Obviously, some of the methods in table 12.4 are concerned with reading, others with writing; we’ll explain them separately. There are also methods that are specifically concerned with conversions. Their method names start with transform or new. We’ll illustrate their use in a separate section. Finally, we’ll cover the serialization support provided.

The eachDir, eachDirMatch, eachDirRecurse, and eachFile methods stand out as dealing with aspects of the filesystem rather than I/O operations. We’ll cover them first, followed by the traverse method, which provides the same functionality as the methods mentioned before, but provides a much more flexible way of handling files and directories. We’ll dive into the traverse method after handling the other four methods.
