All Implemented Interfaces:

com.gs.collections.api.InternalIterable<T>, com.gs.collections.api.RichIterable<T>, com.gs.collections.api.stack.MutableStack<T>, com.gs.collections.api.stack.StackIterable<T>, java.io.Externalizable, java.io.Serializable, java.lang.Iterable<T>

public class ArrayStack<T>
extends java.lang.Object
implements com.gs.collections.api.stack.MutableStack<T>, java.io.Externalizable

ArrayStack is a MutableStack which contains a FastList of data. ArrayStack iterates from top to bottom (LIFO order). It behaves like FastList in terms of runtime complexity. The method push() is amortized constant time like FastList.add(). The backing data structure grows and shrinks by 50% at a time, and size is constant. ArrayStack does not extend Vector, as does the Java Stack, which was one of the reasons to create this data structure.

flatCollect

public <V> ArrayStack<V> flatCollect(com.gs.collections.api.block.function.Function<? super T,? extends java.lang.Iterable<V>> function)

Description copied from interface: com.gs.collections.api.RichIterable

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 = new Function<Person, List<Address>>()
 {
     public List<Address> valueOf(Person person)
     {
         return person.getAddresses();
     }
 };
 MutableList<Person> people = ...;
 

Using collect returns a collection of collections of addresses.

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

Using flatCollect returns a single flattened list of addresses.

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