Method cascading (original) (raw)
In object-oriented programming, method cascading is syntax which allows multiple methods to be called on the same object. This is particularly applied in fluent interfaces. For example, in Dart, the cascade: a..b ..c; is equivalent to the individual calls: a.b;a.c; Method cascading is much less common than method chaining – it is found only in a handful of object-oriented languages, while chaining is very common. A form of cascading can be implemented using chaining, but this restricts the interface; see , below.
