Member predicate Make::Container::getExtension
Gets the extension of this container, that is, the suffix of its base name after the last dot character, if any.
In particular,
- if the name does not include a dot, there is no extension, so this predicate has no result;
- if the name ends in a dot, the extension is the empty string;
- if the name contains multiple dots, the extension follows the last dot.
Here are some examples of absolute paths and the corresponding extensions (surrounded with quotes to avoid ambiguity):
| Absolute path | Extension |
|---|---|
| "/tmp/tst.txt" | "txt" |
| "/tmp/.classpath" | "classpath" |
| "/bin/bash" | not defined |
| "/tmp/tst2." | "" |
| "/tmp/x.tar.gz" | "gz" |
