equals back to summary

equals	back to summary
public static <K, V> boolean equals(UnmodifiableEconomicMap<K, V> lhs, UnmodifiableEconomicMap<K, V> rhs) Compares maps for equality. The maps are equal iff they share the same `equivalence strategy`, their keys are equal with respect to the strategy and the values are equal as determined by the `equals` method. Parameters lhs:UnmodifiableEconomicMap<K, V> the first map to be compared rhs:UnmodifiableEconomicMap<K, V> the second map to be compared Returns:boolean `true` iff the maps are equal Since 23.0

public static <K, V> boolean equals(UnmodifiableEconomicMap<K, V> lhs, UnmodifiableEconomicMap<K, V> rhs)

Compares maps for equality. The maps are equal iff they share the same equivalence strategy, their keys are equal with respect to the strategy and the values are equal as determined by the equals method.

Parameters

lhs:UnmodifiableEconomicMap<K, V>: the first map to be compared
rhs:UnmodifiableEconomicMap<K, V>: the second map to be compared

Returns:boolean

true iff the maps are equal

hashCode	back to summary
public static <K, V> int hashCode(UnmodifiableEconomicMap<K, V> map) Computes an order-independent hash code for an `EconomicMap`. Parameters map:UnmodifiableEconomicMap<K, V> the input map or `null` Returns:int the hash code of the map Since 23.0

public static <K, V> int hashCode(UnmodifiableEconomicMap<K, V> map)

Computes an order-independent hash code for an EconomicMap.

Parameters

keySet back to summary

keySet	back to summary
public static <K, V> EconomicSet<K> keySet(EconomicMap<K, V> map) Returns an `EconomicSet` of the keys contained in a map. Parameters map:EconomicMap<K, V> the input map Returns:EconomicSet<K> an `EconomicSet` of the keys contained in a map Since 23.0

public static <K, V> EconomicSet<K> keySet(EconomicMap<K, V> map)

Returns an EconomicSet of the keys contained in a map.

Parameters

map:EconomicMap<K, V>: the input map

Returns:EconomicSet<K>

an EconomicSet of the keys contained in a map

lexicographicalComparator back to summary

lexicographicalComparator	back to summary
public static <K, V> Comparator<UnmodifiableEconomicMap<K, V>> lexicographicalComparator(Comparator<K> keyComparator, Comparator<V> valueComparator) Creates a lexicographical map comparator using the provided key and value comparators. The maps are treated as if they were lists with the structure `{key1, value1, key2, value2, ...}`. The comparison starts by comparing their `key1` and if they are equal, it goes on to compare `value1`, then `key2`, `value2` and so on. If one of the maps is shorter, the comparators are called with `null` values in place of the missing keys/values. Parameters keyComparator:Comparator<K> a comparator to compare keys valueComparator:Comparator<V> a comparator to compare values Returns:Comparator<UnmodifiableEconomicMap<K, V>> a lexicographical map comparator Since 23.0

public static <K, V> Comparator<UnmodifiableEconomicMap<K, V>> lexicographicalComparator(Comparator<K> keyComparator, Comparator<V> valueComparator)

Creates a lexicographical map comparator using the provided key and value comparators. The maps are treated as if they were lists with the structure {key1, value1, key2, value2, ...}. The comparison starts by comparing their key1 and if they are equal, it goes on to compare value1, then key2, value2 and so on. If one of the maps is shorter, the comparators are called with null values in place of the missing keys/values.

Parameters

keyComparator:Comparator<K>: a comparator to compare keys
valueComparator:Comparator<V>: a comparator to compare values

Returns:Comparator<UnmodifiableEconomicMap<K, V>>

a lexicographical map comparator
