SimpleEntry

open class SimpleEntry<K : Any!, V : Any!> : MutableEntry<K, V>, Serializable

SimpleEntry

SimpleEntry(
    key: K, 
    value: V)

Creates an entry representing a mapping from the specified key to the specified value.

Parameters
key	K: the key represented by this entry
value	V: the value represented by this entry

SimpleEntry

SimpleEntry(entry: MutableEntry<out K, out V>)

Creates an entry representing the same mapping as the specified entry.

Parameters
entry	MutableEntry<out K, out V>: the entry to copy

equals

open fun equals(other: Any?): Boolean

Compares the specified object with this entry for equality. Returns true if the given object is also a map entry and the two entries represent the same mapping. More formally, two entries e1 and e2 represent the same mapping if

(e1.getKey()==null ?
     e2.getKey()==null :
     e1.getKey().equals(e2.getKey()))
    &&
    (e1.getValue()==null ?
     e2.getValue()==null :
     e1.getValue().equals(e2.getValue()))

This ensures that the equals method works properly across different implementations of the Map.Entry interface.

Parameters
obj	the reference object with which to compare.
o	object to be compared for equality with this map entry

Return
Boolean	true if the specified object is equal to this map entry

hashCode

open fun hashCode(): Int

Returns the hash code value for this map entry. The hash code of a map entry e is defined to be:

(e.getKey()==null   ? 0 : e.getKey().hashCode()) ^
    (e.getValue()==null ? 0 : e.getValue().hashCode())

This ensures that e1.equals(e2) implies that e1.hashCode()==e2.hashCode() for any two Entries e1 and e2, as required by the general contract of Object#hashCode.

Return
Int	the hash code value for this map entry

setValue

open fun setValue(newValue: V): V

Replaces the value corresponding to this entry with the specified value.

Parameters
value	new value to be stored in this entry

Return
V	the old value corresponding to the entry

Exceptions
java.lang.UnsupportedOperationException	if the put operation is not supported by the backing map
java.lang.ClassCastException	if the class of the specified value prevents it from being stored in the backing map
java.lang.NullPointerException	if the backing map does not permit null values, and the specified value is null
java.lang.IllegalArgumentException	if some property of this value prevents it from being stored in the backing map
java.lang.IllegalStateException	implementations may, but are not required to, throw this exception if the entry has been removed from the backing map.

toString

open fun toString(): String

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.

Return
String	a String representation of this map entry

key

open val key: K

Returns the key corresponding to this entry.

Return
K	the key corresponding to this entry

Exceptions
java.lang.IllegalStateException	implementations may, but are not required to, throw this exception if the entry has been removed from the backing map.

value

open val value: V

Returns the value corresponding to this entry.

Return
V	the value corresponding to this entry

Exceptions
java.lang.IllegalStateException	implementations may, but are not required to, throw this exception if the entry has been removed from the backing map.
