Interface RelationshipStrategy

All Superinterfaces:

IAdaptable, JpaContextNode, JpaNode, JptResourceTypeReference, Model, ReadOnlyRelationshipStrategy

All Known Subinterfaces:

JavaJoinColumnRelationshipStrategy, JavaJoinTableRelationshipStrategy, JavaPrimaryKeyJoinColumnRelationshipStrategy, JoinColumnRelationshipStrategy, JoinTableRelationshipStrategy, MappedByRelationshipStrategy, MappingRelationshipStrategy2_0, OrmJoinColumnRelationshipStrategy, OrmJoinTableRelationshipStrategy, OrmPrimaryKeyJoinColumnRelationshipStrategy, PrimaryKeyJoinColumnRelationshipStrategy

public interface RelationshipStrategy
extends ReadOnlyRelationshipStrategy

Strategy describing how two entities are joined, either for a RelationshipMapping or an AssociationOverride:

• join column
• join table
• "mapped by"
• primary key join column

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.

Since:

2.2

Method Detail

getRelationship

Relationship getRelationship()

Description copied from interface: ReadOnlyRelationshipStrategy

Return the strategy's relationship.

Specified by:

getRelationship in interface ReadOnlyRelationshipStrategy

addStrategy

void addStrategy()

Add this strategy to the relationship.

removeStrategy

void removeStrategy()

Remove this strategy from the relationship.

isOverridable

boolean isOverridable()

Return whether the relationship's mapping can be overridden with an association override.

resolveDbTable

Table resolveDbTable(String tableName)

Return the database table for the specified table name.

tableNameIsInvalid

boolean tableNameIsInvalid(String tableName)

Return whether the specified table cannot be explicitly specified in the column's table element.

getColumnTableNotValidDescription

String getColumnTableNotValidDescription()

Return a message description used when the column's table is not valid in this context. This will be passed in as a parameter to a validation message. Here is an example where the description is what is returned by the implementation:

location: Table "table name" for map key column "column name"

description: does not match join table
