protected AbstractMapEntry(Object key,
    Object value) 
{
        super(key, value);
}

Constructs a new entry with the given key and given value.

Parameters:

key - the key for the entry, may be null

value - the value for the entry, may be null

 public boolean equals(Object obj) 
{
        if (obj == this) {
            return true;
        }
        if (obj instanceof Map.Entry == false) {
            return false;
        }
        Map.Entry other = (Map.Entry) obj;
        return
            (getKey() == null ? other.getKey() == null : getKey().equals(other.getKey())) &&
            (getValue() == null ? other.getValue() == null : getValue().equals(other.getValue()));
}

Compares this Map.Entry with another Map.Entry.

Implemented per API documentation of java.util.Map.Entry#equals(Object)

 public int hashCode() 
{
        return (getKey() == null ? 0 : getKey().hashCode()) ^
               (getValue() == null ? 0 : getValue().hashCode());
}

Gets a hashCode compatible with the equals method.

Implemented per API documentation of java.util.Map.Entry#hashCode()

 public Object setValue(Object value) 
{
        Object answer = this.value;
        this.value = value;
        return answer;
}

Sets the value stored in this Map.Entry.

This Map.Entry is not connected to a Map, so only the local data is changed.
