Class StringBasedCassandraQuery

java.lang.Object

org.springframework.data.cassandra.repository.query.AbstractCassandraQuery

org.springframework.data.cassandra.repository.query.StringBasedCassandraQuery

All Implemented Interfaces:

RepositoryQuery

public class StringBasedCassandraQuery
extends AbstractCassandraQuery

String-based AbstractCassandraQuery implementation.

A StringBasedCassandraQuery expects a query method to be annotated with Query with a CQL query. String-based queries support named, index-based and expression parameters that are resolved during query execution.
