Package org.das2.util.filesystem Description

The fileSystem package introduces a filesystem abstraction that allows various types of file systems to be accessed in a convenient and uniform way. (A file system is a heirarchical set of files.) This allows clients to "mount" an ftp site and access the files easily and in the same way a local file system would be.

FileStorageModel is a class that models how filenames are constructed within a filesystem from times when files are used to implement a database.

FileSystem defines the interface clients see. Implementations of this include HTTPFileSystem, FTPFileSystem, and LocalFileSystem. FileObjects provide access to Files within the FileSystem, and metadata about the file.

HtmlUtil provides generally useful methods, such as scraping all the URL references from a stream. GlobUtil converts os globs like *.dat to regular expressions.
