Class EquivalentHashMap<K,V>

java.lang.Object

org.infinispan.commons.util.AbstractMap<K,V>

org.infinispan.commons.equivalence.EquivalentHashMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

Direct Known Subclasses:

EquivalentLinkedHashMap

Deprecated.

public class EquivalentHashMap<K,V>
extends AbstractMap<K,V>

Custom hash-based map which accepts no null keys nor null values, where equality and hash code calculations are done based on passed Equivalence function implementations for keys and values, as opposed to relying on their own equals/hashCode/toString implementations. This is handy when using key/values whose mentioned methods cannot be overriden, i.e. arrays, and in situations where users want to avoid using wrapper objects. This hash map implementation is optimised for store/retrieval rather than iteration. Internal node entries are not linked, so responsibility to link them falls on the iterators.

Since:

5.3
