Package org.talend.sdk.component.api.record

Class OrderedMap<T>

java.lang.Object

org.talend.sdk.component.api.record.OrderedMap<T>

Type Parameters:

T - : type of element.

public class OrderedMap<T>
extends Object

On TCK Record, we have to control order of elements with keeping efficient access. LinkedHashMap has efficient access, but order of element is only the order of insertions. List (ArrayList, LinkedList) allow to fine control order but have inefficent access. This class aims to control element order with keeping efficient access.
