I'm currently working to convert an application from using hibernate mapping files (.hbm.xml) to hibernate/jpa annotations (with a jpa annotation preference).
I am running into these two attributes in some of the hibernate mapping files on one-to-one relationships:
constrained="true"|"false"
outer-join="true"|"false"
I have been heavily researching these two but I cannot find a straight answer.
It seems that optional="true"|"false" can handle the both of them, but it feels wrong to accept this as the answer without a reference from documentation or an official source.
