Method Detail

select

public Node select(Node node,
                   Direction dir,
                   TraversalContext context)

Description copied from interface: Algorithm

Traverse from owner, in direction dir. Return a the new target Node or null if no suitable target is found. Typically, the implementation of override algorithm handles only parent's direct children and looks like this: 1) Find the nearest parent of the "owner" that is handled by this algorithm (i.e. it's a direct child of the root). 2) select the next node within this direct child using the context.selectInSubtree() and return it 2a) if no such node exists, move to the next direct child in the direction (this is where the different order of direct children is defined) or if direct children are not traversable, the select the first node in the next direct child

select in interface Algorithm

selectFirst

public Node selectFirst(TraversalContext context)

Description copied from interface: Algorithm

Return the first traversable node for the specified context (root).

Specified by:

selectFirst in interface Algorithm

Parameters:

context - the context that contains the root

Returns:

the first node

selectLast

public Node selectLast(TraversalContext context)

Description copied from interface: Algorithm

Return the last traversable node for the specified context (root).

Specified by:

selectLast in interface Algorithm

Parameters:

context - the context that contains the root

Returns:

the last node
