Method Detail

get

double get(Object key)

Retrieves the value associated with the key. If no mapping exists for the key, the default value (usually 0) is returned.

Parameters:

key - the key

Returns:

the value associated with the key, or the default value if no such mapping exists

getOrThrow

double getOrThrow(Object key)

Retrieves the value associated with the key, throwing an IllegalStateException if no such mapping exists.

Parameters:

key - the key

Returns:

the value associated with the key

Throws:

IllegalStateException - if no mapping exists for the key

getIfAbsent

double getIfAbsent(Object key,
                   double ifAbsent)

Retrieves the value associated with the key, returning the specified default value if no such mapping exists.

Parameters:

key - the key

ifAbsent - the default value to return if no mapping exists for key

Returns:

the value associated with the key, or ifAbsent if no such mapping exists.

containsKey

boolean containsKey(Object key)

Returns whether or not the key is present in the map.

Parameters:

key - the key

Returns:

if a mapping exists in this map for the key

containsValue

boolean containsValue(double value)

Returns whether or not this map contains the value.

Parameters:

value - the value to test

Returns:

if this collection contains the value

forEachValue

void forEachValue(DoubleProcedure procedure)

Iterates through each value in this map.

Parameters:

procedure - the procedure to invoke for each value in this map.

forEachKey

void forEachKey(Procedure<? super K> procedure)

Iterates through each key in the map, invoking the procedure for each.

Parameters:

procedure - the procedure to invoke for each key

forEachKeyValue

void forEachKeyValue(ObjectDoubleProcedure<? super K> procedure)

Iterates through each key/value pair in the map, invoking the procedure for each.

Parameters:

procedure - the procedure to invoke for each key/value pair

flipUniqueValues

DoubleObjectMap<K> flipUniqueValues()

Return the DoubleObjectMap that is obtained by flipping the direction of this map and making the associations from value to key.

Throws:

IllegalStateException - if the DoubleObjectMap contains duplicate values.

Since:

9.0

select

ObjectDoubleMap<K> select(ObjectDoublePredicate<? super K> predicate)

Return a copy of this map containing only the key/value pairs that match the predicate.

Parameters:

predicate - the predicate to determine which key/value pairs in this map should be included in the returned map

Returns:

a copy of this map with the matching key/value pairs

reject

ObjectDoubleMap<K> reject(ObjectDoublePredicate<? super K> predicate)

Return a copy of this map containing only the key/value pairs that do not match the predicate.

Parameters:

predicate - the predicate to determine which key/value pairs in this map should be excluded from the returned map

Returns:

a copy of this map without the matching key/value pairs

tap

default ObjectDoubleMap<K> tap(DoubleProcedure procedure)

Specified by:

tap in interface DoubleIterable

Since:

9.0.

toString

String toString()

Follows the same general contract as AbstractMap.toString()

Specified by:

toString in interface PrimitiveIterable

Overrides:

toString in class Object

Returns:

a string representation of this ObjectDoubleMap

See Also:

AbstractCollection.toString()

toImmutable

ImmutableObjectDoubleMap<K> toImmutable()

Returns a copy of this map that is immutable (if this map is mutable) or itself if it is already immutable.

Returns:

an immutable map that is equivalent to this one

keySet

Set<K> keySet()

Returns a set containing all the keys in this map. The set is backed by the map, so any modifications to the returned set will affect this map.

Returns:

a mutable set containing the keys in this map

values

MutableDoubleCollection values()

Returns the values in this map as a separate collection. The returned collection is backed by the map, so any changes made to the returned collection will affect the state of this map.

Returns:

the values as a collection backed by this map

keysView

LazyIterable<K> keysView()

Returns a view of the keys in this map. This iterable is backed by the map, so any modifications to the underlying map will be reflected in the keys returned by the iterable.

Returns:

a view of the keys in this map

Since:

5.0

keyValuesView

RichIterable<ObjectDoublePair<K>> keyValuesView()

Returns a view of the key/value pairs in this map. This iterable is backed by the map, so any modifications to the underlying map will be reflected in the pairs returned by the iterable.

Returns:

a view of the keys in this map

Since:

5.0
