Constructor Detail

Node

protected Node(Node prev,
               XmlObject object)

Constructs node.

Parameters:

prev - previous node in linked list

object - assessment object (test, test part, section, item reference, precondition or branch rule)

Method Detail

isBorder

public boolean isBorder()

Returns true if this node is border node; false otherwise.

Border node is node on border. It is either start or end node, and it is not middle node.

Returns:

true if this node is border node; false otherwise

isStart

public boolean isStart()

Returns true if this node is start node; false otherwise.

Start node is node on beginning of test, test part, section or item reference.

Returns:

true if this node is start node; false otherwise

isEnd

public boolean isEnd()

Returns true if this node is end node; false otherwise.

End node is node on end of test, test part, section or item reference.

Returns:

true is this node is end node; false otherwise

isMiddle

public boolean isMiddle()

Returns true if this node is middle node; false otherwise.

Middle node is node which is between start and end node. There can be more middle nodes between one start and end node.

Returns:

true is this node is middle node; false otherwise

isItemRef

public boolean isItemRef()

Returns true if this node is item reference node; false otherwise.

Item reference node is middle node with item reference object.

Returns:

true if this node is item reference node; false otherwise

isJump

public boolean isJump()

Returns true if this node is jump node; false otherwise.

Jump node is middle node with precondition or branch rule object.

Returns:

true if this node is jump node; false otherwise

isPreCondition

public boolean isPreCondition()

Returns true if this node is precondition node; false otherwise.

Precondition node is jump node with precondition object.

Returns:

true is this node is precondition node; false otherwise

isBranchRule

public boolean isBranchRule()

Returns true if this node is branch rule node; false otherwise.

Branch rule node is jump node with branch rule object.

Returns:

true is this node is branch rule node; false otherwise

getIndex

public int getIndex()

Gets index (position in linked list) of this node.

Index of first node in linked list is 0.

Returns:

index (position in linked list) of this node

getPrev

public Node getPrev()

Gets previous node in linked list (can be null).

Returns:

previous node in linked list (can be null)

getNext

public Node getNext()

Gets next node in linked list (can be null).

Returns:

next node in linked list (can be null)

getObject

public XmlObject getObject()

Gets assessment object (test, test part, section, item reference, precondition or branch rule) of this node.

Returns:

assessment object (test, test part, section, item reference, precondition or branch rule) of this node

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
