Method Summary public  String dumpCacheConfig()      Retrieves the current request parsing cache configuration. public  String dumpCacheEntries(int beginIndex, int max)      public  String dumpCurrentlyParsedEntries()      public  int getGranularity()      Returns the granularity value. public  int getNumberOfCacheEntries()      public  void getParsingFromCache(AbstractRequest request)      If the same SQL query is found in the cache, the parsing is cloned into the given request. public  void getParsingFromCacheAndParseIfMissing(AbstractRequest request)      Method getParsingFromCacheAndParseIfMissing. public  RequestManager getRequestManager()      Returns the requestManager value. public  String getXml()      public  boolean isBackgroundParsing()      Returns the backgroundParsing. public  boolean isCaseSensitiveParsing()      Returns the caseSensitiveParsin. public  void setBackgroundParsing(boolean backgroundParsing)      Sets the background parsing. public  void setCaseSensitiveParsing(boolean isCaseSensitiveParsing)      public  void setGranularity(int granularity)      Sets the granularity value. public  void setRequestManager(RequestManager requestManager)      Sets the requestManager value. Constructor Detail ParsingCache public ParsingCache(int size, boolean backgroundParsing)(Code) Constructor for ParsingCache. Parameters:   size - maximum cache size in nb of entries Parameters:   backgroundParsing - true if the parsing should be done in backgroundby a ParserThread Method Detail dumpCacheConfig public String dumpCacheConfig()(Code) Retrieves the current request parsing cache configuration. The returned string contains: granularity maximum number of entries background parsing flag case sensitivity a String containing the configuration of the cache dumpCacheEntries public String dumpCacheEntries(int beginIndex, int max)(Code) Prints entries of the cache, from beginIndex to (beginIndex + max) or to the last entry if beginIndex+max is out of bounds Parameters:   beginIndex - entry from which to start dump Parameters:   max - maximum number of entries to dump a string containing the cache entries (request unique key + shortdescription string) from beginIndex to the last entry or tobeginIndex+max. dumpCurrentlyParsedEntries public String dumpCurrentlyParsedEntries()(Code) Dumps requests that are currently beeing parsed a String containing the entries (request unique key + shortdescription string) currently beeing parsed getGranularity public int getGranularity()(Code) Returns the granularity value. Returns the granularity. getNumberOfCacheEntries public int getNumberOfCacheEntries()(Code) Retrieves the number of entries currently contained in the cache number of cache entries getParsingFromCache public void getParsingFromCache(AbstractRequest request)(Code) If the same SQL query is found in the cache, the parsing is cloned into the given request. If backgroundParsing is set to true, then a ParserThread starts parsing the request in background else nothing is done on a cache miss. Parameters:   request - the request you look for getParsingFromCacheAndParseIfMissing public void getParsingFromCacheAndParseIfMissing(AbstractRequest request) throws SQLException(Code) Method getParsingFromCacheAndParseIfMissing. Parameters:   request - the request we look for exception:   SQLException - if an error occurs getRequestManager public RequestManager getRequestManager()(Code) Returns the requestManager value. Returns the requestManager. getXml public String getXml()(Code) Get xml information about this ParsingCache String in xml formatted text isBackgroundParsing public boolean isBackgroundParsing()(Code) Returns the backgroundParsing. boolean isCaseSensitiveParsing public boolean isCaseSensitiveParsing()(Code) Returns the caseSensitiveParsin. boolean setBackgroundParsing public void setBackgroundParsing(boolean backgroundParsing)(Code) Sets the background parsing. If true the request are parsed in background by a separate thread that is created for this purpose. Parameters:   backgroundParsing - The backgroundParsing to set setCaseSensitiveParsing public void setCaseSensitiveParsing(boolean isCaseSensitiveParsing)(Code) Sets the parsing case sensitivity Parameters:   isCaseSensitiveParsing - true if parsing is case sensitive setGranularity public void setGranularity(int granularity)(Code) Sets the granularity value. Parameters:   granularity - The granularity to set. setRequestManager public void setRequestManager(RequestManager requestManager)(Code) Sets the requestManager value. Parameters:   requestManager - The requestManager to set.
