With lazy initialization, the object is first set to null. Whenever the object is requested, the object is checked, and if it is null, the object is then immediately created and returned. For example, lazy loading for a widget can be implemented in the C# programming language as such:
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed. It is a kind of lazy evaluation that refers specifically to the instantiation of objects or other resources.
In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only when an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs).
In software engineering, the initialization-on-demand holder (design pattern) idiom is a lazy-loaded singleton. In all versions of Java, the idiom enables a safe, highly concurrent lazy initialization of static fields with good performance. [1] [2]
A singleton implementation may use lazy initialization in which the instance is created when the static method is first invoked. In multithreaded programs, this can cause race conditions that result in the creation of multiple instances. The following Java 5+ example [6] is a thread-safe implementation, using lazy initialization with double ...
For example, if your budget is $75 for weekly groceries, make a shopping list with $60 worth of items you need. Add $15 on the end for an unknown item. "That way, you give yourself permission to ...
Over the past couple months the term "lazy girl jobs" has gone viral. Like so many new catchphrases this day and age, it began on TikTok as a hashtag, coined by Gabrielle Judge, a 26-year-old...
Hibernate can be configured to lazy load associated collections. [2]: 289–293 Lazy loading is the default as of Hibernate 3. Related objects can be configured to cascade operations from one object to the other. For example, a parent Album class object can be configured to cascade its save and delete operations to its child Track class objects.
