All Known Implementing Classes:

HsqldbSlaveAuthBean, JaasAuthBean, LdapAuthBean

AuthFunctionBeans are NOT directly usable as HyperSQL Authentication Function methods, they are POJO beans to be managed by AuthBeanMultiplexer (which does have a real HyperSQL Authentication Function static method).

Since:

2.0.1
