HistHookExpression

Description:

The HistHookExpression function is called whenever the batch evaluates the transition expression during batch execution. When this function is called, it adds an entry in the TransitionExpression table of the BatchHistory database. This can be called multiple times per expression because an expression can have unlimited length.
