    Modifier and Type
    Method
    Description
    boolean
    equals(Object o)
    Compares the specified object with this entry for equality.
    Object
    getKey()
    Returns the key of this entry.
    Object
    getValue()
    Get the value.
    int
    hashCode()
    Returns the hash code for this entry.
    Object
    setValue(Object value)
    Set the value of this entry (Note: In an entrySet or entrySet.iterator), unless the set or iterator is used under synchronization of the table as a whole (or you can otherwise guarantee lack of concurrent modification), setValue is not strictly guaranteed to actually replace the value field obtained via the get operation of the underlying hash table in multithreaded applications.
    String
    toString()
    Returns a string representation of this entry.

  • Method Details

    • getKey

      public Object getKey()
      Returns the key of this entry.
      Specified by:
      getKey in interface Map.Entry
      Returns:
      the key

    • getValue

      public Object getValue()
      Get the value. Note: In an entrySet or entrySet.iterator, unless the set or iterator is used under synchronization of the table as a whole (or you can otherwise guarantee lack of concurrent modification), getValue might return null, reflecting the fact that the entry has been concurrently removed. However, there are no assurances that concurrent removals will be reflected using this method.
      Specified by:
      getValue in interface Map.Entry
      Returns:
      the current value, or null if the entry has been detectably removed.

    • setValue

      public Object setValue(Object value)
      Set the value of this entry (Note: In an entrySet or entrySet.iterator), unless the set or iterator is used under synchronization of the table as a whole (or you can otherwise guarantee lack of concurrent modification), setValue is not strictly guaranteed to actually replace the value field obtained via the get operation of the underlying hash table in multithreaded applications. If iterator-wide synchronization is not used, and any other concurrent put or remove operations occur, sometimes even to other entries, then this change is not guaranteed to be reflected in the hash table. (It might, or it might not. There are no assurances either way.)
      Specified by:
      setValue in interface Map.Entry
      Parameters:
      value - the new value.
      Returns:
      the previous value, or null if entry has been detectably removed.
      Throws:
      NullPointerException - if the value is null.

    • equals

      public boolean equals(Object o)
      Compares the specified object with this entry for equality. Returns true if the given object is also a Map.Entry and has the same key and value.
      Specified by:
      equals in interface Map.Entry
      Overrides:
      equals in class Object
      Parameters:
      o - the object to compare
      Returns:
      true if equal, false otherwise

    • hashCode

      public int hashCode()
      Returns the hash code for this entry. Computed as the XOR of the hash codes of the key and value.
      Specified by:
      hashCode in interface Map.Entry
      Overrides:
      hashCode in class Object
      Returns:
      the hash code

    • toString

      public String toString()
      Returns a string representation of this entry.
      Overrides:
      toString in class Object
      Returns:
      a string representation in the form "key=value"
