CursorTravelMode::NONBLOCKINGThe implementation will throw a + CursorWouldBlockException, if the data for the new + position are not retrieved yet.

The following pseudo-code illustrates the usage of a non-blocking + cursor: + + @code{.java} + bProcessedAllRows = false + while ( !bProcessedAllRows ) + { + cursor.setPropertyValue( "CursorTravelMode", BLOCKING ) + + cursor.travelSomeWhere() + collectRowData() + + cursor.setPropertyValue( "CursorTravelMode", NONBLOCKING ) + + bGoOn = true; + while ( bGoOn ) + { + try + { + cursor.travelSomeWhere() + collectRowData() + } + catch ( CursorWouldBlockException ) + { + // No more data at the moment. + bGoOn = false + } + } + + doSomethingWithCollectedRowData() + + bProcessedAllRows = ... + } + @endcode + +

+ If this property is not supported, the implementation needs to provide + a blocking cursor. +

+ +

+ The implementation initially needs to set the value of this property + to CursorTravelMode::BLOCKING. +
