Class ReactiveStringBasedCassandraQuery

java.lang.Object

org.springframework.data.cassandra.repository.query.CassandraRepositoryQuerySupport

org.springframework.data.cassandra.repository.query.AbstractReactiveCassandraQuery

org.springframework.data.cassandra.repository.query.ReactiveStringBasedCassandraQuery

All Implemented Interfaces:

RepositoryQuery

public class ReactiveStringBasedCassandraQuery
extends AbstractReactiveCassandraQuery

String-based AbstractReactiveCassandraQuery implementation.

A ReactiveStringBasedCassandraQuery 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.

ReactiveStringBasedCassandraQuery

public ReactiveStringBasedCassandraQuery(ReactiveCassandraQueryMethod queryMethod,
                                         ReactiveCassandraOperations operations,
                                         SpelExpressionParser expressionParser,
                                         EvaluationContextProvider evaluationContextProvider)

Create a new ReactiveStringBasedCassandraQuery for the given CassandraQueryMethod, ReactiveCassandraOperations, SpelExpressionParser, and EvaluationContextProvider.

Parameters:

queryMethod - ReactiveCassandraQueryMethod on which this query is based.

operations - ReactiveCassandraOperations used to perform data access in Cassandra.

expressionParser - SpelExpressionParser used to parse expressions in the query.

evaluationContextProvider - EvaluationContextProvider used to access the potentially shared StandardEvaluationContext.
