The most vexing parse is a counterintuitive form of syntactic ambiguity resolution in the C++ programming language. In certain situations, the C++ grammar cannot distinguish between the creation of an object parameter and specification of a function's type. In those situations, the compiler is required to interpret the line as a function type ...
In computer programming, initialization or initialisation is the assignment of an initial value for a data object or variable. The manner in which initialization is performed depends on the programming language , as well as the type, storage class, etc., of an object to be initialized.
The definition of aggregates was changed to explicitly exclude any class with member initializers; therefore, they are not allowed to use aggregate initialization. C++14 relaxes this restriction, [3] allowing aggregate initialization on such types. If the braced init list does not provide a value for that argument, the member initializer takes ...
Finally, the constructor body is executed. This ensures proper order of initialization, i.e. the fields of a base class finish initialization before initialization of the fields of an object class begins. There are two main potential traps in Java's object initialization. First, variable initializers are expressions that can contain method calls.
If the helper object is static (one per class loader), an alternative is the initialization-on-demand holder idiom [11] (See Listing 16.6 [12] from the previously cited text.) // Correct lazy initialization in Java class Foo { private static class HelperHolder { public static final Helper helper = new Helper (); } public static Helper getHelper ...
Creation procedures can be explicitly invoked to re-initialize existing objects. Every effective (i.e., concrete or non-abstract) class must designate at least one creation procedure. Creation procedures must leave the newly initialized object in a state that satisfies the class invariant. [b]
Oracle America agreed to settle a class-action lawsuit in May for $115 million over allegations that the company was tracking user activity online and offline, according to a complaint filed in a ...
The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .
