Event OpenFileForWriting

The OpenFileForWriting event is a signal to the FileAdapter to open the file specified in order to write events to it.

A FileHandle event will be sent back if the file has been opened successfully. It will be in response to the requestId specified here, and will contain the sessionId used for the file.

Subsequent file line events generated from this file and sent to the correlator will reference this ID.

For Fixed Width files, the optional members fieldLength, isLeftAligned and pad character must be specified. These will be mapped to the payload when being sent to the adapter. Subsequent Write line events are responsible for ensuring that the data contained within them is capable of being written in accordance to the widths supplied.
