How do I figure out the cardinality of the source end, for a unidirectional
relation (opposite = null)
So I was doing something like this (still rough)
«IF opposite != null»
«REM»Bi-directional«ENDREM»
«IF this.many && !opposite.many»
@javax.persistence.OneToMany(mappedBy="«opposite.name.toFirstLower()»")
«ELSEIF this.many && opposite.many»
@javax.persistence.ManyToMany(mappedBy="«opposite.name.toFirstLower()»")
«ELSEIF !this.many && !opposite.many»
@javax.persistence.OneToOne
@javax.persistence.JoinColumn(name="«getForeignKeyName()»")
«ELSEIF !this.many && opposite.many»
@javax.persistence.ManyToOne
@javax.persistence.JoinColumn(name="«getForeignKeyName()»")
«ENDIF»
«ELSE»
«REM»Uni-directional«ENDREM»
«IF this.many && the source is not many»
@javax.persistence.OneToMany
«ELSEIF this.many && source is many»
@javax.persistence.ManyToMany
«ELSEIF !this.many && source is not many»
@javax.persistence.OneToOne
«ELSEIF !this.many && source is many»
@javax.persistence.ManyToOne
@javax.persistence.JoinColumn(name="«getForeignKeyName()»")
«ENDIF»
«ENDIF»
The bold parts in ELSE I need to fix further...
