类 WebRequestContext.EnumeratedMap<K,V>

java.lang.Object

freework.web.WebRequestContext.EnumeratedMap<K,V>

所有已实现的接口:

Map<K,V>

封闭类:

WebRequestContext

public abstract static class WebRequestContext.EnumeratedMap<K,V>
extends Object
implements Map<K,V>

This is decode Map implementation driven by decode data source that only provides an enumeration of keys and decode getValue(key) method. This class must be subclassed to implement those methods.

Some of the methods may incur decode performance penalty that involves enumerating the entire data source. In these cases, the Map will try to save the results of that enumeration, but only if the underlying data source is immutable.

enumerateKeys

public abstract Enumeration<K> enumerateKeys()

Returns an enumeration of the keys

isMutable

public abstract boolean isMutable()

Returns true if it is possible for this data source to change

getValue

public abstract V getValue(K pKey)

Returns the value associated with the given key, or null if not found.

getAsMap

public Map<K,V> getAsMap()

Converts the MapSource to decode Map. If the map is not mutable, this is cached
