メソッド

CacheBehavior org.objectweb.cjdbc.controller.cache.result.ResultCacheFactory.getCacheBehaviorInstance (  String  behaviorString, Hashtable  options )  [static]

Get an instance of a cache behavior for this cache 引数: behaviorString  representation of this cache behavior, xml tag options  for different cache rules 戻り値: an instance of a cache behavior ResultCacheFactory.java の 85 行で定義されています。 { if (behaviorString.equalsIgnoreCase(DatabasesXmlTags.ELT_NoCaching)) return new NoCaching(); if (behaviorString.equals(DatabasesXmlTags.ELT_EagerCaching)) return new EagerCaching(); if (behaviorString.equals(DatabasesXmlTags.ELT_RelaxedCaching)) { // Timeout is in seconds: *1000 long timeout = 1000 * Long.parseLong((String) options .get(DatabasesXmlTags.ATT_timeout)); boolean keepIfNotDirty = new Boolean((String) options .get(DatabasesXmlTags.ATT_keepIfNotDirty)).booleanValue(); return new RelaxedCaching(keepIfNotDirty, timeout); } else return null; }

AbstractResultCache org.objectweb.cjdbc.controller.cache.result.ResultCacheFactory.getCacheInstance (  int  granularityValue, int  maxEntries, int  pendingTimeout )  throws InstantiationException [static]

Get an instance of the current cache implementation 引数: granularityValue  of the parsing maxEntries  to the cache pendingTimeout  before pending query timeout 戻り値: ResultCache implementation of the AbstractResultCache 例外: InstantiationException  if parsing granularity is not valid ResultCacheFactory.java の 52 行で定義されています。 { AbstractResultCache currentRequestCache = null; switch (granularityValue) { case CachingGranularities.TABLE : currentRequestCache = new ResultCacheTable(maxEntries, pendingTimeout); break; case CachingGranularities.DATABASE : currentRequestCache = new ResultCacheDatabase(maxEntries, pendingTimeout); break; case CachingGranularities.COLUMN : currentRequestCache = new ResultCacheColumn(maxEntries, pendingTimeout); break; case CachingGranularities.COLUMN_UNIQUE : currentRequestCache = new ResultCacheColumnUnique(maxEntries, pendingTimeout); break; default : throw new InstantiationException("Invalid Granularity Value"); } return currentRequestCache; }
