Method Detail

treatAs

<T extends E> BlazeCollectionJoin<Z,T> treatAs(java.lang.Class<T> type)

Like BlazeJoin.treatAs(java.lang.Class<T>) but returns the subtype BlazeCollectionJoin instead.

Specified by:

treatAs in interface BlazeJoin<Z,E>

Type Parameters:

T - The target treat type

Parameters:

type - type to be downcast to

Returns:

The treated join object

on

BlazeCollectionJoin<Z,E> on(Expression<java.lang.Boolean> restriction)

Modify the join to restrict the result according to the specified ON condition. Replaces the previous ON condition, if any. Return the join object

Specified by:

on in interface BlazeJoin<Z,E>

Parameters:

restriction - a simple or compound boolean expression

Returns:

the modified join object

on

BlazeCollectionJoin<Z,E> on(Predicate... restrictions)

Modify the join to restrict the result according to the specified ON condition. Replaces the previous ON condition, if any. Return the join object

Specified by:

on in interface BlazeJoin<Z,E>

Parameters:

restrictions - zero or more restriction predicates

Returns:

the modified join object
