94 results about "Return type" patented technology

In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method. In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function.

Method for packaging UOML into application program interface

The invention discloses a method for enclosing UOML into API which comprises the following procedures that: the UOML object is mapped into a composite data type of the programming language, the property of the UOML object corresponds to the variables of simple data type or the variables of complex data type in the composite data type, sub-elements of the UOML object correspond to the variables of simple data type or the variables of complex data type in the composite data type; the UOML operation is mapped into an API function prototype of the programming language, the object of the UOML operation corresponds to the parameters of the API function prototype; the operation corresponding to the API function in an API function body of the programming language is converted into the UOML operation according to the defined mappings in the procedures, and the return result of the operation is converted into a return type of the programming language. The API functions of the UOML aiming at different programming languages are realized by the method, thereby, the application developers of different programming languages can directly realize the application on the document library system by calling the corresponding API function, and the developing efficiency is improved.
