isStart
public boolean isStart()
-
processNextStart
protected Traverser.Admin<E> processNextStart()

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, likePick
orMerge
. This traversal may be of local or global scope depending on the step implementation that works withoption()
.- Specified by:
addChildOption
in interfaceTraversalOptionParent<Pick,S,E>
- Overrides:
addChildOption
in classBranchStep<S,E,Pick>
-
reset
public void reset()
Description copied from interface:Step
Reset the state of the step such that it has no incoming starts. Internal states are to be reset, but any sideEffect data structures are not to be recreated.
