Value Members

  1. def createAtomic(path: Path, overwriteIfPossible: Boolean): CancellableFSDataOutputStream

    Create a file and make its contents available atomically after the output stream is closed.

    Create a file and make its contents available atomically after the output stream is closed.

    path

    overwriteIfPossible

    If true, then the implementations must do a best-effort attempt to overwrite the file if it already exists. It should not throw any exception if the file exists. However, if false, then the implementation must not overwrite if the file already exists and must throw FileAlreadyExistsException in that case.
