Interface ReadOnlyJoinColumnRelationshipStrategy

All Superinterfaces:

IAdaptable, JpaContextNode, JpaNode, JptResourceTypeReference, Model, ReadOnlyRelationshipStrategy

All Known Subinterfaces:

public interface ReadOnlyJoinColumnRelationshipStrategy
extends ReadOnlyRelationshipStrategy

Read-only join column relationship strategy.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Method Detail

getRelationshipSource

TypeMapping getRelationshipSource()

The source of the relationship is usually the owning type mapping. In the case of a target foreign key relationship the source and target are swapped.

See Also:

isTargetForeignKey()

getRelationshipTarget

TypeMapping getRelationshipTarget()

The target of the relationship usually is the target entity. In the case of a target foreign key relationship the source and target are swapped.

See Also:

isTargetForeignKey()

isTargetForeignKey

boolean isTargetForeignKey()

Return whether this relationship is a target foreign key relationship. A one-to-many mapping with a join column will have the foreign key in the target table.

getJoinColumns

org.eclipse.jpt.common.utility.iterable.ListIterable<? extends ReadOnlyJoinColumn> getJoinColumns()

Return the join columns whether specified or default.

getJoinColumnsSize

int getJoinColumnsSize()

Return the number of join columns, whether specified and default.

getSpecifiedJoinColumns

org.eclipse.jpt.common.utility.iterable.ListIterable<? extends ReadOnlyJoinColumn> getSpecifiedJoinColumns()

Return the specified join columns.

getSpecifiedJoinColumnsSize

int getSpecifiedJoinColumnsSize()

Return the number of specified join columns.

hasSpecifiedJoinColumns

boolean hasSpecifiedJoinColumns()

Return whether the strategy has any specified join columns. (Equivalent to getSpecifiedJoinColumnsSize() != 0.)

getSpecifiedJoinColumn

ReadOnlyJoinColumn getSpecifiedJoinColumn(int index)

Return the specified join column at the specified index.

getDefaultJoinColumn

ReadOnlyJoinColumn getDefaultJoinColumn()

Return the default join column. If there are specified join columns, there is no default join column. There are also times that there may be no default join column even if there are no specified join columns.
