Method Detail

get

int get(long key)

Returns:

the value for the specified key if this map contains key key. Otherwise returns default value.

containsKey

boolean containsKey(long key)

Returns:

true if this map contains key key. Otherwise false

containsKeys

boolean containsKeys(LongIterable keys)

Returns:

true if this map contains all of the elements produced by keys. Otherwise false

size

int size()

Returns:

the number of keys/values in this map(its cardinality)

isEmpty

boolean isEmpty()

Returns:

true if this map contains no elements

keysIterator

LongIterator keysIterator()

valuesIterator

IntIterator valuesIterator()

keySet

LongSet keySet()

Returns:

a LongSet view of the keys contained in this map.

equals

boolean equals(java.lang.Object o)

Compares the specified object with this map for equality. Returns true if and only if the specified object is also a LongIntMap and both objects contain exactly the same key-value pairs, regardless of their order

Overrides:

equals in class java.lang.Object

hashCode

int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code of elements stored in the map. The hash code is defined as a sum of hash codes of keys and values stored within the map. Because addition is commutative, this ensures that different order of elements in a map does not affect the hash code.
