loadFile
in class DefaultFileFormat
fileName
- File-name (stream-name) to read from (can be null
).detail
- Further implementation-specific information ("r" or "rw" for mapped mode).
true

. This metod is optional.
The stream should be opened before - only the reOpen(false,null)
call
can be used.

first).support
- Implementation-specific data (e.g. second BitStream

file-formats with DataFileFormat.DOUBLE_STREAM
property).
true
if the operation was successful.
