All Implemented Interfaces:
DialectResolver

A DialectResolver implementation which coordinates resolution by delegating to its registered sub-resolvers. Sub-resolvers may be registered by calling either #addResolver or #addResolverAtFirst .

Method from org.hibernate.dialect.resolver.DialectResolverSet Detail:
public void addResolver(DialectResolver resolver) { resolvers.add( resolver ); } Add a resolver at the end of the underlying resolver list. The resolver added by this method is at lower priority than any other existing resolvers.
public void addResolverAtFirst(DialectResolver resolver) { resolvers.add( 0, resolver ); } Add a resolver at the beginning of the underlying resolver list. The resolver added by this method is at higher priority than any other existing resolvers.
public Dialect resolveDialect(DatabaseMetaData metaData) { Iterator i = resolvers.iterator(); while ( i.hasNext() ) { final DialectResolver resolver = ( DialectResolver ) i.next(); try { Dialect dialect = resolver.resolveDialect( metaData ); if ( dialect != null ) { return dialect; } } catch ( JDBCConnectionException e ) { throw e; } catch ( Throwable t ) { log.info( "sub-resolver threw unexpected exception, continuing to next : " + t.getMessage() ); } } return null; } {@inheritDoc}

Method from org.hibernate.dialect.resolver.DialectResolverSet Detail:

 public  void addResolver(DialectResolver resolver) {
		resolvers.add( resolver );
}

Add a resolver at the end of the underlying resolver list. The resolver added by this method is at lower priority than any other existing resolvers.

 public  void addResolverAtFirst(DialectResolver resolver) {
		resolvers.add( 0, resolver );
}

Add a resolver at the beginning of the underlying resolver list. The resolver added by this method is at higher priority than any other existing resolvers.
