Combining structural subtyping and external dispatch

Donna Malayeri
2007 Companion to the 22nd ACM SIGPLAN conference on Object oriented programming systems and applications companion - OOPSLA '07  
Nominal subtyping allows programmers to explicitly express design intent, and, when types are associated with run time tags, enables run-time "type" tests (e.g., downcasts) and external/multimethod dispatch  ...  As many have observed (for instance, [6, 7, 18] ), in the absence of external dispatch, one must resort to unwieldy doubledispatch code (such as the "Visitor" design pattern [13] ), which, aside from  ...  Finally, and most importantly, nominal subtyping is necessary for run-time subtyping tests (such as downcasts) as well as external and multimethod dispatch.  ...

Adaptive Event Dispatching in Serverless Computing Infrastructures [article]

Manuel Stein
2019 arXiv   pre-print
The term "serverless" has become a synonym for the entirely resource-transparent deployment model of cloud-based event-driven distributed applications.  ...  This work investigates how adaptive event dispatching can improve serverless platform resource efficiency and contributes a novel approach that allows for better scaling and fitting of the platform's resource  ...  The Serverless Scheduling Problem Lopes and Menascé [30] simply distinguish from centralised and decentralised, but many patterns exist to organise schedulers, such as peer-to-peer distributed hash tables  ...

Re-dispatch and Application of FACTs for Transactions Allocation in Deregulated Electricity Markets

Archana Jaisingpure, V. K. Chandrakar, R. M. Mohril
2021 WSEAS Transactions on power systems  
The result indicates that the combination of TCSC and SVC incredibly discount the measure of re-dispatched power which provides optimal operating point nearer to the market settlement.  ...  The transmission lines are uncongested using re-dispatch method and then taxes are calculated for the establishment of the flexible A.C. transmission systems (FACTS) devices in the transmission network  ...  We could connect FACTS either in series or in shunt with the power system or indeed in an associated pattern to give compensation for the power system.  ...

A Cloud Based Mobile Dispatching System with Built-in Social CRM Component: Design and Implementation

Cosmina Ivan, Razvan Popa
2015 Computers  
The second reason has to do with the advantages that this method has over traditional dispatching systems, such as being able to see the vehicle approaching on a map, being able to rate a driver and the  ...  The first reason is a more mobile-centric usage pattern, where users relate to apps for fulfilling different needs that they have.  ...  The argument can be any value, as long as the type of the argument matches the type of the target. All interactions matching a filter form a stream.  ...

2007 Software, Practice & Experience  
This enables the definition of policies that select different methods at different times for the same combination of argument classes.  ...  The function should return the index in the array of methods corresponding to the best match for the given classes. If no suitable method is found, bestMatch returns −1. handleMissing().  ...  Dispatching over instructions The software architecture of Ovm has evolved over time. Originally, the instruction objects used dedicated methods to perform bytecode manipulation.  ...
