Writee

Semantics

The role type Writee corresponds to the requirement that the associated player in a FileIO connection be the next block of data that gets written to the end of a sequential file. The format of this block is specified in the RecordFormat property associated with the SeqFile component. The player type WriteNext in UniCon captures the semantics of this data block. The responsibility of the WriteNext player is to act as the next data block that gets written to a sequential file in a FileIO connection.

In a FileIO connection whose IOMode is either WriteOnly or ReadWrite, there must be exactly one data block that gets written next to the sequential file (i.e., one Writee
role/player association).
