Method Detail

doAnalysis

protected void doAnalysis()

Description copied from class: AbstractFlowAnalysis

Carries out the actual flow analysis. Typically called from a concrete FlowAnalysis's constructor.

Overrides:

doAnalysis in class ForwardFlowAnalysis

merge

protected void merge(Object in1,
                     Object in2,
                     Object 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

flowThrough

protected void flowThrough(Object inValue,
                           Object unit,
                           Object outValue)

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

Parameters:

inValue - the input flow

unit - the current node

outValue - the returned flow

copy

protected void copy(Object source,
                    Object dest)

Description copied from class: AbstractFlowAnalysis

Creates a copy of the source flow object in dest.

Specified by:

copy in class AbstractFlowAnalysis

entryInitialFlow

protected Object 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

newInitialFlow

protected Object 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

computeSynchNodes

public void computeSynchNodes()

getMonitor

public Map<String,FlowSet> getMonitor()

testMonitor

public void testMonitor()
