Implements org.eclipse.collections.api.set.MutableSet.asSynchronized, org.eclipse.collections.api.collection.MutableCollection.asSynchronized.

Doc from org.eclipse.collections.api.collection.MutableCollection.asSynchronized.

Returns a synchronized wrapper backed by this collection. This is the equivalent of using Collections.synchronizedCollection(this) only with a return type that supports the full iteration protocols available on MutableCollection. The preferred way of iterating over a synchronized collection is to use the internal iteration methods which are properly synchronized internally.

 MutableCollection synchedCollection = collection.asSynchronized();
    ...
 synchedCollection.forEach(each -> ... );
 synchedCollection.select(each -> ... );
 synchedCollection.collect(each -> ... );

Redeclares org.eclipse.collections.api.set.MutableSet.clone.

Overrides java.lang.Object.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

x.clone() != x

x.clone().getClass() == x.getClass()

x.clone().equals(x)

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Implements org.eclipse.collections.api.set.MutableSet.collect, org.eclipse.collections.api.collection.MutableCollection.collect, org.eclipse.collections.api.RichIterable.collect.

Doc from org.eclipse.collections.api.RichIterable.collect.

Returns a new collection with the results of applying the specified function on each element of the source collection. This method is also commonly called transform or map.

Example using a Java 8 lambda expression:

RichIterable<String> names =
    people.collect(person -> person.getFirstName() + " " + person.getLastName());

Doc from org.eclipse.collections.api.RichIterable.collectIf.

Returns a new collection with the results of applying the specified function on each element of the source collection, but only for those elements which return true upon evaluation of the predicate. This is the optimized equivalent of calling iterable.select(predicate).collect(function).

Example using a Java 8 lambda and method reference:

RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(e -> e != null, Object::toString);

Example using Predicates factory:

RichIterable<String> strings = Lists.mutable.with(1, 2, 3).collectIf(Predicates.notNull(), Functions.getToString());

Same as collect(Function) with a Function2 and specified parameter which is passed to the block.

@Override

Overrides org.eclipse.collections.impl.AbstractRichIterable.detect.

Implements org.eclipse.collections.api.RichIterable.detect.

Doc from org.eclipse.collections.api.RichIterable.detect.

Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true. This method is commonly called find.

Example using a Java 8 lambda expression:

Person person =
    people.detect(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));

@Override

Implements org.eclipse.collections.api.RichIterable.detectOptional.

Doc from org.eclipse.collections.api.RichIterable.detectOptional.

Returns the first element of the iterable for which the predicate evaluates to true as an Optional. This method is commonly called find.

Example using a Java 8 lambda expression:

Person person =
    people.detectOptional(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));

@Override

Implements org.eclipse.collections.api.set.MutableSet.difference.

Doc from org.eclipse.collections.api.set.SetIterable.difference.

Returns the set of all members of this that are not members of subtrahendSet. The difference of [1, 2, 3] and [2, 3, 4] is [1].

Annotations

@Override

Doc from org.eclipse.collections.api.RichIterable.flatCollect.

flatCollect is a special case of 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 = ...;

RichIterable<List<Address>> addresses = people.collect(addressFunction);

RichIterable<Address> addresses = people.flatCollect(addressFunction);

Implements org.eclipse.collections.api.RichIterable.groupByUniqueKey.

Doc from org.eclipse.collections.api.RichIterable.groupByUniqueKey.

For each element of the iterable, the function is evaluated, and the results of these evaluations are collected into a new map, where the transformed value is the key. The generated keys must each be unique, or else an exception is thrown.

Implements org.eclipse.collections.api.collection.MutableCollection.injectIntoWith.

Doc from org.eclipse.collections.api.collection.MutableCollection.injectIntoWith.

Returns the final result of evaluating function using each element of the iterable, the previous evaluation result and the parameters. The injected value is used for the first parameter of the first evaluation, and the current item in the iterable is used as the second parameter. The parameter value is always used as the third parameter to the function call.

@Override

Implements org.eclipse.collections.api.set.MutableSet.intersect.

Doc from org.eclipse.collections.api.set.SetIterable.intersect.

Returns the set of all objects that are members of both this and set. The intersection of [1, 2, 3] and [2, 3, 4] is the set [2, 3]. The output will contain instances from the smaller of the two sets (this or set) based on the size. If the sizes are equal, the output will contain instances from this.

Doc from java.util.Set.retainAll.

Retains only the elements in this set that are contained in the specified collection (optional operation). In other words, removes from this set all of its elements that are not contained in the specified collection. If the specified collection is also a set, this operation effectively modifies this set so that its value is the intersection of the two sets.

Doc from org.eclipse.collections.api.set.SetIterable.symmetricDifference.

Returns the set of all objects that are a member of exactly one of this and setB (elements which are in one of the sets, but not in both). For instance, for the sets [1, 2, 3] and [2, 3, 4], the symmetric difference set is [1, 4] . It is the set difference of the union and the intersection.
