Class DictionaryAttributeMap

java.lang.Object
  |
  +--oracle.cabo.ui.collection.DictionaryAttributeMap

All Implemented Interfaces:

AttributeMap

public final class DictionaryAttributeMap

extends java.lang.Object

implements AttributeMap

AttributeMap implementation that delegates storage of the AttibuteMap to a Dictionary. Although this implementation is the fastest when large numbers of unindexed AttributeKey values are stored in the AttributeMap, for most uses FlaggedAttributeMap has similar or better performance at a much smaller memory cost, while IndexedAttributeMap is faster with a similar cost.
