Constructor Detail

CFGCall

protected CFGCall()

Creates a new, emoty object.

CFGCall

protected CFGCall(int sort,
                  org.w3c.dom.Element elem)

Creates a new node.

Parameters:

sort - The sort of this node.

elem - A DOM element corresponding to this node.

Method Detail

setName

protected void setName(java.lang.String name)

Sets the name of a called method.

Parameters:

name - The name of the called method.

getName

public java.lang.String getName()

Returns the name of a called method.

Returns:

The name of the called method.

getReturnVariable

public JxVariable getReturnVariable()

Returns a variable wrapper storing the return value.

Returns:

The variable wrapper, or null if this method call returns no value.

setFqnOfCalledMethod

protected void setFqnOfCalledMethod(java.lang.String fqn)

Sets the fully-qualified name of the type of the return value.

Parameters:

fqn - The fully-qualified name of the type of the return value.

getFqnOfCalledMethod

public java.lang.String getFqnOfCalledMethod()

Returns the fully-qualified name of the type of the return value.

Returns:

The fully-qualified name of the type of the return value.

addActualIn

protected void addActualIn(CFGParameter node)

Adds actual-in node.

Parameters:

node - A actual-in node of CFGs.

addActualOut

protected void addActualOut(CFGParameter node)

Adds actual-out node.

Parameters:

node - A actual-out node of CFGs.

getActualIns

public java.util.ArrayList getActualIns()

Returns actual-in nodes of this method call.

Returns:

The actual-in nodes.

getActualOuts

public java.util.ArrayList getActualOuts()

Returns actual-out nodes of this method call.

Returns:

The actual-out nodes.

getArguments

public java.util.ArrayList getArguments()

Returns argument nodes of this method call.

Returns:

The argument nodes, which is the same as the actual-in nodes.

getNumOfArguments

public int getNumOfArguments()

Returns the number of arguments.

Returns:
