org.springframework.data.hazelcast.repository.support.HazelcastQueryLookupStrategy

All Implemented Interfaces:

org.springframework.data.repository.query.QueryLookupStrategy

public class HazelcastQueryLookupStrategy
extends Object
implements org.springframework.data.repository.query.QueryLookupStrategy

Ensures HazelcastPartTreeQuery is used for query preparation rather than KeyValuePartTreeQuery or other alternatives.

Constructor Detail

HazelcastQueryLookupStrategy

public HazelcastQueryLookupStrategy(org.springframework.data.repository.query.QueryLookupStrategy.Key key,
                                    org.springframework.data.repository.query.QueryMethodEvaluationContextProvider evaluationContextProvider,
                                    org.springframework.data.keyvalue.core.KeyValueOperations keyValueOperations,
                                    Class<? extends org.springframework.data.repository.query.parser.AbstractQueryCreator<?,?>> queryCreator,
                                    com.hazelcast.core.HazelcastInstance hazelcastInstance)

Required constructor, capturing arguments for use in resolveQuery(java.lang.reflect.Method, org.springframework.data.repository.core.RepositoryMetadata, org.springframework.data.projection.ProjectionFactory, org.springframework.data.repository.core.NamedQueries).

Assertions copied from KayValueRepositoryFactory.KeyValueQUeryLookupStrategy which this class essentially duplicates.

Parameters:

key - Not used

evaluationContextProvider - For evaluation of query expressions

keyValueOperations - Bean to use for Key/Value operations on Hazelcast repos

queryCreator - Likely to be HazelcastQueryCreator

hazelcastInstance - Instance of Hazelcast
