fetch

public Select<T> fetch(java.lang.Runnable joinCondition)

fetch is used to load detail objects. In most case, you probably want to use leftFetch because if the master instance does not have detail instances, it will not be returned whereas for leftFetch the master instance is returned.

Parameters:

joinCondition - runnable to specify the join condition

Returns:

Select instance

leftFetch

public Select<T> leftFetch(java.lang.Runnable joinCondition)

See description on fetch.

Parameters:

joinCondition - runnable to specify the join condition

Returns:

Select instance

fetch

protected Select<T> fetch(javax.persistence.criteria.JoinType type,
                          java.lang.Runnable joinCondition)

setMaxResults

public Select<T> setMaxResults(int maxResults)

count

public void count()

asc

public Select<T> asc(java.lang.Runnable runnable)

desc

public Select<T> desc(java.lang.Runnable runnable)

sum

public <N extends java.lang.Number> javax.persistence.criteria.Expression<N> sum(java.lang.String attribute)

coalesce

public <N> javax.persistence.criteria.Expression coalesce(javax.persistence.criteria.Expression<N> expression,
                                                          N value)
