| getComparatorContext | | ComparatorContext getComparatorContext()(Code) | | Gets the comparator context for the value returned from this object grouper.
This comprator context will be used to find the ObjectComparator that will sort the
values return from
ObjectGrouper.getValue(Object) method whenever sorting is needed.
the converter context. |
| getConverterContext | | ConverterContext getConverterContext()(Code) | | Gets the converter context for the value returned from this object grouper.
