next

public void next(com.klg.jclass.higrid.RowNode rowNode)

Description copied from interface: Walkable

next() is invoked when the walk() routine moves to the next RowNode.

Specified by:

next in interface Walkable

Parameters:

rowNode - The rowNode that the walk() routine has traversed to.

previous

public void previous(com.klg.jclass.higrid.RowNode rowNode)

Description copied from interface: Walkable

previous() is invoked when the walk() routine moves to the previous RowNode.

Specified by:

previous in interface Walkable

Parameters:

rowNode - The rowNode that the walk() routine has traversed to.

find

public boolean find(com.klg.jclass.higrid.RowNode rowNode)

Description copied from interface: Walkable

find() is invoked by the walk() routine to test whether the passed rowNode meets the walk termination criteria.

Specified by:

find in interface Walkable

Parameters:

rowNode - The rowNode that the walk() routine has traversed to and is checking for termination.

getFoundNode
