public <T> T first()

bind

public GenericModel.JPAQuery bind(java.lang.String name,
                                  java.lang.Object param)

Bind a JPQL named parameter to the current query. Careful, this will also bind count results. This means that Integer get transformed into long so hibernate can do the right thing. Use the setParameter if you just want to set parameters.

setParameter

public GenericModel.JPAQuery setParameter(java.lang.String name,
                                          java.lang.Object param)

Set a named parameter for this query.
