    • createPreparedStatement

      public ListenableFuture<com.datastax.oss.driver.api.core.cql.PreparedStatement> createPreparedStatement(com.datastax.oss.driver.api.core.CqlSession session) throws com.datastax.oss.driver.api.core.DriverException
      Description copied from interface: AsyncPreparedStatementCreator
      Create a statement in this session. Allows implementations to use PreparedStatements. The CqlTemplate will attempt to cache the PreparedStatements for future use without the overhead of re-preparing on the entire cluster.
      Specified by:
      createPreparedStatement in interface AsyncPreparedStatementCreator
      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 AsyncCqlTemplate class will handle them.

    • doPrepare

      protected CompletionStage<com.datastax.oss.driver.api.core.cql.PreparedStatement> doPrepare(com.datastax.oss.driver.api.core.CqlSession session)
      Invokes the statement preparation.
      Parameters:
      session -
      Returns:

    • 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
      Return the CQL string for this object, i.e. typically the CQL used for creating statements.
      Specified by:
      getCql in interface CqlProvider
      Returns:
      the CQL string.
