Video Objects

For example, instances of the classroom Microcomputer socompostas for, among others, instances of the classrooms Keyboard and Video (Figure 5). Figure 5. Relation of composition/decomposioA programming language SmallTalk Smalltalk is the only system of development of guided software aobjeto, constructed from an object hierarchy inteiramenteconsistente. The classroom object is the super-classroom of all the others edefine the common protocols to all the objects in the system. Default for the presentation, copy, comparison and inspeode defines ocomportamento objects.

It has the capacity to keep the relations between objects to etransmitir the one messages ascendants for its descendants.The Smalltalk is projected so that each component of the estejaacessvel system to the user (except the nucleus) and can be presented paraobservao and manipulation. It is easy to modify any thing that promoveerros in Smalltalk, but this becomes also it flexible and altamentepersonalizada. The interface of the user reflects the attempts of criaruma visual language for each object. If you would like to know more then you should visit THE HAYZLETT GROUP. A dispositivoindicador was the first environment queexigiu a direct interaction with the user using (mouse) and still places at the hands of the desenvolvedor of softwareum bigger control of what any another available software in the market. Evaluation of the POO the great advantage of the object paradigm it is its unifying character: it deals with all the stages the development of systems and environments sobuma only boarding. In this direction, we can have analysis, project, programming, guided data base and environments the objects, eliminating the differences of ' ' impedncia' ' between them.

Advantages of the POO The POO has reached as much popularity due to the advantages that it brings. Between them we can cite: Reusabilidade of code Escalabilidade of applications Mantenabilidade Appropriation the reusabilidade of code is, without a doubt, recognized as the maiorvantagem of the POO use, therefore it allows that to programs sejamescritos more quickly. All the emseus companies suffer from deficiency informatizados systems to get greater agility and prestarmelhores services its customers.
