SolverInOwnThread

public SolverInOwnThread()

Method Detail

createThread

protected abstract java.lang.Thread createThread()

Create the thread to use. If this returns null, the solve methods operates synchronously, i.e., it immediately solves the partial task.

Returns:

thread to use for operation, or null in synchronous case

dispose

public void dispose()

Description copied from class: Solver

This method is invoked by the Task when this solver is removed from the task. Subclasses have to implement this method in order to free resources (e.g., created threads).

Specified by:

dispose in class Solver

run

public void run()

Specified by:

run in interface java.lang.Runnable

solve

protected void solve()

Description copied from class: Solver

This method has to be implemented by subclasses in order to solve the current partial task synchronously or asynchronously. After the partial task has been solved, the method Task.partialTaskDone(Solver) has to be invoked.

Specified by:

solve in class Solver

solveImpl

protected abstract void solveImpl(PartialTask task)

This method has to be implemented to perform the actual work.

Parameters:

task - task to solve
