In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state and behavior that are each either associated with a particular object or with all objects of that class.
In computer science, a container is a class or a data structure [1] [2] whose instances are collections of other objects. In other words, they store objects in an organized way that follows specific access rules. The size of the container depends on the number of objects (elements) it contains.
The class name appears an underlined concatenation of the instance name (if any), a colon (':'), and the actual class name. [1] Instance members are scoped to a specific instance. Attribute values may vary between instances; Method invocation may affect the instance's state (i.e. change instance's attributes)
The action is an object whose responsibility is to describe what has taken place: for example, an action describing one user "following" another might contain a user id, a target user id, and the type USER_FOLLOWED_ANOTHER_USER. [44]
In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field.. In computing, an attribute is a specification that defines a property of an object, element, or file.
The composite pattern describes a group of objects that are treated the same way as a single instance of the same type of object. The intent of a composite is to "compose" objects into tree structures to represent part-whole hierarchies. Implementing the composite pattern lets clients treat individual objects and compositions uniformly. [1]
