AdapterDesignPatternTS

This EX is a Typescript EX that practices Adapter-design-pattern.

Adapter is a structural design pattern that allows objects with incompatible interfaces to collaborate.

In this Ex I implement the use of adapter design-pattern, using TypeScript.

Ex instructions

• Using interface, Create Processor interface that hsa a name and process method - gets input as string and returns string.
• Create StringProcessor as a base class for all string processors.
• StringProcessor implements Processor interface!
• Leave process method as abstract.
• Create UpCase (class, a kind of Processor), Which gets input as a string and returns the string in upper case
• Create DownCase (a kind of Processor), Which gets input as a string and returns the string in lower case
• Create SplitterMark (a kind of Processor), Which gets input as a string and returns the string with ! in between the words
• Create a Tester class with static method like so:
• process(p:Processor, s:string):void {
• log("Using Processor " + p.name)
• log(p.process(s))
• }
• Create a new class named String Swapper that has a method named swap, taking a string and returns a string.
• This method swaps each 2 characters, starting from both sides of the string, in that input ('Ahalan' -> 'nalahA')
• Assume you can't change existing code, How can we use our new string swapper class with our Tester process method?
• Create processors objects and test them via Tester.process
