mgr - the non-null statement manager

bridge - the non-null statement bridge

Throws:

NullPointerException - if query is null

SimpleStatementImpl

public SimpleStatementImpl(com.datastax.driver.core.RegularStatement statement,
                           StatementManagerImpl mgr,
                           StatementBridge bridge)
