Method Summary

Modifier and Type	Method	Description
static DBForeignKey	create(SrvContext srvCtx, MMCreateTemplate ohTemplate, ELContainerAble ohContainer, ELElement ohRequirement)	Create a new Foreign Key (of Table) with template and container with requirement.
static DBForeignKey	create(SrvContext srvCtx, MMStereotype ohStereotype, ELContainerAble ohContainer, ELElement ohRequirement)	Create a new Foreign Key (of Table) with stereotype and container with requirement.
static DBForeignKey	createAndMaintain(SrvContext srvCtx, MMCreateTemplate ohTemplate, ELContainerAble ohContainer, ELElement ohRequirement)	Create a new Foreign Key (of Table) with template and container with requirement.
static DBForeignKey	createAndMaintain(SrvContext srvCtx, MMStereotype ohStereotype, ELContainerAble ohContainer, ELElement ohRequirement)	Create a new Foreign Key (of Table) with stereotype and container with requirement.
static java.util.List<DBForeignKey>	createByER(SrvContext srvCtx, ELContainerAble ohDBElement, MENamedElement ohERElement)	This method creates (if possible) a DBForeignKey for the given ERForeignKey (ER element) in the given DBTable (DB element).
static DBTable	mergeSiblingTables(SrvContext srvCtx, java.util.List<? extends ELElement> seq)	Merges two or more sibling database tables of the given foreign keys.
static java.util.List<DBTable>	mergeToForeign(SrvContext srvCtx, java.util.List<? extends ELElement> seq)	Merges the DBTable which contains the DBUniqueKey corresponding to the selected DBForeignKey into the DBTable which contains the foreign key. This action creates a DBMergedTable in the modified table.
static java.util.List<DBTable>	mergeToUnique(SrvContext srvCtx, java.util.List<? extends DBForeignKey> seqForeign, java.util.List<java.lang.Integer> seqCard)	Merges the DBTable of the selected DBForeignKey into the DBTable which contains the corresponding DBUniqueKey. This action creates a DBMergedTable in the modified table.

Method Detail

createByER

public static java.util.List<DBForeignKey> createByER(SrvContext srvCtx,
                                                      ELContainerAble ohDBElement,
                                                      MENamedElement ohERElement)
                                               throws InoNetException,
                                                      SrvErrorException

This method creates (if possible) a DBForeignKey for the given ERForeignKey (ER element) in the given DBTable (DB element). It could be impossible to create the foreign key, if the referenced unique key does not exist in the DB model.
This standard mapping creates a MEMappingDependency with the ER key as requirement element and with the newly created DB key as implementation element. The mapping dependency is marked as 'maintaining' for further automatic mapping maintenance.

Parameters:

srvCtx - The context of the related innovator server.

ohDBElement - Target DB Element for evaluating the owner for the new element

ohERElement - Requirement element of the ER Model

Throws:

InoNetException

SrvErrorException

mergeSiblingTables

public static DBTable mergeSiblingTables(SrvContext srvCtx,
                                         java.util.List<? extends ELElement> seq)
                                  throws InoNetException,
                                         SrvErrorException

Merges two or more sibling database tables of the given foreign keys. The foreign keys must be identifying and maximum 1, and must reference the same primary key.
This action creates a DBMergedTable in the modified table.

Parameters:

srvCtx - The context of the related innovator server.

seq - List of ELElement

Throws:

InoNetException

SrvErrorException

mergeToForeign

public static java.util.List<DBTable> mergeToForeign(SrvContext srvCtx,
                                                     java.util.List<? extends ELElement> seq)
                                              throws InoNetException,
                                                     SrvErrorException

Merges the DBTable which contains the DBUniqueKey corresponding to the selected DBForeignKey into the DBTable which contains the foreign key.
This action creates a DBMergedTable in the modified table.

Parameters:

srvCtx - The context of the related innovator server.

seq - List of ELElement

Throws:

InoNetException

SrvErrorException

mergeToUnique

public static java.util.List<DBTable> mergeToUnique(SrvContext srvCtx,
