)

[static]

NewL()

Definition at line 29 of file CDatabase.cpp.

void CDatabase::CreateDatabaseL

(

)

Creates database in the store and create a table and add columns to it.

Definition at line 79 of file CDatabase.cpp.

void CDatabase::ReadfromDatabaseL

(

)

This function is called by the ReaderThread in SemaphoreExample. It creates a console to display the data read from the database and starts a periodic function to read the database at an interval of 1 second.

Definition at line 220 of file CDatabase.cpp.

void CDatabase::WritetoDatabaseL

(

)

This function is called by the WriteThread in the SemaphoreExample and it starts a periodic function to write data in the database at an interval of 1 sec.

Definition at line 135 of file CDatabase.cpp.

TInt CDatabase::PeriodicReadL

(

TAny *

aPtr

)

[static]

The call back function associated with the CPeriodic object of the CDatabase class and is called by the ReadfromDatabaseL() function.

Definition at line 237 of file CDatabase.cpp.

void CDatabase::PeriodicReadFuncL

(

)

This function is called periodically at an interval of 1 second, it opens the database , reads one row and displays the numbers to the console.

Definition at line 248 of file CDatabase.cpp.

TInt CDatabase::PeriodicWriteL

(

TAny *

aPtr

)

[static]

The call back function associated with the CPeriodic object of the CDatabase class and is called by the WritetoDatabaseL() function.

Definition at line 145 of file CDatabase.cpp.

void CDatabase::PeriodicWriteFuncL

(

)

This function is called periodically at an interval of 1 sec, it opens the database, inserts one row and fills it with integer values.

Definition at line 157 of file CDatabase.cpp.

void CDatabase::ConstructL

(

)

[protected]

Constructs a CPeriodic object, a database , opens the global semaphore.
