Method Detail

update

public void update()

preorder

public boolean preorder(int node)

Description copied from interface: DepthFirst.Visitor

Method called when the node is initially reached.

Specified by:

preorder in interface DepthFirst.Visitor

Parameters:

node - the reached node.

Returns:

true if the subtree should be traversed, false if it should be pruned from the traversal. In the latter case, the two other methods are not called for the node.

postorder

public void postorder(int node)

Description copied from interface: DepthFirst.Visitor

Method called when all the children of the node have been traversed.

Specified by:

postorder in interface DepthFirst.Visitor

Parameters:

node - the reached node.

isValueUndefined

public boolean isValueUndefined(int row)

Description copied from class: ColumnProxy

Returns true if the ith value is undefined.

Specified by:

isValueUndefined in interface Column

Specified by:

isValueUndefined in interface RowComparator

Overrides:

isValueUndefined in class ColumnProxy

Parameters:

row - the index

Returns:

true if the ith value is undefined.

getIndex

public int getIndex(int row)

getValueAt

public String getValueAt(int row)

Description copied from class: ColumnProxy

Returns the String representation of the element at the specified position in this column or null if the element is undefined. The representation is generated by the current format.

Specified by:

getValueAt in interface Column

Overrides:

getValueAt in class ColumnProxy

Parameters:

row - index of element representation to return.

Returns:

the String representation of element at the specified position in this column or null if the element is undefined.

compare

public int compare(int a,
                   int b)

Description copied from class: ColumnProxy

Specified by:

compare in interface IntComparator

Overrides:

compare in class ColumnProxy
