The connector metadata is an implementation of abstract java class JDBCMetaData. This defines what connection details need to be prompted to the user for creating a connection to a third-party source. This may include parameters like usernames, tokens, hostnames, ports, account names, etc.

The JDBCMetaData class is used for building a connection wizard for a data source. The following functions need to be implemented to create a basic connection wizard: 

• public JDBCMetaData(); 
• public void initialiseParameters(); 
• public String buttonPressed(String buttonName) throws Exception; 

Helper functions that are also accessible in JDBCMetaData: 

• protected final void addParameter(Parameter p); 
• public void setParameterValue(String key, Object value); 
• public final Object getParameterValue(String key); 
• public boolean isParameterRequired(String key); 
• public boolean hasDependentParameters(String key);
