Examples of org.apache.commons.vfs.FileContent

org.apache.commons.vfs.FileContent
Represents the data content of a file.

To read from a file, use the InputStream returned by {@link #getInputStream}.

To write to a file, use the OutputStream returned by {@link #getOutputStream} method. This will create the file, and the parentfolder, if necessary.

A file may have multiple InputStreams open at the sametime.
