Method Summary

Stmt	codeGen(SootMethod method, LocalGeneratorEx localgen, Chain units, Stmt begin, Stmt fail, boolean sense, WeavingContext wc) Generate the code for this dynamic residue.
static Residue	construct(Residue left, Residue right) Smart constructor; some short-circuiting may need to be removed to mimic ajc behaviour
void	getAdviceFormalBindings(Residue.Bindings bindings, AndResidue andRoot) Fills the Bindings object with information of possible advice-formal bindings.
Residue	getLeftOp() Get the left operand
ResidueBox	getLeftOpBox() Get the left box

Residue	getRightOp() Get the right operand
ResidueBox	getRightOpBox() Get the right box
Residue	inline(ConstructorInliningMap cim) Make a copy of the residue applying to an inlined version of the code.
Residue	optimize() Optimize the residue by rebuilding it, invoking the smart constructors along the way.
Residue	resetForReweaving()
Residue	restructureToCreateBindingsMask(soot.Local bindingsMaskLocal, Residue.Bindings bindings) Returns residue that replaces the old residue.

Method Detail

optimize

public Residue optimize()

Description copied from class: Residue

Optimize the residue by rebuilding it, invoking the smart constructors along the way.

Specified by:

optimize in class Residue

inline

public Residue inline(ConstructorInliningMap cim)

Description copied from class: Residue

Make a copy of the residue applying to an inlined version of the code.

Specified by:

inline in class Residue

getLeftOp

public Residue getLeftOp()

Get the left operand

getRightOp

public Residue getRightOp()

Get the right operand

getLeftOpBox

public ResidueBox getLeftOpBox()

Get the left box

getRightOpBox

public ResidueBox getRightOpBox()

Get the right box

toString

public java.lang.String toString()

Description copied from class: Residue

Must provide a toString method

Specified by:

toString in class Residue

resetForReweaving

public Residue resetForReweaving()

Overrides:

resetForReweaving in class Residue

construct

public static Residue construct(Residue left,
                                Residue right)

Smart constructor; some short-circuiting may need to be removed to mimic ajc behaviour

codeGen

public Stmt codeGen(SootMethod method,
                    LocalGeneratorEx localgen,
                    Chain units,
                    Stmt begin,
                    Stmt fail,
                    boolean sense,
                    WeavingContext wc)

Description copied from class: Residue

Generate the code for this dynamic residue.

Specified by:

codeGen in class Residue

Parameters:

method - The method the code is being inserted into

localgen - A local generator for the method

units - The chain the code is being inserted into

begin - Code will be inserted just after this statement

fail - If the residue "fails", the inserted code will jump to this point; otherwise it will fall through

sense - If this is false, inverts the meaning of failure and success for the residue

wc - The weaving context

Returns:

The last statement that was inserted into the chain (or begin if nothing was).

getAdviceFormalBindings

public void getAdviceFormalBindings(Residue.Bindings bindings,
                                    AndResidue andRoot)

Description copied from class: Residue

Fills the Bindings object with information of possible advice-formal bindings. Has to be overwritten by all Residue classes that have children. andRoot is the outermost directly enclosing AndResidue (or null). (see implementation in AndResidue)

Overrides:

getAdviceFormalBindings in class Residue

restructureToCreateBindingsMask

public Residue restructureToCreateBindingsMask(soot.Local bindingsMaskLocal,
                                               Residue.Bindings bindings)

Description copied from class: Residue

Returns residue that replaces the old residue. This way, BindMaskResidue is inserted throughout the tree in the appropriate places. Has to be overridden by all Residue classes that have children.

Overrides:

restructureToCreateBindingsMask in class Residue

getResidueBoxes

public java.util.List getResidueBoxes()

Overrides:

getResidueBoxes in class Residue
