Method Detail

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

resetForReweaving

public Residue resetForReweaving()

Overrides:

resetForReweaving in class Residue

construct

public static Residue construct(ContextValue value,
                                Type type,
                                WeavingVar variable)

toString

public java.lang.String toString()

Description copied from class: Residue

Must provide a toString method

Specified by:

toString in class Residue

getAdviceFormalBindings

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

If this Bind binds an advice-formal, add the binding to the Bindings object

Overrides:

getAdviceFormalBindings in class Residue

restructureToCreateBindingsMask

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

Replace this Bind with a BindMaskResidue containing this Bind if appropriate.

Overrides:

restructureToCreateBindingsMask in class Residue

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).

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
