org.objectstyle.cayenne.access.util
Class SortHandler  

java.lang.Object
  org.objectstyle.cayenne.access.util.SortHandler

---

public class SortHandler

extends java.lang.Object

Defines a set of sorting methods based on object dependencies. The actual dependency tracking algorithm is pluggable via a sporter class.

---

Field Summary
protected static java.lang.Class	defaultSorterClass
protected  DependencySorter	sorter

 

Constructor Summary

SortHandler(java.lang.Class sorterClass, org.objectstyle.cayenne.access.QueryEngine queryEngine, org.objectstyle.cayenne.map.DataMap[] dataMaps)           Creates SortHandler with a specified sorter class.

SortHandler(org.objectstyle.cayenne.access.QueryEngine queryEngine, org.objectstyle.cayenne.map.DataMap[] dataMaps)           Constructor for SortHandler.

 

Method Summary
static java.lang.Class	getDefaultSorterClass()
static void	setDefaultSorterClass(java.lang.Class defaultSorterClass)           Sets the class of the sorter that should be used as a source of dependency sorting algorithms.
java.util.List	sortedDbEntitiesInDeleteOrder(java.util.List dbEntities)           Returns a new list containing all the DbEntities in entities, in the correct order for deleting objects from or removing the tables of, those entities.
java.util.List	sortedDbEntitiesInInsertOrder(java.util.List dbEntities)           Returns a new list containing all the DbEntities in entities, in the correct order for inserting objects int,o or creating the tables of, those entities.
java.util.List	sortedQueries(java.util.List unsortedQueries)           Creates and returns an array of queries in the right sorting order from an unsorted array.
void	sortObjectsInDeleteOrder(java.util.List objects)           Sorts an unsorted array of DataObjects in the right delete order for database constraints not to be violated, and so that master pk's for dependent relationships are in place prior to being needed for the dependent object and reflexive relationships are correctly handled
void	sortObjectsInInsertOrder(java.util.List objects)           Sorts an unsorted array of DataObjects in the right insert order for database constraints not to be violated, and so that master pk's for dependent relationships are in place prior to being needed for the dependent object, and reflexive relationships are correctly handled

                   org.objectstyle.cayenne.access.QueryEngine queryEngine,
                   org.objectstyle.cayenne.map.DataMap[] dataMaps)

Creates SortHandler with a specified sorter class.

Method Detail

getDefaultSorterClass

public static java.lang.Class getDefaultSorterClass()

---

setDefaultSorterClass

public static void setDefaultSorterClass(java.lang.Class defaultSorterClass)

Sets the class of the sorter that should be used as a source of dependency sorting algorithms. Class must be an instance of DependencySorter and must have a default no-argument constructor.

---

sortedQueries

public java.util.List sortedQueries(java.util.List unsortedQueries)

Creates and returns an array of queries in the right sorting order from an unsorted array.

---

sortedDbEntitiesInInsertOrder

public java.util.List sortedDbEntitiesInInsertOrder(java.util.List dbEntities)

Returns a new list containing all the DbEntities in entities, in the correct order for inserting objects int,o or creating the tables of, those entities.

---

sortedDbEntitiesInDeleteOrder

public java.util.List sortedDbEntitiesInDeleteOrder(java.util.List dbEntities)

Returns a new list containing all the DbEntities in entities, in the correct order for deleting objects from or removing the tables of, those entities.

---

sortObjectsInInsertOrder

public void sortObjectsInInsertOrder(java.util.List objects)

Sorts an unsorted array of DataObjects in the right insert order for database constraints not to be violated, and so that master pk's for dependent relationships are in place prior to being needed for the dependent object, and reflexive relationships are correctly handled

---

sortObjectsInDeleteOrder

public void sortObjectsInDeleteOrder(java.util.List objects)

Sorts an unsorted array of DataObjects in the right delete order for database constraints not to be violated, and so that master pk's for dependent relationships are in place prior to being needed for the dependent object and reflexive relationships are correctly handled
