All Implemented Interfaces:

AttributeMap

Direct Known Subclasses:

FlaggedAttributeMap, IndexedAttributeMap

public class ArrayAttributeMap

extends java.lang.Object

implements AttributeMap

AttributeMap implementation that stores AttributeKey value pairs in an array and locates the desired AttributeKey by making a linear scan.

Although extremely memory efficient and fast for the number of attributes stored on most UINodes ( < 15), FlaggedAttributeMap is a better general purpose AttributeMap implementation for use as UINode storage.
