public java.io.InputStream openStream()
ByteSource
InputStream
for reading from this source. This method should return a new,
independent stream each time it is called.
The caller is responsible for ensuring that the returned stream is closed.

public java.io.InputStream openBufferedStream() throws java.io.IOException
ByteSource
InputStream
for reading from this source. The returned stream is
not required to be a BufferedInputStream
in order to allow implementations to simply
delegate to ByteSource.openStream()
when the stream returned by that method does not benefit
from additional buffering (for example, a ByteArrayInputStream
). This method should
return a new, independent stream each time it is called.
The caller is responsible for ensuring that the returned stream is closed.

to the end of the stream and return the total number of bytes that were read.
For some sources, such as a file, this method may use a more efficient implementation. Note that in such cases, it is possible that this method will return a different number of bytes than would be returned by reading all of the bytes (for example, some special files may return a size of 0 despite actually having content when read).
In either case, if this is a mutable source such as a file, the size it returns may not be the same number of bytes a subsequent read would return.
