following copied from class: scale.clef.Node

Returns:

the list of children
