Method Detail

getKey

public final K getKey()

Specified by:

getKey in interface Map.Entry<K,V>

Specified by:

getKey in class CompactMap.MapEntry<K,V>

getValue

public final V getValue()

Specified by:

getValue in interface Map.Entry<K,V>

Specified by:

getValue in class CompactMap.MapEntry<K,V>

setValue

public final V setValue(V value)

Specified by:

setValue in interface Map.Entry<K,V>

Specified by:

setValue in class CompactMap.MapEntry<K,V>

valueHashCode

protected final int valueHashCode()

Description copied from class: CompactMap.MapEntry

Used by CompactMap.MapEntry.hashCode() to return the real hashCode for the value held by this map entry.
getValue().hashCode cannot be used in general because getValue() may return this e.g. in case the value is represented by primitive data type. The method should use that real value for the hash code computation.

Specified by:

valueHashCode in class CompactMap.MapEntry<K,V>

valueEquals

protected final boolean valueEquals(Object value2)

Description copied from class: CompactMap.MapEntry

Used by CompactMap.MapEntry.equals(Object) to check whether the value held by this map entry equals to the the given value.
getValue().equals() cannot be used in general because getValue() may return this e.g. in case the value is represented by primitive data type. The method should use that real value for the operation of this method.

Specified by:

valueEquals in class CompactMap.MapEntry<K,V>

Parameters:

value2 - value to be compared with value stored in this entry. The argument may be null.

toString

public String toString()

Overrides:

toString in class Object
