Constructor Detail

CFGMethodEntry

protected CFGMethodEntry()

Creates a new, empty object.

CFGMethodEntry

protected CFGMethodEntry(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

isMethodEntry

public boolean isMethodEntry()

Tests if this node indicates a method entry node.

Overrides:

isMethodEntry in class CFGNode

Returns:

always true.

addFormalIn

protected void addFormalIn(CFGParameter node)

Adds formal-in node.

Parameters:

node - A formal-in node of CFGs.

addFormalOut

protected void addFormalOut(CFGParameter node)

Adds formal-out node.

Parameters:

node - A formal-out node of CFGs.

getFormalIns

public java.util.ArrayList getFormalIns()

Returns formal-in nodes of the method starting from this method entry.

Returns:

The formal-in nodes.

getFormalOuts

public java.util.ArrayList getFormalOuts()

Returns formal-out nodes of the method starting from this method entry.

Returns:

The formal-in nodes.

getParameters

public java.util.ArrayList getParameters()

Returns parameter nodes of the method starting from this method entry.

Returns:

The parameter nodes, which is the same as the formal-in nodes.

getNumOfParameters

public int getNumOfParameters()

Returns the number of parameters.

Returns:

The number of parameter nodes.

hasParameter

public boolean hasParameter()

Tests if this method entry has a parameter.

Returns:

true if this method entry has a parameter, otherwise false.

getFormalIn

public CFGParameter getFormalIn(int index)

Returns a parameter node at the position in the formal-in list of this method entry.

Parameters:

index - The position where a parameter node is returned.

Returns:

The parameter node at the position, null if there is no parameter node found.

getFormalOut

public CFGParameter getFormalOut(int index)

Returns a parameter node at the position in the formal-out list of this method entry.

Parameters:

index - The position where a parameter node is returned.

Returns:

The parameter node at the position, null if there is no parameter node found.

print

public void print(java.lang.StringBuffer buf)

Collects information about this statement for printing.

Overrides:

print in class GraphNode

Parameters:

buf - The information about the stetement.
