MultiRunStatementsFinder

public MultiRunStatementsFinder(UnitGraph g,
                                SootMethod sm,
                                Set<SootMethod> multiCalledMethods,

Method Detail

merge

protected void merge(BitSet in1,
                     BitSet in2,
                     BitSet out)

Description copied from class: AbstractFlowAnalysis

Compute the merge of the in1 and in2 sets, putting the result into out. The behavior of this function depends on the implementation ( it may be necessary to check whether in1 and in2 are equal or aliased ). Used by the doAnalysis method.

Specified by:

merge in class AbstractFlowAnalysis<Unit,BitSet>

flowThrough

protected void flowThrough(BitSet in,
                           Unit unit,
                           BitSet out)

Description copied from class: FlowAnalysis

Given the merge of the out sets, compute the in set for s (or in to out, depending on direction). This function often causes confusion, because the same interface is used for both forward and backward flow analyses. The first parameter is always the argument to the flow function (i.e. it is the "in" set in a forward analysis and the "out" set in a backward analysis), and the third parameter is always the result of the flow function (i.e. it is the "out" set in a forward analysis and the "in" set in a backward analysis).

Specified by:

flowThrough in class FlowAnalysis<Unit,BitSet>

Parameters:

in - the input flow

unit - the current node

out - the returned flow

copy

protected void copy(BitSet source,
                    BitSet dest)

Description copied from class: AbstractFlowAnalysis

Creates a copy of the source flow object in dest.

Specified by:

copy in class AbstractFlowAnalysis<Unit,BitSet>

entryInitialFlow

protected BitSet entryInitialFlow()

Description copied from class: AbstractFlowAnalysis

Returns the initial flow value for entry/exit graph nodes. This is equal to AbstractFlowAnalysis.newInitialFlow()

Overrides:

entryInitialFlow in class AbstractFlowAnalysis<Unit,BitSet>

newInitialFlow

protected BitSet newInitialFlow()

Description copied from class: AbstractFlowAnalysis

Returns the flow object corresponding to the initial values for each graph node.

Specified by:

newInitialFlow in class AbstractFlowAnalysis<Unit,BitSet>

getMultiRunStatements

public FlowSet getMultiRunStatements()

indexOf

protected int indexOf(Object o)
