Method Detail

flowThrough

protected void flowThrough(ConstantArrayAnalysis.ArrayState in,
                           Unit d,
                           ConstantArrayAnalysis.ArrayState 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,ConstantArrayAnalysis.ArrayState>

Parameters:

in - the input flow

d - the current node

out - the returned flow

newInitialFlow

protected ConstantArrayAnalysis.ArrayState 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,ConstantArrayAnalysis.ArrayState>

merge

protected void merge(ConstantArrayAnalysis.ArrayState in1,
                     ConstantArrayAnalysis.ArrayState in2,
                     ConstantArrayAnalysis.ArrayState 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,ConstantArrayAnalysis.ArrayState>

copy

protected void copy(ConstantArrayAnalysis.ArrayState source,
                    ConstantArrayAnalysis.ArrayState dest)

Description copied from class: AbstractFlowAnalysis

Creates a copy of the source flow object in dest.

Specified by:

copy in class AbstractFlowAnalysis<Unit,ConstantArrayAnalysis.ArrayState>

isConstantBefore

public boolean isConstantBefore(Stmt s,
                                Local arrayLocal)

getArrayTypesBefore

public ConstantArrayAnalysis.ArrayTypes getArrayTypesBefore(Stmt s,
                                                            Local arrayLocal)
