Class MetaDataResolver

java.lang.Object
  com.googlecode.jdbw.metadata.MetaDataResolver

public class MetaDataResolver
extends Object

The MetaDataResolver is used to extract meta data from the database server. It is mostly a wrapper around the DatabaseMetaData class, but can also be overridden to provide a custom behavior. This can be useful, for example, if the database server doesn't support concepts such as Catalog or Schema.
