Class StreamBuffer

java.lang.Object

java.io.OutputStream

io.inversion.utils.StreamBuffer

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class StreamBuffer
extends OutputStream

Uses an in memory buffer to hold output until bufferSize data is written then will switch over to writing everything to a temp file. You get the data back by calling getInputStream() which can be called multiple times, each time returning a new InputStream with all the data. Calling getInputStream() will close the OutputStream and prevent additional writing.
