Constructor Detail

AbstractN1qlBasedQuery

protected AbstractN1qlBasedQuery(CouchbaseQueryMethod queryMethod,
                                 CouchbaseOperations couchbaseOperations)

Method Detail

getCount

protected abstract com.couchbase.client.java.query.Statement getCount(ParameterAccessor accessor,
                                                                      Object[] runtimeParameters)

The statement for a count() query. This must aggregate using count with the alias CountFragment.COUNT_ALIAS.

Returns:

true if the count statement should also be used when the return type of the QueryMethod is a primitive type.
