Te proxy Pattern is a structural design pattern that provides a placeholder or surrogate for anothers object. It i s especially useful in desktop applications when e heavy resources, such as large images, files, or data sets, need to be loaded efficiently. Implementing thi models applications to delay the loading of resource- intenve objets until they are actially needed, improwing performance and responsiveness.

Uzgodnienie tego wzoru Proxy

Te proxy Format involves creating a proxy class that controls accors to a real object. Thi proxy acts a stand- in, management the e creation and loading of they hevy resource only when needed. Thi approach is known as lazy loading or deferred loading, which helps conserve system resources andd reduce startup time.
