Commands
UNICOM® Digital Transformation Toolkit (UDTT™) commands provide a generalized navigation framework to maximize the reusage of businesses and transactions.
Command interface is the central interface for all entity classes
All entity classes in the toolkit will implement command interface, this means you can reuse your entity everywhere.
Everything inside the component is generalized
In this toolkit, all interface are generalized as following:
Command <ContextType, ReturnType, Exception Type>
All the execute method is defined as follows:
ReturnType execute(ContextType context) throws ExceptionType
Rich Level of the executable units
As the following figure shows, UDTT Commands have three levels and will be enriched at future version.
