Constructor Detail

PCRelation

public PCRelation()

the default constructor

PCRelation

public PCRelation(String parentName,
                  String childName,
                  boolean deleted)

                  String childName)

the overloaded constructor

Method Detail

getParent

public String getParent()

Returns the parent in the edge.

Returns:

parent

getChild

public String getChild()

Returns the child in the edge.

Returns:

child

setAbstractParentID

public void setAbstractParentID(String id)

Sets the abstract parent id associated with the edge.

Parameters:

id - the abstract id

setAbstractChildID

public void setAbstractChildID(String id)

Sets the abstract child id associated with the edge.

Parameters:

id - the abstract id

getAbstractParentID

public String getAbstractParentID()

Returns the abstract parent id associated with the edge.

Returns:

parent

getAbstractChildID

public String getAbstractChildID()

Returns the abstract child id associated with the edge.

Returns:

child

clone

public Object clone()

returns a new copy of the Object

Overrides:

clone in class Object

equals

public boolean equals(Object o)

Checks if an object is similar to the one referred to by this class. We compare the primary key to determine if it is the same or not.

Overrides:

equals in class Object

Returns:

true if the primary key (parent,child) match. else false.

compareTo

public int compareTo(Object o)

toString

public String toString()

Returns the textual description.

Specified by:

toString in class Data

Returns:

textual description.

toDOT

public String toDOT()
             throws IOException

Returns the DOT description of the object. This is used for visualizing the workflow.

Returns:

String containing the Partition object in XML.

Throws:

IOException - if something fishy happens to the stream.

toDOT

public void toDOT(Writer stream,
                  String indent)
           throws IOException

Returns the DOT description of the object. This is used for visualizing the workflow.

Parameters:

stream - is a stream opened and ready for writing. This can also be a StringWriter for efficient output.

indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal.

Throws:

IOException - if something fishy happens to the stream.

setChild

public void setChild(String childNode)

Sets the child of the edge.

Parameters:

childNode - the child node

setParent

public void setParent(String parentNode)

Sets the parent of the edge.

Parameters:

parentNode - the parent node
