eu.stratosphere.api.java.tuple.Tuple3

A tuple with 3 fields. Tuples are strongly typed; each field may be of a separate type. The fields of the tuple can be accessed directly as public fields (f0, f1, ...) or via their position through the {@link #getField(int)} method. The tuple field positions start at zero.

Tuples are mutable types, meaning that their fields can be re-assigned. This allows functions that work with Tuples to reuse objects in order to reduce pressure on the garbage collector. @see Tuple @param < T0> The type of field 0 @param < T1> The type of field 1 @param < T2> The type of field 2
