                    java.util.List vars)

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

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

resetForReweaving

public Residue resetForReweaving()

Overrides:

resetForReweaving in class Residue

debug

public static void debug(java.lang.String message)

getIsValidStmt

public Stmt getIsValidStmt()

Returns the statement that was woven to test isValid().

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).

toString

public java.lang.String toString()

Description copied from class: Residue

Must provide a toString method

Specified by:

toString in class Residue

setup

public CflowSetup setup()
