findUnique(String, Object...).
As oppose, to the query(String) method, this method allows for more generic queries (against multiple regions even) to be executed.
Note that the local query service is used if the region is configured as a client without any pool configuration or server connectivity - otherwise the query service on the default pool
is being used.E - type parameter specifying the type of the select results.query - the OQL query statement to execute.params - an array of Object values used as arguments to bind to the OQL query parameters (such as $1).SelectResults instance holding the objects matching the queryInvalidDataAccessApiUsageException - in case the query returns a single result (not a SelectResults).QueryService.newQuery(String),

Query.execute(Object[])<E> com.gemstone.gemfire.cache.query.SelectResults<E> query(String query)
Region.query(String) method. Filters the values of this region using the predicate given as a string with the syntax of the WHERE clause of the query language.
The predefined variable this may be used inside the predicate to denote the current element being filtered.
This method evaluates the passed in where clause and returns results. It is supported on servers as well as clients.
When executed on a client, this method always runs on the server and returns results.
When invoking this method from the client, applications can pass in a where clause or a complete query.E - type parameter specifying the type of the select results.query - an OQL Query language boolean query predicate.Region.query(String)<T> T execute(GemfireCallback<T> action) throws DataAccessException

T - type parameter specifying the returned result type.action - callback object that specifies the Gemfire action to execute.exposeNativeRegion - whether to expose the native GemFire region to callback code.null.DataAccessException - in case of GemFire errors.
