Member Function Documentation

GetInitialQueryCursor() [1/2]

template<typename K , typename V >

QueryCursor<K, V> ignite::cache::query::continuous::ContinuousQueryHandle< K, V >::GetInitialQueryCursor ( )

inline

Gets the cursor for initial query.

Can be called only once, throws IgniteError on consequent calls.

Returns

Initial query cursor.

GetInitialQueryCursor() [2/2]

template<typename K , typename V >

QueryCursor<K, V> ignite::cache::query::continuous::ContinuousQueryHandle< K, V >::GetInitialQueryCursor ( IgniteError &  err )

inline

Gets the cursor for initial query.

Can be called only once, results in error on consequent calls.

Parameters

err

Error.

Returns

Initial query cursor.

IsValid()

template<typename K , typename V >

bool ignite::cache::query::continuous::ContinuousQueryHandle< K, V >::IsValid ( ) const

inline

Check if the instance is valid.

Invalid instance can be returned if some of the previous operations have resulted in a failure. For example invalid instance can be returned by not-throwing version of method in case of error. Invalid instances also often can be created using default constructor.

Returns

True if the instance is valid and can be used.
