Constructor Detail

SolutionSet

public SolutionSet(String schemaName,
                   Set<? extends ZValue> solutions)

Creates a SolutionSet from a Set containing all of the solutions.

Parameters:

schemaName - The name of the schema that created this solution set.

solutions - The set of solutions to go into this SolutionSet.

SolutionSet

public SolutionSet(String schemaName,
                   ZBinding solution)

Creates a SolutionSet containing just one solution.

Parameters:

schemaName - The name of the schema that created this solution set.

solution - The solution to go into this singleton SolutionSet.

Method Detail

getSchemaName

public String getSchemaName()

Getter function for the name of the schema that created this solution set.

Returns:

The name of the schema.

getCurrentSolution

public ZBinding getCurrentSolution()

Getter function for the currently selected solution in the SolutionSet.

Returns:

The solution (or null if there is no current solution).

hasCurrentSolution

public boolean hasCurrentSolution()

Returns:

true if there is a current solution (i.e. if getCurrentSolution() will not return null).

hasNextSolution

public boolean hasNextSolution()

Returns:

true if there is a next solution in the SolutionSet (similar to hasNext in Iterators).

nextSolution

public void nextSolution()

Steps the current solution to the next in this SolutionSet. Does nothing if it is already at the first solution.

hasPreviousSolution

public boolean hasPreviousSolution()

Returns:

true if there is a previous solution in the SolutionSet (similar to hasPrevious in Iterators).

previousSolution

public void previousSolution()

Steps the current solution to the previous in this SolutionSet. Does nothing if it is already at the last solution.

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Registers a PropertyChangeListener. The only property that will trigger a PropertyChangeEvent is currentSolution.

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Unregisters a PropertyChangeListener. The only property that will trigger a PropertyChangeEvent is currentSolution.

getPropertyChangeListeners

public PropertyChangeListener[] getPropertyChangeListeners()

Returns all of the PropertyChangeListeners. The only property that will trigger a PropertyChangeEvent is currentSolution.

addPropertyChangeListener

public void addPropertyChangeListener(String propertyName,
                                      PropertyChangeListener listener)

Registers a PropertyChangeListener for a specific property. The only property that will trigger a PropertyChangeEvent is currentSolution.

removePropertyChangeListener

public void removePropertyChangeListener(String propertyName,
                                         PropertyChangeListener listener)

Unregisters a PropertyChangeListener for a specific property. The only property that will trigger a PropertyChangeEvent is currentSolution.

getPropertyChangeListeners

public PropertyChangeListener[] getPropertyChangeListeners(String propertyName)

Returns all of the PropertyChangeListeners for a specific property. The only property that will trigger a PropertyChangeEvent is currentSolution.

getPositionLabel

public String getPositionLabel()

Returns:

true if there are no PropertyChangeListeners registered. public boolean hasListeners(String propertyName) { return propertyChangeSupport_.hasListeners(propertyName); }; /**
