Interface ColumnRefStructuredType

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

ColumnRefStructuredType$Hib

public interface ColumnRefStructuredType
extends RefAssociation

ColumnRefStructuredType association proxy interface. Associates Columns of a StructuredType with the Type they reference in the REF clause

Note: This type should not be subclassed, implemented or directly instantiated by clients. It is generated from a MOF metamodel and implemented by Enki or MDR.

Method Summary

boolean	add(CwmSqlstructuredType referencedTableType, CwmColumn referencingColumn) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmSqlstructuredType referencedTableType, CwmColumn referencingColumn) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmSqlstructuredType	getReferencedTableType(CwmColumn referencingColumn) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
Collection<CwmColumn>	getReferencingColumn(CwmSqlstructuredType referencedTableType) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmSqlstructuredType referencedTableType, CwmColumn referencingColumn) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmSqlstructuredType referencedTableType,
               CwmColumn referencingColumn)

Queries whether a link currently exists between a given pair of instance objects in the associations link set.

Parameters:

referencedTableType - Value of the first association end.

referencingColumn - Value of the second association end.

Returns:

Returns true if the queried link exists.

getReferencedTableType

CwmSqlstructuredType getReferencedTableType(CwmColumn referencingColumn)

Queries the instance object that is related to a particular instance object by a link in the current associations link set.

Parameters:

referencingColumn - Required value of the second association end.

Returns:

Related object or null if none exists.

getReferencingColumn

Collection<CwmColumn> getReferencingColumn(CwmSqlstructuredType referencedTableType)

Queries the instance objects that are related to a particular instance object by a link in the current associations link set.

Parameters:

referencedTableType - Required value of the first association end.

Returns:

Collection of related objects.

add

boolean add(CwmSqlstructuredType referencedTableType,
            CwmColumn referencingColumn)

Creates a link between the pair of instance objects in the associations link set.

Parameters:

referencedTableType - Value of the first association end.

referencingColumn - Value of the second association end.

remove

boolean remove(CwmSqlstructuredType referencedTableType,
               CwmColumn referencingColumn)

Removes a link between a pair of instance objects in the current associations link set.

Parameters:

referencedTableType - Value of the first association end.

referencingColumn - Value of the second association end.
