Types

type Driver

type Driver struct {
	// contains filtered or unexported fields
}

Driver for apache age

func (Driver) DiscardQuery

func (d Driver) DiscardQuery(res dbms.QueryResult, seed *seed.Seed) bool

DiscardQuery returns true with probability 1/3 or if the query produced a non-nil error, else it returns false. Thereby causing queries to have an expected amount of 4 statements if they don't produce an error.

func (Driver) GetQueryResultType

func (d Driver) GetQueryResultType(res dbms.QueryResult, errorMessageRegex *dbms.ErrorMessageRegex) dbms.QueryResultType

GetQueryResultType evaluates the produced result and returns the type the result indicates.

func (Driver) GetSchema

func (d Driver) GetSchema(dbms.DBOptions) (*schema.Schema, error)

GetSchema returns the database's current schema

func (*Driver) Init

func (d *Driver) Init(opts dbms.DBOptions) error

Init the DB driver

func (Driver) IsEqualResult

func (d Driver) IsEqualResult(dbms.QueryResult, dbms.QueryResult) bool

IsEqualResult panics for apache age, as it hasn't been implemented yet

func (*Driver) Reset

func (d *Driver) Reset(opts dbms.DBOptions) error

Reset the database

func (Driver) RunQuery

func (d Driver) RunQuery(opts dbms.DBOptions, query string) dbms.QueryResult

RunQuery runs the query against the apache age DB and returns its result.

func (Driver) VerifyConnectivity

func (d Driver) VerifyConnectivity(dbms.DBOptions) (bool, error)

VerifyConnectivity checks whether the DB is still reachable and hasn't crashed.

type Implementation

type Implementation struct{}

Implementation for apache age

func (Implementation) GetDropIns

func (Implementation) GetDropIns() translator.DropIns

GetDropIns returns the clause drop-ins for the apache age implementation

func (Implementation) GetOpenCypherConfig

func (Implementation) GetOpenCypherConfig() config.Config

GetOpenCypherConfig returns the generation config for the apache age implementation
