Examples of org.eclipse.jgit.util.TemporaryBuffer$LocalFile

org.eclipse.jgit.util.TemporaryBuffer
A fully buffered output stream using local disk storage for large data.
Initially this output stream buffers to memory and is therefore similar to ByteArrayOutputStream, but it shifts to using an on disk temporary file if the output gets too large.
The content of this buffered stream may be sent to another OutputStream only after this stream has been properly closed by {@link #close()}.
