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".
Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. [1] Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed.
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).
In a language supporting double dispatch, this is slightly more costly, because the compiler must generate code to calculate the method's offset in the method table at runtime, thereby increasing the overall instruction path length (by an amount that is likely to be no more than the total number of calls to the function, which may not be very ...
A linked list can be built by creating an array of these structures, and an integer variable to store the index of the first element. integer listHead Entry Records[1000] Links between elements are formed by placing the array index of the next (or previous) cell into the Next or Prev field within a given element. For example:
In a size-(n + 1) set, choose a distinguished element. Each subset either contains the distinguished element or does not. If a subset contains the distinguished element, then its remaining elements are chosen from among the other n elements. By the induction hypothesis, the number of ways to do that is 2 n. If a subset does not contain the ...
If a structure D embeds two structures B and C which both have a method F(), thus satisfying an interface A, the compiler will complain about an "ambiguous selector" if D.F() is called, or if an instance of D is assigned to a variable of type A. B and C's methods can be called explicitly with D.B.F() or D.C.F().
No code invokes public methods on this. Code that can be reused internally (by invocation from other methods of the same class) is encapsulated in a protected or private method; if it needs to be exposed directly to the users as well, then a wrapper public method calls the internal method. The previous recommendation can be relaxed for pure ...
