other arguments passed to methods

Value

  • dbCreate returns TRUE upon success and FALSE in the event of an error. dbInit returns an object inheriting from class "filehash"

Details

dbCreate creates the necessary files or directory for the database. If those files already exist nothing is done.

dbInit takes a database name and returns an object inheriting from class "filehash".

The type argument specifies the format in which the database should be stored on the disk. If not specified, the default type will be used (as specified by filehashOption).
