Method Details

from

<X> BlazeRoot<X> from(Class<X> entityClass,
 String alias)

Like AbstractQuery.from(Class) but allows to set the alias of the BlazeRoot.

Type Parameters:

X - The entity type

Parameters:

alias - The alias for the BlazeRoot

Returns:

query root corresponding to the given entity

from

<X> BlazeRoot<X> from(javax.persistence.metamodel.EntityType<X> entityType,
 String alias)

Parameters:

entityType - the entity type

alias - The alias for the BlazeRoot

Returns:

query root corresponding to the given entity
