Interface LayoutController

All Known Implementing Classes:

LayoutControllerImpl

public interface LayoutController

A LayoutController is the one responsible for controlling the states of the LayoutModel. It always controls the current workspace model.

This controller is a singleton and can therefore be found in Lookup:

LayoutController lc = Lookup.getDefault().lookup(LayoutController.class);

Method Detail

getModel

LayoutModel getModel()

Returns the model of the currently selected Workspace.

setLayout

Sets the Layout to execute.

Parameters:

layout - the layout that is to be selected

executeLayout

void executeLayout()

Executes the current Layout.

executeLayout

void executeLayout(int numIterations)

Executes the current layout for numIterations iterations.

Parameters:

numIterations - the number of iterations of the algorithm

canExecute

boolean canExecute()

Determine if the current Layout can be executed.

Returns:

true if the layout is executable.

stopLayout

void stopLayout()

Stop the Layout's execution.

canStop

boolean canStop()
