The Lazy Initialization pattern delays the creation of an expensive object until its first use. This improves performance, especially if the object is not always needed. In Dart, this is commonly achieved using the lazySet or similar techniques within a class. The example below demonstrates this with a potentially …

The Lazy Initialization pattern delays the creation of an object until its first use. This can improve performance if the object is expensive to create and not always needed. In Scala, this is naturally achieved using the lazy keyword. The lazy keyword ensures that the variable is only initialized once, when its value …

The Lazy Initialization pattern delays the creation of an expensive object until its first use. This improves performance by avoiding unnecessary object creation if the object’s methods are never called. The provided PHP code implements this using a private static property to hold the instance and a public static …

The Lazy Initialization pattern delays the creation of an object until it’s actually needed, improving performance if the object is rarely used. This avoids unnecessary resource consumption during program startup. Our Ruby implementation uses a simple instance variable and a conditional assignment within a getter …

The Lazy Initialization pattern delays the initialization of a property until it is first accessed. This improves performance, particularly when initialization is expensive, as it avoids unnecessary computation if the property remains unused. In Swift, this is achieved using the lazy keyword. The property is declared …

The Lazy Initialization pattern delays the creation of an object until it’s actually needed. This improves performance when object creation is expensive and the object isn’t always used. Kotlin provides built-in support for lazy initialization using the lazy delegate. The code defines a ReportGenerator …

The Lazy Initialization pattern ensures that the creation of a resource-intensive object is deferred until it’s actually needed (accessed) for the first time. Subsequent accesses then return the already created instance. This avoids unnecessary initialization overhead, improving performance especially if the …

The Lazy Initialization pattern delays the initialization of an object until it’s actually needed. This can improve performance, especially if the initialization process is resource-intensive, as it avoids unnecessary work. This example uses a sync.Once to ensure the initialization happens only once, even in …

The Lazy Initialization pattern delays the creation of an expensive object until it’s actually needed. This improves performance if the object is not always used. The implementation uses a pointer initialized to NULL. The first time the object is requested, the pointer is checked for NULL. If it is, the object is …

The Lazy Initialization pattern delays the creation of an expensive object until its first use. This improves performance by avoiding unnecessary initialization overhead, especially when the object might not even be needed during runtime. The code demonstrates this by creating a class with a computationally intensive …
