Class StrongKeyEntry<T,K>

java.lang.Object
  org.semanticweb.elk.util.collections.entryset.StrongKeyEntry<T,K>

Type Parameters:

T - the type of the keys for linked entries

K - the type of the key of this entry

All Implemented Interfaces:

KeyEntry<T,K>

public abstract class StrongKeyEntry<T,K>
extends Object
implements KeyEntry<T,K>

A prototype class for entries with keys. Sub-classes should implement the method for computing the equality function for the entry and hash code of the keys, which will be used for initializing the hash code of the entry. The hashCode and equals method should be compatible as usual.

Method Detail

getKey

public K getKey()

Specified by:

getKey in interface KeyEntry<T,K>

setNext

public void setNext(KeyEntry<T,? extends T> next)

Setting the input element as the next element of the entry.

Parameters:

next - the object that should be set as the next element of the record

getNext

public KeyEntry<T,? extends T> getNext()

Returns the next next element of the entry, or null if there is no next element

Returns:

Overrides:

hashCode in class Object

computeHashCode

public abstract int computeHashCode()

Compute the value which will be used as a final hash code for this object. Must be compatible with the equals(Object) method usual.

Returns:

the value which will be used as a hash code for this object

equals

public abstract boolean equals(Object object)

Overrides:

equals in class Object
