Method Detail

clone

public abstract java.lang.Object clone()

Returns a deep clone of this object.

Specified by:

clone in interface Unit

Overrides:

clone in class java.lang.Object

getUseBoxes

public java.util.List<ValueBox> getUseBoxes()

Returns a list of Boxes containing Values used in this Unit. The list of boxes is dynamically updated as the structure changes. Note that they are returned in usual evaluation order. (this is important for aggregation)

Specified by:

getUseBoxes in interface Unit

getDefBoxes

public java.util.List<ValueBox> getDefBoxes()

Returns a list of Boxes containing Values defined in this Unit. The list of boxes is dynamically updated as the structure changes.

Specified by:

getDefBoxes in interface Unit

getUnitBoxes

public java.util.List<UnitBox> getUnitBoxes()

Returns a list of Boxes containing Units defined in this Unit; typically branch targets. The list of boxes is dynamically updated as the structure changes.

Specified by:

getUnitBoxes in interface Unit

getBoxesPointingToThis

public java.util.List<UnitBox> getBoxesPointingToThis()

Returns a list of Boxes pointing to this Unit.

Specified by:

getBoxesPointingToThis in interface Unit

addBoxPointingToThis

public void addBoxPointingToThis(UnitBox b)

Description copied from interface: Unit

Adds a box to the list returned by getBoxesPointingToThis.

Specified by:

addBoxPointingToThis in interface Unit

removeBoxPointingToThis

public void removeBoxPointingToThis(UnitBox b)

Description copied from interface: Unit

Removes a box from the list returned by getBoxesPointingToThis.

Specified by:

removeBoxPointingToThis in interface Unit

clearUnitBoxes

public void clearUnitBoxes()

Description copied from interface: Unit

Clears any pointers to and from this Unit's UnitBoxes.

Specified by:

clearUnitBoxes in interface Unit

getUseAndDefBoxes

public java.util.List<ValueBox> getUseAndDefBoxes()

Returns a list of ValueBoxes, either used or defined in this Unit.

Specified by:

getUseAndDefBoxes in interface Unit

apply

public void apply(Switch sw)

Used to implement the Switchable construct.

Specified by:

apply in interface Switchable

redirectJumpsToThisTo

public void redirectJumpsToThisTo(Unit newLocation)

Description copied from interface: Unit

Redirects jumps to this Unit to newLocation. In general, you shouldn't have to use this directly.

Specified by:

redirectJumpsToThisTo in interface Unit
