CqlTemplate (Spring CQL 1.5.22.RELEASE API)

java.lang.Object
- org.springframework.cassandra.support.CassandraAccessor
- - org.springframework.cassandra.core.CqlTemplate

All Implemented Interfaces:

InitializingBean, CqlOperations
```
public class CqlTemplate
extends CassandraAccessor
implements CqlOperations
```
This is the central class in the Cassandra core package. CqlTemplate simplifies the use of Cassandra and helps to avoid common errors. The template executes the core Cassandra workflow, leaving application code to provide CQL and result handling. The template executes CQL queries, provides different ways to extract and map results, and provides Exception translation to the generic, more informative exception hierarchy defined in the org.springframework.dao package.
For working with POJOs, use the CassandraTemplate.

                                       Runnable listener)
```
    Description copied from interface: CqlOperations
    
    Executes the provided CQL Query with the provided Runnable, which is started after the query has completed.
    A more useful method than this one is CqlOperations.queryAsynchronously(String, AsynchronousQueryListener), where you're given the ResultSetFuture after the query has been executed.
    
    Specified by:
    
    queryAsynchronously in interface CqlOperations
    
    Parameters:
    
    cql - The Query

    Description copied from interface: CqlOperations
