is not associated with aFile
.- Specified by:
getFile
in interfaceByteProvider
- Returns:
- the underlying file for this byte provider
-
getName
Description copied from interface:ByteProvider
Returns the name of theByteProvider
. For example, the underlying file name.- Specified by:
getName
in interfaceByteProvider
- Returns:
- the name of the
ByteProvider
or null if there is no name
-
getAbsolutePath
Description copied from interface:ByteProvider

. For example, the complete path to the file.- Specified by:
getAbsolutePath
in interfaceByteProvider
- Returns:
- the absolute path to the
ByteProvider
or null if not associated with aFile
.
-
length
public long length()Description copied from interface:ByteProvider

may have occupied- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceByteProvider
- Specified by:
close
in interfaceCloseable
