Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
Cascading can be implemented in terms of chaining by having the methods return the target object (receiver, this, self).However, this requires that the method be implemented this way already – or the original object be wrapped in another object that does this – and that the method not return some other, potentially useful value (or nothing if that would be more appropriate, as in setters).
If the objects of a display are not sufficiently widely spaced, the objects are difficult to identify and select with attention due to spatial crowding, which can prevent tracking. [4] [11] High object speeds have a similar effect—faster objects are harder to track, and humans are completely unable to track objects that move sufficiently fast ...
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate. It requires selecting and identifying relevant aspects of a situation in the real world and then developing ...
In computing, a Research Object is a method for the identification, aggregation and exchange of scholarly information on the Web.The primary goal of the research object approach is to provide a mechanism to associate related resources about a scientific investigation so that they can be shared using a single identifier.
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on ...
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
In computing, chaining is a technique used in computer architecture in which scalar and vector registers generate interim results which can be used immediately, without additional memory references which reduce computational speed. [1] The chaining technique was first used by Seymour Cray in the 80 MHz Cray 1 supercomputer in 1976. [2]
