Constructor Detail

BranchingPath

public BranchingPath()

Creates a new empth BranchingPath.

BranchingPath

public BranchingPath(WizardStep step)

Creates a new BranchingPath that is initialized with the specified step.

Parameters:

step - the first step of the path.

Method Detail

getNextPath

protected Path getNextPath(MultiPathModel model)

Gets the path to traverse after this path has exhausted all its steps. This method will call iterate over each path selector to determine the path to return.

Specified by:

getNextPath in class AbstractPath

Returns:

the next path in the sequence.

Throws:

java.lang.IllegalStateException - if no matching path is found.

addBranch

public void addBranch(Path path,
                      Condition condition)

Adds a possible branch from this path.

Parameters:

path - the AbstractPath to traverse based when the condition returns true.

condition - a Condition that activates this path.

acceptVisitor

public void acceptVisitor(PathVisitor visitor)

Specified by:

acceptVisitor in interface Path

Specified by:
