com.bigdata.btree
Class BigdataMap.Entry

java.lang.Object
  com.bigdata.btree.BigdataMap.Entry

All Implemented Interfaces:

Map.Entry<K,V>

Enclosing class:

BigdataMap<K,V>

protected class BigdataMap.Entry
extends Object
implements Map.Entry<K,V>

Note: Since the same ITuple instance is returned for each tuple by many ITupleIterators there is a side-effect that invalidates the last visited BigdataMap.Entry object. This side-effect could be removed by eagerly materializing the key and value from the ITuple rather than doing it lazily but that maps the Map interface either blow up (the key can not be recovered), do more work for cases where the key is going to be stored in the value, and work efficiently only for those cases where the key can be directly decoded, e.g., int, long, float, double, etc.
