FingerprintUserRecord Class Reference

Description

User record structure for use with fingerprint reader databases.

This structure contains a user ID (used as a database key) and an optional collection of associated data. A record of this type is stored for each enrolment into a fingerprint database.

Thread safety:

• Concurrent accesses to distinct objects: safe
• Concurrent accesses to same object: unsafe, unless all accesses are read-only (i.e. query functions)
