Abstract Value Members
- abstract def createTempFile(path: Path): FSDataOutputStream
Create a file with overwrite.
- abstract def renameTempFile(srcPath: Path, dstPath: Path, overwriteIfPossible: Boolean): Unit
Rename a file.
Rename a file.
- srcPath
Source path to rename
- dstPath
Destination path to rename to
- 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
FileAlreadyExistsExceptionin that case.
