find()

Factory * xrpl::NodeStore::ManagerImp::find ( std::string const & name )

overridevirtual

Return a pointer to the matching factory if it exists.

Parameters

name	The name to match, performed case-insensitive.

Returns

nullptr if a match was not found.

Implements xrpl::NodeStore::Manager.

insert()

void xrpl::NodeStore::ManagerImp::insert ( Factory & factory )

overridevirtual

Add a factory.

erase()

void xrpl::NodeStore::ManagerImp::erase ( Factory & factory )

overridevirtual

Remove a factory.

makeBackend()

std::unique_ptr< Backend > xrpl::NodeStore::ManagerImp::makeBackend ( Section const & parameters, std::size_t burstSize, Scheduler & scheduler, beast::Journal journal )

overridevirtual

Create a backend.

Implements xrpl::NodeStore::Manager.

Definition at line 68 of file ManagerImp.cpp.

makeDatabase()

std::unique_ptr< Database > xrpl::NodeStore::ManagerImp::makeDatabase ( std::size_t burstSize, Scheduler & scheduler, int readThreads, Section const & backendParameters, beast::Journal journal )

overridevirtual

Construct a NodeStore database.

The parameters are key value pairs passed to the backend. The 'type' key must exist, it defines the choice of backend. Most backends also require a 'path' field.

Some choices for 'type' are: HyperLevelDB, LevelDBFactory, SQLite, MDB

If the fastBackendParameter is omitted or empty, no ephemeral database is used. If the scheduler parameter is omitted or unspecified, a synchronous scheduler is used which performs all tasks immediately on the caller's thread.

Note

If the database cannot be opened or created, an exception is thrown.

Parameters

name	A diagnostic label for the database.
burstSize	Backend burst size in bytes.
scheduler	The scheduler to use for performing asynchronous tasks.
readThreads	The number of async read threads to create
backendParameters	The parameter string for the persistent backend.
fastBackendParameters	[optional] The parameter string for the ephemeral backend.

Returns

The opened database.
