At the core of this package are the Source/Sink types:
ByteSource
,
CharSource
,
ByteSink
and
CharSink
. They are factories for I/O streams that
provide many convenience methods that handle both opening and closing streams for you.
This package is a part of the open-source Guava libraries. For more information on Sources and Sinks as well as other features of this package, see I/O Explained on the Guava wiki.
