F - the type of the first object, which must be SerializableS - the type of the second object, which must be Serializablepublic class Pair<F extends Serializable,S extends Serializable> +extends Object +implements Serializable+
+ The two objects of the pair must be serializable and can be of the same
+ type.
+
+ Note that this class is not intended to be used as a general-purpose pair and should only be + used when interfacing with the extractor. +
| Constructor and Description | +

+
F |
+getFirst()
+Gets the first object of the pair.
+ |
+
S |
+getSecond()
+Gets the second object of the pair.
+ |
+
int |
+hashCode()
+Returns a hash code of the current
