Example 1 with MappingRelationshipElement

the class DatabaseGenerator method addInverseMappingRelationship.

/**
 * Create and add MappingRelationship with local inverse column pair
 * (for join table) or inverse column pair

 * It is for column pairs between local table and join table
 * or for column pairs between local table and foreign table (contains
 * foreign key)
 * The column pair for mappingRelationship is inverse order
 * as the column pair from foreign key. Foreign key is not in the passing
 * mapping class but in the inverse mapping class

 * @param mappingClass mapping class that holds the relationship
 * @param fkeyForeign holding column pair information for the relationship
