Detailed Description

Class representing a database backend.

Member Function Documentation

createBackendFromEngine()

std::shared_ptr< api::DatabaseBackend > ledger::core::api::DatabaseBackend::createBackendFromEngine ( const std::shared_ptr< DatabaseEngine > &  engine )

static

Create a database backend instance from the given DatabaseEngine implementation.

enableQueryLogging()

virtual std::shared_ptr<DatabaseBackend> ledger::core::api::DatabaseBackend::enableQueryLogging ( bool  enable )

pure virtual

Enable or disable query logging. By default logging is disabled. Query logging will record every SQL query in log streams.

Returns

this database backend (to chain configuration calls)

Implemented in ledger::core::DatabaseBackend.

getConnectionPoolSize()

virtual int32_t ledger::core::api::DatabaseBackend::getConnectionPoolSize ( )

pure virtual

Get the maximum number of concurrent connection that the backend is able to open on a single database.

Returns

the size of the connection pool.

Implemented in ledger::core::ProxyBackend, and ledger::core::SQLite3Backend.

getSqlite3Backend()

std::shared_ptr< api::DatabaseBackend > ledger::core::api::DatabaseBackend::getSqlite3Backend ( )

static

Create an instance of SQLite3 database.

Returns

DatabaseBackend object

isLoggingEnabled()

virtual bool ledger::core::api::DatabaseBackend::isLoggingEnabled ( )

pure virtual

Return true if query logging is enabled.

Returns

trye if query logging is enabled, false otherwise.

Implemented in ledger::core::DatabaseBackend.
