java.lang.Objectjava.io.OutputStream
com.google.common.io.FileBackedOutputStream
@Beta public final class FileBackedOutputStream
An OutputStream that starts buffering to a byte array, but
switches to file buffering once the data reaches a configurable size.
This class is thread-safe.
| Constructor Summary | |
|---|---|
FileBackedOutputStream(int fileThreshold)
Creates a new instance that uses the given file threshold, and does not reset the data when the InputSupplier returned by
getSupplier() is finalized. |
|
FileBackedOutputStream(int fileThreshold,
boolean resetOnFinalize)
Creates a new instance that uses the given file threshold, and optionally resets the data when the InputSupplier returned
by getSupplier() is finalized. |

public FileBackedOutputStream(int fileThreshold)
InputSupplier returned by
getSupplier() is finalized.
fileThreshold - the number of bytes before the stream should
switch to buffering to a file
public FileBackedOutputStream(int fileThreshold,
boolean resetOnFinalize)
InputSupplier returned
by getSupplier() is finalized.
fileThreshold - the number of bytes before the stream should
switch to buffering to a fileresetOnFinalize - if true, the reset() method will
be called when the InputSupplier returned by getSupplier() is finalized| Method Detail |

public InputSupplier<InputStream> getSupplier()
public void reset()
throws IOException
close() if not already closed, and then resets this
object back to its initial state, for reuse. If data was buffered
to a file, it will be deleted.
IOException - if an I/O error occurred while deleting the file buffer
