In object-oriented programming, a composite is an object designed as a composition of one-or-more similar objects, all exhibiting similar functionality. This is known as a“has-a”relationship between objects. Below is the list of classes/objects used in the composite pattern, which has four :...

The Composite View pattern can be implemented using any number of strategies, but one of the more popular is the Custom Tag View Management Strategy. In fact, there are a number of custom tag libraries currently available for implementing composite views that separate view layout from view content...
