Method Detail

areEqual

public boolean areEqual()

Description copied from interface: MapDifference

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

Specified by:

areEqual in interface MapDifference<K,V>

entriesOnlyOnLeft

public java.util.Map<K,V> entriesOnlyOnLeft()

Description copied from interface: MapDifference

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

Specified by:

entriesOnlyOnLeft in interface MapDifference<K,V>

entriesOnlyOnRight

public java.util.Map<K,V> entriesOnlyOnRight()

Description copied from interface: MapDifference

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

Specified by:

entriesOnlyOnRight in interface MapDifference<K,V>

entriesInCommon

public java.util.Map<K,V> entriesInCommon()

Description copied from interface: MapDifference

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