ERD2WQueryPage Class Reference
Inherits er::directtoweb::pages::ERD2WPage, and er::directtoweb::interfaces::ERDQueryPageInterface.Inherited by ERD2WQueryPageWithFetchSpecification, ERD2WQueryPageTemplate, ERD2WQueryPageWithFetchSpecificationTemplate, ERDIVQueryPage, ERLITQueryPage, and ERNEUQueryPage.
Detailed Description
Superclass for all query pages.In addition to the rest of the goodies of ERD2WPage, it lets you save and restore the initial query bindings by supplying a NS(Mutable)Dictionary which contains the keys "queryMin", "queryMax" etc from the respective fields of the WODisplayGroup. fetchSpecificationName enableQueryForNullValues isDeep usesDistinct refrehRefetchedObjects fetchLimit prefetchingRelationshipKeyPaths showListInSamePage listConfigurationName queryDataSourceDelegate queryValidationDelegate enableQueryForNullValues canQueryPropertyForNullValues
Constructor & Destructor Documentation
| ERD2WQueryPage | ( | WOContext | context | ) |
Member Function Documentation
| void appendToResponse | ( | WOResponse | response, | |
| WOContext | context | |||
| ) |
Overridden from the parent for better logging. Reports exceptions in the console for easier debugging.
Reimplemented from ERD2WPage.
Reimplemented in ERDIVQueryPage.
| void awake | ( | ) |
Overridden to lock the page's editingContext, if there is any present.
Reimplemented from ERD2WPage.
| WOComponent cancelAction | ( | ) |
| boolean canQueryCurrentPropertyForNullValue | ( | ) |
Determines if the null query checkbox can be shown for the current D2W property key should be checked.
- Returns:
- true if the checkbox should be checked
| WOComponent clearAction | ( | ) |
| void createDisplayGroup | ( | ) | [protected] |
| EODataSource defaultQueryDataSource | ( | ) |
Default implementation of which assembles the data source for the search results page, configured for the current query.
- Returns:
- the prepared data source
| WODisplayGroup displayGroup | ( | ) |
Gets the display group.
- Returns:
- the display group
| int fetchLimit | ( | ) |
| EOFetchSpecification fetchSpecification | ( | ) |
| String fetchSpecificationName | ( | ) |
| String headerTemplate | ( | ) |
| boolean isDeep | ( | ) |
| boolean isNullQueryCheckedForCurrentProperty | ( | ) |
Determines if the null query checkbox for the current D2W property key should be checked.
- Returns:
- true if the checkbox should be checked
| void loadQueryBindings | ( | ) | [protected] |
| NSArray nullablePropertyKeys | ( | ) |
Discovers the property keys that can be queried for a NULL value.
- Returns:
- the array of nullable and/or non-mandatory property keys

| void pullQueryBindingsForName | ( | String | name | ) | [protected] |
| void pushQueryBindingsForName | ( | String | name | ) | [protected] |
| EOQualifier qualifier | ( | ) |
| WOComponent queryAction | ( | ) |
Reimplemented in ERMODQueryPage.
| NSDictionary queryBindings | ( | ) |
| EODataSource queryDataSource | ( | ) |
Assembles the data source for the search results page, configured for the current query. If a queryDataSourceDelegate() is defined, the delegate's implementation is invoked. Otherwise, the defaultQueryDataSource() is returned.
- Returns:
- the prepared data source
Implements ERDQueryPageInterface.
Gets the query data source delegate.
- Returns:
- the query data source delegate
| EOFetchSpecification queryFetchSpecification | ( | ) |
Gets the query validation delegate.
- Returns:
- the query validation delegate
| boolean refreshRefetchedObjects | ( | ) |
| WOComponent returnAction | ( | ) |
Reimplemented in ERMODQueryPage.
| void saveQueryBindings | ( | ) | [protected] |
| void setCancelDelegate | ( | NextPageDelegate | cancelDelegate | ) |
Implements ERDQueryPageInterface.
| void setFetchSpecification | ( | EOFetchSpecification | value | ) |
| void setFetchSpecificationName | ( | String | value | ) |
| void setIsNullQueryCheckedForCurrentProperty | ( | boolean | value | ) |
Sets the flag denoting a property key is being queried for a null value.
- Parameters:
-
value of the checkbox' checked attribute
| void setQueryBindings | ( | NSDictionary | dictionary | ) |
| void setQueryDataSource | ( | EODataSource | datasource | ) |
Sets the query data source.
- Parameters:
-
datasource to be used as the query data source
| void setQueryDataSourceDelegate | ( | ERDQueryDataSourceDelegateInterface | delegate | ) |
Sets the query data source delegate.
- Parameters:
-
delegate to use as the query data source delegate
Set a search value for the display group query match. When the value is null is gets removed from the dict, when the operator is null and the value isn't, "=" is chosen. When operator is "<" is uses queryMatch(), if it is ">" is uses queryMin(), so you can use it with the various date range components.
- Parameters:
-
value to assign to the queryMatch dictionary for the given key operator used for comparing the value key to use
Implements ERDQueryPageInterface.
| void setQueryValidationDelegate | ( | ERDQueryValidationDelegate | delegate | ) |
Sets the query validation delegate.
- Parameters:
-
delegate to use as the query validation delegate
| void setShowResults | ( | boolean | value | ) |
| boolean showCancel | ( | ) |
| boolean showResults | ( | ) |
| void substituteValueForNullableQueryKeys | ( | ) | [protected] |
When querying for properties with a null value, and the null value checkbox for a property key is checked, this method substitutes NSKeyValueCoding.NullValue into the display group's query dictionaries for that property key.
| void takeValuesFromRequest | ( | WORequest | r, | |
| WOContext | c | |||
| ) |
Overridden from the parent for better logging. Also clears validation errors
Reimplemented from ERD2WPage.
| boolean usesDistinct | ( | ) |
