In most modern OO languages chaining methods together is common, and IMHO elegant, practice. In jquery, for example, you often see code like:
$('div').addClass('container').css('color', 'white').length
Does writing your objects to allow this have a name?

The chain-of-responsibility pattern is structurally nearly identical to the decorator pattern, the difference being that for the decorator, all classes handle the request, while for the chain of responsibility, exactly one of the classes in the chain handles the request.
Method chaining, also known as named parameter idiom, is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
Chain of responsibility pattern is used to achieve loose coupling in software design where a request from client is passed to a chain of objects to process them.
Chain of Responsibility is a behavioral design pattern that lets you pass requests along a chain of handlers. Upon receiving a request, each handler decides either to process the request or to pass it to the next handler in the chain.
Method Chaining is the core concept behind building a Fluent Interface
