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
