Parameters:
  params - Set of parameters needed for a postgis data store. true if dbtype equals postgis, and contains keysfor host, user, passwd, and database.



createDataStore
public DataStore createDataStore(Map params) throws IOException(Code)
Construct a postgis data store using the params.
Parameters:
  params - The full set of information needed to construct a livedata source. Should have dbtype equal to postgis, as well ashost, user, passwd, database, and table. The created DataSource, this may be null if the requiredresource was not found or if insufficent parameters were given.Note that canProcess() should have returned false if theproblem is to do with insuficent parameters.
throws:
