boolean	containsKey(double key) Returns whether or not the key is present in the map.
boolean	equals(Object o) Follows the same general contract as Map.equals(Object).
IntDoubleMap	flipUniqueValues() Return the IntDoubleMap that is obtained by flipping the direction of this map and making the associations from value to key.
void	forEachKey(DoubleProcedure procedure) Iterates through each key in the map, invoking the procedure for each.
void	forEachKeyValue(DoubleIntProcedure procedure) Iterates through each key/value pair in the map, invoking the procedure for each.

MutableDoubleSet	keySet() Returns a set containing all the keys in this map.
LazyDoubleIterable	keysView() Returns a view of the keys in this map.
RichIterable<DoubleIntPair>	keyValuesView() Returns a view of the key/value pairs in this map.
DoubleIntMap	reject(DoubleIntPredicate predicate) Return a copy of this map containing only the key/value pairs that do not match the predicate.
DoubleIntMap	select(DoubleIntPredicate predicate) Return a copy of this map containing only the key/value pairs that match the predicate.
ImmutableDoubleIntMap	toImmutable() Returns a copy of this map that is immutable (if this map is mutable) or itself if it is already immutable.
String	toString() Follows the same general contract as AbstractMap.toString()

Method Detail

get

int get(double 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

getIfAbsent

int getIfAbsent(double key,
                int 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.

getOrThrow

int getOrThrow(double 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

containsKey

boolean containsKey(double 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

forEachKey

void forEachKey(DoubleProcedure 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(DoubleIntProcedure 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

keysView

LazyDoubleIterable 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<DoubleIntPair> 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

flipUniqueValues

IntDoubleMap flipUniqueValues()

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

Throws:

IllegalStateException - if the IntDoubleMap contains duplicate values.

Since:

9.0

select

DoubleIntMap select(DoubleIntPredicate 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

DoubleIntMap reject(DoubleIntPredicate 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

equals

boolean equals(Object o)

Follows the same general contract as Map.equals(Object).

Overrides:

equals in class Object

hashCode

int hashCode()

Follows the same general contract as Map.hashCode().

Overrides:

hashCode in class Object

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 DoubleIntMap

See Also:

AbstractCollection.toString()

toImmutable

ImmutableDoubleIntMap 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

MutableDoubleSet 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
