DavaFlowSet	newInitialFlow()
DavaFlowSet	processStatement(Stmt s, DavaFlowSet inSet) Specific stmts within AST Constructs are processed through this method.
DavaFlowSet	processSwitchKey(Value key, DavaFlowSet input) Deal with the key in the switch construct
DavaFlowSet	processSynchronizedLocal(Local local, DavaFlowSet input) To deal with the local used for synch blocks
DavaFlowSet	processUnaryBinaryCondition(ASTUnaryBinaryCondition cond, DavaFlowSet input) To have maximum flexibility in analyzing conditions the analysis API breaks down the aggregated conditions to simple unary or binary conditions user defined code can then deal with each condition separately.

Method Detail

emptyFlowSet

public DavaFlowSet emptyFlowSet()

Specified by:

emptyFlowSet in class StructuredAnalysis

setMergeType

public void setMergeType()

Specified by:

setMergeType in class StructuredAnalysis

newInitialFlow

public DavaFlowSet newInitialFlow()

Specified by:

newInitialFlow in class StructuredAnalysis

cloneFlowSet

public DavaFlowSet cloneFlowSet(DavaFlowSet flowSet)

Description copied from class: StructuredAnalysis

Make a clone of the flowset The implementor should know when they want a shallow or deep clone

Specified by:

cloneFlowSet in class StructuredAnalysis

processUnaryBinaryCondition

public DavaFlowSet processUnaryBinaryCondition(ASTUnaryBinaryCondition cond,
                                               DavaFlowSet input)

Description copied from class: StructuredAnalysis

To have maximum flexibility in analyzing conditions the analysis API breaks down the aggregated conditions to simple unary or binary conditions user defined code can then deal with each condition separately. To be able to deal with entire aggregated conditions the user should wite their own implementation of the method processCondition

Specified by:

processUnaryBinaryCondition in class StructuredAnalysis

processSynchronizedLocal

public DavaFlowSet processSynchronizedLocal(Local local,
                                            DavaFlowSet input)

Description copied from class: StructuredAnalysis

To deal with the local used for synch blocks

Specified by:

processSynchronizedLocal in class StructuredAnalysis

                                    DavaFlowSet input)

Description copied from class: StructuredAnalysis

Deal with the key in the switch construct

Specified by:

processSwitchKey in class StructuredAnalysis
