Constructor Details

InterPDGDD

public InterPDGDD(PDGNode src,
 PDGNode dst,
 JVariableReference jv)

Creates a new object that represents an edge with respect to data flow.

Parameters:

src - the source node of this edge

dst - the destination node of this edge

jv - the variable related to this data dependence

InterPDGDD

public InterPDGDD(PDGNode src,
 PDGNode dst)

Creates a new object that represents an edge with respect to data flow.

Parameters:

src - the source node of this edge

dst - the destination node of this edge

Method Details

getVariable

public JVariableReference getVariable()

Returns the variable related to this data dependence. The value of a variable defined in the source node reaches that used in the destination node.

Returns:

the variable storing the passed value

setParameterIn

public void setParameterIn()

Sets as a parameter-in dependence.

Overrides:

setParameterIn in class InterPDGEdge

setParameterOut

public void setParameterOut()

Sets as a parameter-out dependence.

Overrides:

setParameterOut in class InterPDGEdge

setFieldAccess

public void setFieldAccess()

Sets as a field access dependence.

Overrides:

setFieldAccess in class InterPDGEdge

setUncoveredFieldAccess

public void setUncoveredFieldAccess()

Sets as an uncovered field access dependence.

Overrides:

setUncoveredFieldAccess in class InterPDGEdge

setSummary

public void setSummary()

Sets as a summary data dependence.

Overrides:

setSummary in class InterPDGEdge

toString

public String toString()

Overrides:

toString in class InterPDGEdge
