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