Class FastMap.Entry<K,V>

java.lang.Object

javolution.util.FastMap.Entry<K,V>

All Implemented Interfaces:

java.util.Map.Entry<K,V>, Realtime, FastCollection.Record

Enclosing class:

FastMap<K,V>

public static class FastMap.Entry<K,V>
extends java.lang.Object
implements java.util.Map.Entry<K,V>, FastCollection.Record, Realtime

This class represents a FastMap entry. Custom FastMap may use a derived implementation. For example:

    static class MyMap<K,V,X> extends FastMap<K,V> {
        protected MyEntry newEntry() {
            return new MyEntry();
        }
        class MyEntry extends Entry<K,V> {
            X xxx; // Additional entry field (e.g. cross references).
        }
    }

Modifier	Constructor and Description
protected	Entry() Default constructor.

Method Summary

Modifier and Type	Method and Description
boolean	equals(java.lang.Object that) Indicates if this entry is considered equals to the specified entry (using default value and key equality comparator to ensure symetry).
K	getKey() Returns the key for this entry.
FastMap.Entry<K,V>	getNext() Returns the entry after this one.
FastMap.Entry<K,V>	getPrevious() Returns the entry before this one.
V	getValue() Returns the value for this entry.
int	hashCode() Returns the hash code for this entry.
V	setValue(V value) Sets the value for this entry.
Text	toText() Returns the textual representation of this real-time object (equivalent to toString except that the returned value can be "stack" allocated and supports fast concatenation).
