pageCount (Attribute)

The pageCount attribute reflects the total number of pages in the source database file.

pageCount get: The value of this attribute is the number of pages in the source database file as reported by SQLite. The database engine only updates this value during a step operation. If the source database is modified during a backup operation, then the value is not updated to account for the size of the source database file changing.
pageCount set: The programmer can not set thepageCountattribute. It is set internally by ooSQLite.
Remarks: ThepageCountand remaining (Attribute) attributes can be used to determine the progress of the backup. The percentage completion of the backup process may be calculated as:
Completion = 100&percent; * (buObj~pagecount - buObj~remaining) / buObj~pagecount
The database engine reports the page count and remaining values stored by the previous step operation, it does not actually inspect the source database file. This means that if the source database is written to by another thread or process after the call to step returns but before the values returned by the pageCountandremainingattributes are used, the values may be technically incorrect. This is not usually a problem. ThepageCountattribute must not be accessed after finish has been invoked. It calls into the database engine and the resources allowing that call have been released.
Details The functionality of thepageCountattribute is similar to that of the SQLite sqlite3_backup_pagecount API.
