Package org.apache.sis.util.collection

Class DerivedMap.InvertibleValue<SK,SV,K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.apache.sis.util.collection.DerivedMap<SK,SV,K,V>

org.apache.sis.util.collection.DerivedMap.InvertibleValue<SK,SV,K,V>

Type Parameters:

SK - the type of keys in the storage map.

SV - the type of values in the storage map.

K - the type of keys in this map.

V - the type of values in this map.

All Implemented Interfaces:

Serializable, Function<Map.Entry<SK,SV>,Map.Entry<K,V>>, Map<K,V>, ObjectConverter<Map.Entry<SK,SV>,Map.Entry<K,V>>

Enclosing class:

DerivedMap<SK,SV,K,V>

private static final class DerivedMap.InvertibleValue<SK,SV,K,V>
extends DerivedMap<SK,SV,K,V>

A DerivedMap used when the DerivedMap.valueConverter is invertible. Availability of the inverse conversion allows us to delegate some operations to the DerivedMap.storage map instead of iterating over all entries.
