Method Detail

equals

public boolean equals(java.util.Map.Entry other)

equals

public boolean equals(java.lang.Object other)

Specified by:

equals in interface java.util.Map.Entry

Overrides:

equals in class java.lang.Object

getKey

public K getKey()

Returns the key corresponding to this entry.

Specified by:

getKey in interface java.util.Map.Entry

Returns:

the key corresponding to this entry

Throws:

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

getValue

public V getValue()

Returns the value corresponding to this entry. If the mapping has been removed from the backing map (by the iterator's remove operation), the results of this call are undefined.

Specified by:

getValue in interface java.util.Map.Entry

Returns:

the value corresponding to this entry

Throws:

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

hashCode

public int hashCode()

Specified by:

hashCode in interface java.util.Map.Entry

Overrides:

hashCode in class java.lang.Object

setValue

public V setValue(java.lang.Object value)

Replaces the value corresponding to this entry with the specified value (optional operation). (Writes through to the map.) The behavior of this call is undefined if the mapping has already been removed from the map (by the iterator's remove operation).

Specified by:

setValue in interface java.util.Map.Entry

Parameters:

value - new value to be stored in this entry

Returns:

old value corresponding to the entry

Throws:

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.
