Package org.apache.avro.util
Class MapEntry<K,V>
java.lang.Object
org.apache.avro.util.MapEntry<K,V>
- Type Parameters:
K
- Key of the map-entryV
- Value of the map-entry
- All Implemented Interfaces:
Map.Entry<K,
V>
An implementation of
Map.Entry
with well-defined member names.
Using this class helps make Avro immune from the naming variations of
key/value fields among several Map.Entry
implementations. If objects
of this class are used instead of the regular ones obtained by
Map.entrySet()
, then we need not worry about the actual field names
or any changes to them in the future.
Example: ConcurrentHashMap.MapEntry
does not name the fields as key/
value in Java 1.8 while it used to do so in Java 1.7
