Method Detail

areEqual

boolean areEqual()

Returns:

true if there are no differences between the two maps; that is, if the maps are equal.

entriesOnlyOnLeft

Map<K,V> entriesOnlyOnLeft()

Returns:

an unmodifiable map containing the entries from the left map whose keys are not present in the right map.

entriesOnlyOnRight

Map<K,V> entriesOnlyOnRight()

Returns:

an unmodifiable map containing the entries from the right map whose keys are not present in the left map.

entriesInCommon

Map<K,V> entriesInCommon()

Returns:

an unmodifiable map containing the entries that appear in both maps; that is, the intersection of the two maps.

entriesDiffering

Map<K,MapDifference.ValueDifference<V>> entriesDiffering()

Returns:

an unmodifiable map describing keys that appear in both maps, but with different values.

equals

boolean equals(Object object)

Compares the specified object with this instance for equality. Returns true if the given object is also a MapDifference and the values returned by the entriesOnlyOnLeft(), entriesOnlyOnRight(), entriesInCommon() and entriesDiffering() of the two instances are equal.

Overrides:

equals in class Object

hashCode

int hashCode()

Returns the hash code for this instance. This is defined as the hash code of

 
 Arrays.asList(entriesOnlyOnLeft(), entriesOnlyOnRight(),
         entriesInCommon(), entriesDiffering())
 
 

Overrides:

hashCode in class Object
