Class ResizingObjectArray

java.lang.Object

net.automatalib.commons.util.array.ResizingObjectArray

public final class ResizingObjectArray
extends Object

Class that provides a resizable Object array storage. Unlike ResizingArrayStorage, the array provided by this class is always of type Object[]. This results in a higher efficiency, since there is no need for reflection when creating new arrays.
