public void setNodeInformation(NodeInformation<T> ni)

Set the NodeInformation if and only if it was not previously set. Otherwise this function has no effect.

Parameters:

ni - the NodeInformation to set

setRoot

public void setRoot(T root)
             throws RuntimeException

Set the root if and only if it was not previously set. Otherwise this function has no effect. This function raises a RuntimeException is the NodeInformation was not previously set.

Parameters:

root - the root to set

Throws:

RuntimeException

isChildOf

public boolean isChildOf(String referenceIdentifier,
                         String requiredChild)

Checks if the node identified by the given reference identifier is a parent of the node identified by the required child identifier.

Parameters:

referenceIdentifier - the identifier of the reference node

requiredChild - the identifier of the node to check if it is a child of the reference node

Returns:

true if the reference node is a parent of the required child node, false otherwise

isParentOf
