Guidelines: Compilation
Dependency in Implementation
Topics
Explanation
An important use of a dependency relationship is to represent compilation dependencies.
A compilation dependency exists from one element to the elements that are needed
to compile it. In C++, for example, the compilation dependencies are indicated
with #include statements. In Ada, compilation dependencies are indicated by
the with clause. In Java the compilation dependency is indicated by the import
statement. In general there should be no cyclical compilation dependencies.
Example 1:
The following component diagram illustrates compilation dependencies
between source files. The Invoicing_UI file (the top), requires Invoice, which
requires Order to compile.
