Class QueuedDispatcherAssignmentStrategy

java.lang.Object
  com.googlecode.lightest.core.QueuedDispatcherAssignmentStrategy

All Implemented Interfaces:

IDispatcherAssignmentStrategy, groovy.lang.GroovyObject

Direct Known Subclasses:

SimpleDispatcherAssignmentStrategy

public abstract class QueuedDispatcherAssignmentStrategy
extends Object
implements groovy.lang.GroovyObject, IDispatcherAssignmentStrategy

Assigns testcases to dispatchers in a FIFO manner. Each testcase passed into assign() waits in a queue until getAvailableDispatchers() returns an idle ITaskDispatcher object the testcase can be assigned to.

Constructor Summary

QueuedDispatcherAssignmentStrategy()

Method Summary

boolean	assign(LightestTestCase testcase) Assigns a dispatcher to a testcase, and the testcase to the dispatcher.
protected List	getAvailableDispatchers(LightestTestCase testcase) Returns a potentially empty list of currently available (unassigned) task dispatchers for a given testcase.
protected abstract List	getCompatibleDispatchers(LightestTestCase testcase)
groovy.lang.MetaClass	getMetaClass()
Object	getProperty(String name)
Object	invokeMethod(String name, Object args)
void	setAssignmentTimeout(long timeout) Sets the maximum time a testcase will wait to have a task dispatcher assigned to it, before timing out.
void	setMetaClass(groovy.lang.MetaClass metaClass)
void	setProperty(String name, Object value)
void	unassign(LightestTestCase testcase) Breaks the bi-directional association between a dispatcher and a testcase.

public QueuedDispatcherAssignmentStrategy()

Method Detail

setAssignmentTimeout

public void setAssignmentTimeout(long timeout)

Sets the maximum time a testcase will wait to have a task dispatcher assigned to it, before timing out.

Parameters:

timeout - allotted time, in milliseconds. Non-positive values will be considered infinite time.

assign

public boolean assign(LightestTestCase testcase)

Assigns a dispatcher to a testcase, and the testcase to the dispatcher. Returns true if the assignment was successful, and false otherwise. Testcases that cannot be immediately assigned are queued up for assignment in FIFO order, and stay in the queue until assigned, or the timeout elapses (if any).

Specified by:

assign in interface IDispatcherAssignmentStrategy

Parameters:

testcase -

unassign

public void unassign(LightestTestCase testcase)

Description copied from interface: IDispatcherAssignmentStrategy

Breaks the bi-directional association between a dispatcher and a testcase.

Specified by:

unassign in interface IDispatcherAssignmentStrategy

getAvailableDispatchers

protected List getAvailableDispatchers(LightestTestCase testcase)

Returns a potentially empty list of currently available (unassigned) task dispatchers for a given testcase. This accommodates the possibility of filtering dispatchers based on testcase attributes, by starting with the result of getCompatibleDispatchers() passing in the testcase.

Parameters:

testcase - the testcase for which to return the dispatchers

getCompatibleDispatchers

protected abstract List getCompatibleDispatchers(LightestTestCase testcase)

getMetaClass

public groovy.lang.MetaClass getMetaClass()

Specified by:

invokeMethod

                           Object args)
