org.hyperledger.fabric.contract.Context

public class Context
extends Object

This context is available to all 'transaction functions' and provides the transaction context. It also provides access to the APIs for the world state using getStub()

Applications can implement their own versions if they wish to add functionality. All subclasses MUST implement a constructor, for example

 public MyContext extends Context {

     public MyContext(ChaincodeStub stub) {
        super(stub);
     }
 }
