Method Detail

createPreparedStatement

public reactor.core.publisher.Mono<com.datastax.oss.driver.api.core.cql.PreparedStatement> createPreparedStatement(ReactiveSession session)
                                                                                                            throws com.datastax.oss.driver.api.core.DriverException

Description copied from interface: ReactivePreparedStatementCreator

Create a statement in this session. Allows implementations to use PreparedStatements. The ReactiveCqlTemplate will attempt to cache the PreparedStatements for future use without the overhead of re-preparing on the entire cluster.

Specified by:

createPreparedStatement in interface ReactivePreparedStatementCreator

Parameters:

session - Session to use to create statement, must not be null.

Returns:

a prepared statement.

Throws:

com.datastax.oss.driver.api.core.DriverException - there is no need to catch DriverException that may be thrown in the implementation of this method. The ReactiveCqlTemplate class will handle them.

bindValues

public com.datastax.oss.driver.api.core.cql.BoundStatement bindValues(com.datastax.oss.driver.api.core.cql.PreparedStatement ps)
                                                               throws com.datastax.oss.driver.api.core.DriverException

Description copied from interface: PreparedStatementBinder

Bind parameter values on the given PreparedStatement.

Specified by:

bindValues in interface PreparedStatementBinder

Parameters:

ps - the PreparedStatement to invoke setter methods on.

Throws:

com.datastax.oss.driver.api.core.DriverException - if a DriverException is encountered (i.e. there is no need to catch DriverException)

getCql

public String getCql()

Description copied from interface: CqlProvider
