Examples of TupleFactory

eu.admire.ogsadai.activity.block.TupleFactory
kodkod.instance.TupleFactory
A factory class that facilitates creation of tuples and tuple sets drawn from a given universe. Only one factory per universe exists. @specfield universe: Universe @invariant no f: TupleFactory - this | f.universe = this.universe @author Emina Torlak
org.apache.crunch.types.TupleFactory
org.apache.openjpa.persistence.TupleFactory
A factory for tuples such that all instances created by a factory instance share the same TupleElements to save memory consumption.
All Tuple instances created by this factory access the TupleElememts contained in this factory. @author Pinaki Poddar @since 2.0.0
org.apache.pig.data.TupleFactory
A factory to construct tuples. This class is abstract so that users can override the tuple factory if they desire to provide their own that returns their implementation of a tuple. If the property pig.data.tuple.factory.name is set to a class name and pig.data.tuple.factory.jar is set to a URL pointing to a jar that contains the above named class, then {@link #getInstance()} will create aan instance of the named class using the indicated jar. Otherwise, it will create an instance of {@link DefaultTupleFactory}.
