Method Detail

addChildOption

public void addChildOption(Pick pickToken,
                           Traversal.Admin<S,E> traversalOption)

Description copied from interface: TraversalOptionParent

The child as defined by the token it takes, like Pick or Merge. This traversal may be of local or global scope depending on the step implementation that works with option().

Specified by:

addChildOption in interface TraversalOptionParent<Pick,S,E>

Overrides:

addChildOption in class BranchStep<S,E,Pick>

toString

public String toString()
