	Scheduler pattern - Wikipedia, the free encyclopedia
		It provides a mechanism to implement a scheduling policy, but is independent of any specific scheduling policy — the policy is encapsulated in its own class and is reusable.
		The read/write lock pattern is usually implemented using the scheduler pattern to ensure fairness in scheduling.
		The scheduler pattern is not quite the same as the scheduled-task pattern.

	Design Pattern Synopses
		The Filter pattern is a special case of the Decorator pattern, where a data source or data sink object is wrapped to add logic to the handling of a data stream.
		The Composite pattern also allows the objects in the tree to be manipulated in a consistent manner, by requiring all of the objects in the tree to have a common superclass or interface.
		The Flyweight pattern is often combined with the Composite pattern to represent the leaf nodes of a hierarchical structure with shared objects.

	EuroPLoP 2002: Papers
		The patterns help to balance the forces that the overall complexity must be limited, that the code must be modifyable and extensible, the source code must be clear and the overall system must be robust.
		Patterns are written up in short form and linked to each other in a hypertext way with the ultimate goal of making them a pattern language.
		Scheduling is done according to the activities’ priorities and scheduling policies having to guarantee the execution of the most critical activities first and some fairness criteria, too.

	Design Pattern Synopses from Patterns in Java, Volume 1 Second Edition
		The Decorator pattern extends the functionality of an object in a way that is transparent to its clients, by implementing the same interface as the original class and delegating operations to the original class.
		The Guarded Suspension pattern is used in the implementation of the Double Buffering pattern to coordinate the actions of data-requesting threads with the read-ahead thread.
		The two phase termination pattern may be used in the implementation of the Double Buffering pattern to shut down the read-ahead thread in an orderly way.

	scheduler.8
		Any connections to this port are processed synchronously in the scheduler at points in the execution where the state is internally consistent.
		The patterns for the clauses are matched, in sequence, with the channel/host string for each recipient address.
		The pattern introducing a clause must start in the first column of a line, and the variable assignments or keywords inside a clause must not start in the first column of a line.

		This pattern proposes a solution for some design decisions that have to be taken in order to implement the State pattern, such as the creation and the control of State objects and the execution of state transitions.
		The patterns address specific aspects of team behaviour, including the formation of an accurate recognition of a team's capacity, bootstrapping a new team, focussing on the problem space, being aware of the team's work rate, making sure that deliverables are used, learning to make appropriate assignments to individuals, and handling personnel changes.
		Patterns presented in this paper are part of our current work in this area, we hope that developers of geographical applications could use it but also document their own experience in this powerful way.

	Enterprise Software Pattern Synopses
		The Heartbeat pattern may be used with the Two Phase Commit pattern to ensure that the Coordinator object is able to detect catastrophic failures of component transactions in a bounded amount of time.
		One of the applications of the Object Replication pattern is to ensure that an object is near its accessors.
		The Virtual Proxy pattern, described in Volume 1, may be used by an implementation of the Persistence Layer pattern to defer the fetching of objects that are part of a more complex object but may not be needed for some uses of the complex object.

	TecNote 3010 - Converting TS1 to TS2 Databases
		The default Pattern Table under controller screen MM->2->4 should be modified as follows so that the pattern number (Pat#) and the default split number is the same for patterns 1 through 24.
		Pattern 48 is reserved for free operation as explained later in this TecNote.
		If you use pattern 254 (defined by NTCIP for free operation), the controller uses sequence 1 (defined in MM->1->2->4) which may or may not be the sequence you desire for free operation.

	Transparent Distributed Operating ...
		The scheduler is just a model, whereby a virtual machine can accept objects and schedule their execution, with the critical understanding that the multitasking is cooperative.
		Sending a scheduler from one machine to another is a 'mind-bender', and not worth going into at this time, however if you try this approach, you will no doubt experience the eureka moment; and stunning new capability will become apparent.
		What this is trying for is to establish a 'pattern' by which the functionality of multiple distributed operating systems can be coordinated into a virtual operating system, in a simple and intuitive fashion.

	Command pattern
		In computer programming, command pattern is one of design patterns that use a value object[?] to communicate the details of the action that is desired.
		When: There is a proliferation of similar methods, and the interface to implement that kind of object is becoming unwieldy.
		This is an example of using Perl to shoehorn a Command Object pattern onto a non Command Object interface.

	ePro Scheduler - Scheduling
		For most operations, the weekly schedule changes constantly due to employee vacation or illness or having to work past the end of their shift.
		Employee certifications with expiration dates are used by the scheduling software to prevent scheduling of employees lacking the proper credentials.

	Command Pattern (Site not responding. Last check: 2007-10-12)
		I used the command pattern in a Scheduler utility.
		In my first use of the Scheduler, all scheduled events did the same thing, and I made the handler do all the task work.
		In a later application I used the Scheduler to schedule a variety of tasks.

	Charming Python: Implementing "weightless threads" with Python generators
		The difference is that the scheduler itself should decide branch targets rather than receive them from the generator/coroutines.
		The way the scheduler is set up here causes the whole scheduler to stop when one thread does so.
		Rather than simply give high-priority threads an integer number of time-slices, the scheduler could measure the time actually spent in each weightless thread, and dynamically adjust the thread scheduling to be more "fair" to under-serviced threads (fairness being perhaps related to thread priority).

	Smooth Program Scheduler - Automate Windows Programs - XemiComputers
		If you have one of those recorders on your computer then you will be able to make unattended recordings using Scheduler.
		In other words you get the opportunity to create a scheduled task that will launch the audio program, start recording from selected sound source, stop the recording at some point later in time and finally exit the program.
		Scheduler's main window shows the list of all scheduled tasks.

	Active Object \| paulbridger.net
		Whereas in the Monitor Object pattern interface methods could block, Active Object interface methods return after queueing the relevant processing in an internal "Activation List".
		The full Active Object pattern can be quite complex since we need some way of returning method return values, as well as a way to bind method calls to their parameters for deferred execution.
		Implementations will vary, but conceptually the interface methods will immediately return an object called a "Future", through which the method result may be obtained when the queued processing is completed.

		One advantage over other solutions: with the Scheduler pattern, you can start B2B tasks systematically in a well-organized fashion, as well as decouple one task from another.
		As for application security, the client, which starts the scheduler, should first obtain authorization, implemented through either declarative or programmatic authorization.
