MutableMapIterable
Collections.synchronizedMap(this)
only with the more feature rich return type of
MutableMapIterable
.
The preferred way of iterating over a synchronized map is to use the forEachKey(), forEachValue() and forEachKeyValue() methods which are properly synchronized internally.
MutableMap synchedMap = map.asSynchronized(); synchedMap.forEachKey(key -> ... ); synchedMap.forEachValue(value -> ... ); synchedMap.forEachKeyValue((key, value) -> ... );
If you want to iterate imperatively over the keySet(), values(), or entrySet(), you will need to protect the iteration by wrapping the code in a synchronized block on the map.

->
Range return a multimap from Range ->
Domain. We chose the name 'flip'
rather than 'invert' or 'transpose' since this method does not have the property of applying twice
returns the original.
Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

public <VV> MutableList<VV> flatCollect(Function<? super V,? extends Iterable<VV>> function)

flatCollect
is a special case of RichIterable.collect(Function)
. With collect
, when the Function
returns
a collection, the result is a collection of collections. flatCollect
outputs a single "flattened" collection
instead. This method is commonly called flatMap.
Consider the following example where we have a Person
class, and each Person
has a list of Address
objects. Take the following Function
:
Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;Using
collect
returns a collection of collections of addresses.
RichIterable<List<Address>> addresses = people.collect(addressFunction);Using
flatCollect
returns a single flattened list of addresses.
RichIterable<Address> addresses = people.flatCollect(addressFunction);
