public static class: AbstractMap.SimpleImmutableEntry [javadoc | source]

All Implemented Interfaces:
    Entry, Serializable

An Entry maintaining an immutable key and value. This class does not support method setValue. This class may be convenient in methods that return thread-safe snapshots of key-value mappings.
 public SimpleImmutableEntry(Entry<? extends K, ? extends V> entry) 
    Creates an entry representing the same mapping as the specified entry.
    entry - the entry to copy
 public SimpleImmutableEntry(K key,
    V value) 
Method from java.util.AbstractMap$SimpleImmutableEntry Summary:
equals,   getKey,   getValue,   hashCode,   setValue,   toString
Methods from java.lang.Object:
clone,   equals,   finalize,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait
Method from java.util.AbstractMap$SimpleImmutableEntry Detail:
 public boolean equals(Object o) 
    Compares the specified object with this entry for equality. Returns {@code true} if the given object is also a map entry and the two entries represent the same mapping. More formally, two entries {@code e1} and {@code e2} represent the same mapping if
      (e1.getKey()==null ?
       e2.getKey()==null :
      (e1.getValue()==null ?
       e2.getValue()==null :
    This ensures that the {@code equals} method works properly across different implementations of the {@code Map.Entry} interface.
 public K getKey() 
    Returns the key corresponding to this entry.
 public V getValue() 
    Returns the value corresponding to this entry.
 public int hashCode() 
    Returns the hash code value for this map entry. The hash code of a map entry {@code e} is defined to be:
      (e.getKey()==null   ? 0 : e.getKey().hashCode()) ^
      (e.getValue()==null ? 0 : e.getValue().hashCode())
    This ensures that {@code e1.equals(e2)} implies that {@code e1.hashCode()==e2.hashCode()} for any two Entries {@code e1} and {@code e2}, as required by the general contract of Object#hashCode .
 public V setValue(V value) 
    Replaces the value corresponding to this entry with the specified value (optional operation). This implementation simply throws UnsupportedOperationException, as this class implements an immutable map entry.
 public String toString() 
    Returns a String representation of this map entry. This implementation returns the string representation of this entry's key followed by the equals character ("=") followed by the string representation of this entry's value.
