Instantiating an ada generic package
NettetCreating an array, and instantiating it with an aggregate mapping months to their actual durations in days. Iterating over the array, printing out the months, and the number of days for each. Being able to use enumeration values as indices is very helpful in creating mappings such as shown above one, and is an often used feature in Ada. Indexing Nettetof Ada that separated the instantiation of a generic package spec. from that of the corresponding body: the above would then appear of some form in which the package spec. instantiates only the generic spec: package A is . package C is new E (any actual params for the spec. only); type B is ; end; plus a body that instantiates the …

NettetIt may be useful to start interfacing Ada and C by using automatic binding generators. These can be done either by invoking gcc -fdump-ada-spec option (to generate an Ada binding to a C header file) or -gnatceg option (to generate a C binding to an Ada specification file). For example: gcc -c -fdump-ada-spec my_header.h gcc -c -gnatceg … NettetInstantiating the generic package: type Bookmark_Type is new Natural; -- records a location in the text document we are editing package Bookmark_Stacks is new Stacks (Max_Size => 20, Element_Type => Bookmark_Type); -- Allows the user to jump between recorded locations in a document Using an instance of a generic package:

NettetTo use a generic subprogram (or package), we have to create a real subprogram (or package) from the generic version. This process is called instantiating, and the result is called an instantiation or instance . These are big words for a simple concept. For example, here's how to create three Swap procedure instances from the generic one:
NettetThe Ada generic needs to be explicitly instantiated using a local name and the generic's parameters. Generic Packages Next, we're going to create a generic unit containing data and subprograms. In Java or C++, this is done through a class, while in Ada, it's a generic package.
