extends Object
implements Serializable Map.Entry <K, V>
java.lang.Object
   ↳ java.util.AbstractMap.SimpleImmutableEntry<K, V>

Class Overview

An immutable key-value mapping. Despite the name, this class is non-final and its subclasses may be mutable.

Constructs an instance with the key and value of copyFrom .

Public Methods

public boolean equals ( Object object)

Added in API level 9

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o . See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
object the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object ; false otherwise.

public K getKey ()

Added in API level 9

Returns the key.

Returns
  • the key

public V getValue ()

Added in API level 9

Returns the value.

Returns
  • the value

public int hashCode ()

Added in API level 9

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public V setValue (V object)

Added in API level 9

This base implementation throws UnsupportedOperationException always.

Parameters
object the new value to set.
Returns
  • object the replaced value of this entry.

public String toString ()

Added in API level 9

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 

          getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • a printable representation of this object.
