This can be executed to return SelectResults which can be either a ResultSet or a StructSet.
This class is intentionally not thread-safe. So multiple threads should not operate on the same Query object concurrently rather should have their own Query objects.
Public Member Functions | |
| virtual void | compile ()=0 |
| Compile the Query - client side query compilation is not supported. | |
| virtual SelectResultsPtr | execute (CacheableVectorPtr paramList, uint32_t timeout=DEFAULT_QUERY_RESPONSE_TIMEOUT)=0 |
| Executes the parameterized OQL Query on the cache server and returns the results. | |
| virtual SelectResultsPtr | execute (uint32_t timeout=DEFAULT_QUERY_RESPONSE_TIMEOUT)=0 |
| Executes the OQL Query on the cache server and returns the results. | |
| virtual const char * | getQueryString () const =0 |
| Get the query string provided when a new Query was created from a QueryService. | |
| virtual bool | isCompiled ()=0 |
| Check whether the Query is compiled - client side query compilation is not supported. | |
| void | preserveSB () const |
| Atomically increment reference count. | |
| int32_t | refCount () |
| |
| void | releaseSB () const |
| Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero. | |
| virtual void gemfire::Query::compile | ( | ) | [pure virtual] |
Compile the Query - client side query compilation is not supported.
| UnsupportedOperationException | because this is not currently supported. |
| virtual SelectResultsPtr gemfire::Query::execute | ( | CacheableVectorPtr | paramList, | |
| uint32_t | timeout = DEFAULT_QUERY_RESPONSE_TIMEOUT | |||
| ) | [pure virtual] |
Executes the parameterized OQL Query on the cache server and returns the results.
| paramList | The query parameters list | |
| timeout | The time (in seconds) to wait for query response, optional. This should be less than or equal to 2^31/1000 i.e. 2147483. |
| IllegalArgumentException | if timeout parameter is greater than 2^31/1000. | |
| QueryException | if some query error occurred at the server. | |
| IllegalStateException | if some error occurred. | |
| NotConnectedException | if no java cache server is available. For pools configured with locators, if no locators are available, the cause of NotConnectedException is set to NoAvailableLocatorsException. returns A smart pointer to the SelectResults which can either be a ResultSet or a StructSet. |
