Detailed Description

A ConverterCacheMap views an underlying CacheMap through a set of key and value Converters.

Public Types
typedef spec::Handle	Handle
	ConverterCacheMap Handle definition.
typedef spec::View	View
	ConverterCacheMap View definition.
typedef spec::Holder	Holder
	ConverterCacheMap Holder definition.
Public Member Functions
virtual Map::View	getAll (Collection::View vKeys) const
virtual Object::Holder	put (Object::View vKey, Object::Holder ohValue, int64_t cMillis)
	Associates the specified value with the specified key in this cache. If the cache previously contained a mapping for this key, the old value is replaced. This variation of the put(Object::View, Object::View) method allows the caller to specify an expiry (or "time to live") for the cache entry. Parameters: vKey  key with which the specified value is to be associated ohValue  value to be associated with the specified key cMillis  the number of milliseconds until the cache entry will expire, also referred to as the entry's "time to live"; pass expiry_default to use the cache's default time-to-live setting; pass expiry_never to indicate that the cache entry should never expire; this milliseconds value is not a date/time value Returns: previous value associated with specified key, or empty handle if there was no mapping for key. An empty handle return can also indicate that the map previously associated NULL with the specified key, if the implementation supports NULL values Exceptions: coherence::lang::UnsupportedOperationException  if the requested expiry is a positive value and the implementation does not support expiry of cache entries
virtual void	putAll (Map::View vMap)
	Copy all of the mappings from the specified map to this map. The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is unspecified if the specified map is modified while the operation is in progress. Parameters: vMap  mappings to be stored in this map. Exceptions: coherence::lang::UnsupportedOperationException  if the put() operation is not supported by this map.
virtual CacheMap::View	getCacheMap () const
	Return the underlying CacheMap.
virtual CacheMap::Handle	getCacheMap ()
	Return the underlying CacheMap.
Protected Member Functions
	ConverterCacheMap (CacheMap::Handle hMapDelegate, EntryConverter::View vConvUp, EntryConverter::View vConvDown)
	Create a ConverterCacheMap which delegates to the specified CacheMap.
	ConverterCacheMap (CacheMap::View vMapDelegate, EntryConverter::View vConvUp, EntryConverter::View vConvDown)
	Create a ConverterCacheMap which delegates to the specified CacheMap.
