Detailed Description
Extends WODisplayGroup- provide access to the filtered objects
- allows you to add qualifiers to the final query qualifier (as opposed to just min/equals/max with the keys)
- clears out the sort ordering when the datasource changes. This is a cure fix to prevent errors when using switch components.
Constructor & Destructor Documentation
| ERXDisplayGroup | ( | ) |
| ERXDisplayGroup | ( | EOKeyValueUnarchiver | unarchiver | ) | [private] |
Creates a new ERXBatchingDisplayGroup from an unarchiver.
- Parameters:
-
unarchiver the unarchiver to construct this display group with
Member Function Documentation
| NSArray<T> allObjects | ( | ) |

| void clearExtraQualifiers | ( | ) |
| static Object decodeWithKeyValueUnarchiver | ( | EOKeyValueUnarchiver | unarchiver | ) | [static] |
Decodes an ERXDisplayGroup from the given unarchiver.
- Parameters:
-
unarchiver the unarchiver to construct this display group with
- Returns:
- the corresponding batching display group
| NSArray<T> displayedObjects | ( | ) |
Overridden to return generic types
| Object displayNextBatch | ( | ) |
Overriden to re-set the selection. Why is this cleared in the super class?
| Object displayPreviousBatch | ( | ) |
Overriden to re-set the selection. Why is this cleared in the super class?
| Object fetch | ( | ) |
Overridden to localize the fetch specification if needed.
| NSArray<T> filteredObjects | ( | ) |
Returns all objects, filtered by the qualifier().
| int indexOfFirstDisplayedObject | ( | ) |
Overridden to return correct result when no objects are displayed
| int indexOfLastDisplayedObject | ( | ) |
Overridden to return correct index if the number of filtered objects is not a multiple of numberOfObjectsPerBatch and we are on the last batch index. The superclass incorrectly uses allObjects instead of displayedObjects to determine the index value.
| EOQualifier qualifierFromQueryValues | ( | ) |
Overridden to support extra qualifiers.
| T selectedObject | ( | ) |
Overridden to return generic types
| NSArray<T> selectedObjects | ( | ) |
Overridden to track selection changes.
| Object selectFilteredObjects | ( | ) |
Selects the visible objects.
| void setDataSource | ( | EODataSource | eodatasource | ) |
Overridden to clear out the sort ordering if it is no longer applicable.
| void setNumberOfObjectsPerBatch | ( | int | i | ) |
Overriden to re-set the selection. Why is this cleared in the super class?
| void setQualifierForKey | ( | EOQualifier | qualifier, | |
| String | key | |||
| ) |
| void setSelectedObjects | ( | NSArray | nsarray | ) |
Overridden to track selection changes.
| boolean setSelectionIndexes | ( | NSArray | nsarray | ) |
Overridden to track selection changes.
| void setSortOrderings | ( | NSArray | nsarray | ) |
Overridden to log a message when more than one sort order exists. Useful to track down errors.
| NSArray<T> sortedObjects | ( | ) |
Returns allObjects(), first filtered by the qualifier(), then sorted by the sortOrderings().
| NSArray<EOSortOrdering> sortOrderings | ( | ) |
Overridden to return generic types
