Subinterfaces of Join in javax.persistence.criteria
Modifier and Type	Interface	Description
`interface`	`CollectionJoin<Z,E>`	The `CollectionJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Collection`.
`interface`	`ListJoin<Z,E>`	The `ListJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.List`.
`interface`	`MapJoin<Z,K,V>`	The `MapJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Map`.
`interface`	`PluralJoin<Z,C,E>`	The `PluralJoin` interface defines functionality that is common to joins to all collection types.
`interface`	`SetJoin<Z,E>`	The `SetJoin` interface is the type of the result of joining to a collection over an association or element collection that has been specified as a `java.util.Set`.
