Decorator (Design Pattern)

This structural pattern increases the functionality of a class. Looks similar to a proxy, but it gets the object injected

Unsigned integer Range: [0,255] Binary: 00000000 =++=> 00000001 =++=> … =++=> 11111111 Hex: 0x00 =++=> 0x01 =++=> … =++=> 0xFF

Phishing comes in mind if you want access to another account, but you aren’t able to bypass the login (e.g.

Fundamentals A Virus is a program which attaches itself to other programs. A Worm is a program which tries to

The Proxy and the VPN-Server are both a node in the communication between the client and the server. Both ways

This behavioral pattern is used to let objects behave differently based on their current state.

This structural pattern controls the access to a class. Looks similar to a decorator, but it instantiates the object by

This structural pattern translates one class interface into another. This is a class adapter, but there also exists an object

This creational pattern assures that just one object can get instantiated of that class.
