25/// CodeInjector is an interface which is responsible for injecting AST
26/// of function definitions that may not be available in the original source.
27///
28/// The getBody function will be called each time the static analyzer examines a
29/// function call that has no definition available in the current translation
30/// unit. If the returned statement is not a null pointer, it is assumed to be
31/// the body of a function which will be used for the analysis. The source of
32/// the body can be arbitrary, but it is advised to use memoization to avoid
33/// unnecessary reparsing of the external source that provides the body of the
34/// functions.
