This class is a Singleton that provides access to datadictionary objects. if a datadictionary has not yet been cached, it is created in the conventional manner. A client gets access to the single instance through the static getInstance() method and can then grap datadictionary objects

Method Index

o EmptyCache()
o getFieldMetaData(String, Integer)
returns a reference to fieldmetadata for a given field (given as an int)
o getInstance()
Returns the single instance, creating one if it's the first time this method is called.
o getResultsSet(String, String, Integer)
returns a reference to a cached resultsset (assuming it is cached).
o getTableMetaData(String, Integer)
returns a reference to tablemetadata for a given table (given as an int)
o getTableMetaData(String, String)
returns a reference to tablemetadata for a given table (given as a string)
o updateResultsSets(String, String, Integer)

Methods

o getInstance 
 public static synchronized DataCache getInstance()
Returns the single instance, creating one if it's the first time this method is called.

Returns:
DataCache - The single instance.
o getTableMetaData 
 public TableMetaData getTableMetaData(String db,
                                       String tableName) throws Exception
returns a reference to tablemetadata for a given table (given as a string)

o getTableMetaData 
 public TableMetaData getTableMetaData(String db,
                                       Integer tableNumber) throws Exception
returns a reference to tablemetadata for a given table (given as an int)

o getFieldMetaData 
 public FieldMetaData getFieldMetaData(String db,
                                       Integer fieldNumber) throws Exception
returns a reference to fieldmetadata for a given field (given as an int)

o getResultsSet 
 public ResultsSet getResultsSet(String db,
                                 String tn,
                                 Integer fn) throws Exception
returns a reference to a cached resultsset (assuming it is cached). if it isn't, then it just does the sql lookup itself. This is used for caching of automatic lookup fields

o updateResultsSets 
 public ResultsSet updateResultsSets(String db,
                                     String tn,
                                     Integer fn) throws Exception
