Methods Documentation

DataType ReadLocked ( )

inline

Reads the persistent value.

Locked acces avoid concurrent access between application and persistence services.

Attention: This method is well designed to scalar variable access. Getting huge stucture with this method is not recommended : See persistent_read_lock.

void WriteLocked ( const DataType & value )

inline

Writes the persistent value.

Parameters

value The persistent value.

Locked acces avoid concurrent access between application and persistence services.

Attention: This method is well designed to scalar variable access. Getting huge stucture with this method is not recommended : See persistent_write_lock.

void WriteTo ( IDataStore & dataStore ) const

inlineprotectedvirtual

Writes to.

Parameters

dataStore [in,out] The dataStore.

DataType _Value_Unlocked

The persistent unlocked value.
