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).
Cascading can be implemented using method chaining by having the method return the current object itself. Cascading is a key technique in fluent interfaces , and since chaining is widely implemented in object-oriented languages while cascading isn't, this form of "cascading-by-chaining by returning this " is often referred to simply as "chaining".
A small set of fields is defined and can be extended with additional text values if required. This method is deprecated in PDF 2.0. In PDF 1.4, support was added for Metadata Streams, using the Extensible Metadata Platform (XMP) to add XML standards-based extensible metadata as used in other file formats. PDF 2.0 allows metadata to be attached ...
The term "fluent interface" was coined in late 2005, though this overall style of interface dates to the invention of method cascading in Smalltalk in the 1970s, and numerous examples in the 1980s. A common example is the iostream library in C++ , which uses the << or >> operators for the message passing, sending multiple data to the same ...
Cascading is a particular case of ensemble learning based on the concatenation of several classifiers, using all information collected from the output from a given classifier as additional information for the next classifier in the cascade. Unlike voting or stacking ensembles, which are multiexpert systems, cascading is a multistage one.
Moreover, HDBSCAN can self-adjust by using a range of distances instead of a specified one. Lastly, the method OPTICS creates a reachability plot based on the distance from neighboring features to separate noise from clusters of varying density. These methods still require the user to provide the cluster center and cannot be considered automatic.
The method cascade syntax was adopted from Smalltalk. [76] This syntax provides a shortcut for invoking several methods one after another on the same object. Dart's mixins were influenced by Strongtalk [citation needed] [77] [78] and Ruby. Dart makes use of isolates as a concurrency and security unit when structuring applications. [79]
