All Implemented Interfaces:

Map.Entry

Enclosing class:

WeakHashMap.WeakBucket

---

class WeakHashMap.WeakBucket.WeakEntry

extends java.lang.Object

implements Map.Entry

This class gives the Entry representation of the current bucket. It also keeps a strong reference to the key; bad things may happen otherwise.

---

Field Summary
(package private)  java.lang.Object	key           The strong ref to the key.

 

Constructor Summary

WeakHashMap.WeakBucket.WeakEntry(java.lang.Object key)           Creates a new entry for the key.

 

Method Summary
boolean	equals(java.lang.Object o)           The equals method as specified in the Entry interface.
WeakHashMap.WeakBucket	getBucket()           Returns the underlying bucket.
java.lang.Object	getKey()           Returns the key.
java.lang.Object	getValue()           Returns the value.
int	hashCode()           The hashCode as specified in the Entry interface.
java.lang.Object	setValue(java.lang.Object newVal)           This changes the value.

Field Detail

key

java.lang.Object key

The strong ref to the key.

Constructor Detail

WeakHashMap.WeakBucket.WeakEntry

public WeakHashMap.WeakBucket.WeakEntry(java.lang.Object key)

Creates a new entry for the key.

Method Detail

getBucket

public WeakHashMap.WeakBucket getBucket()

Returns the underlying bucket.

---

getKey

public java.lang.Object getKey()

Returns the key.

Specified by:

getKey in interface Map.Entry

---

getValue

public java.lang.Object getValue()

Returns the value.

Specified by:

getValue in interface Map.Entry

---

setValue

public java.lang.Object setValue(java.lang.Object newVal)

This changes the value. This change takes place in the underlying hash map.

Specified by:

setValue in interface Map.Entry

---

hashCode

public int hashCode()

The hashCode as specified in the Entry interface.

Specified by:

hashCode in interface Map.Entry

---

equals

public boolean equals(java.lang.Object o)

The equals method as specified in the Entry interface.

Specified by:

equals in interface Map.Entry

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
