SchemaPrinter (IBM FHIR Server)

java.lang.Object
- com.ibm.fhir.schema.app.SchemaPrinter

```
public class SchemaPrinter
extends Object
```
The SchemaPrinter outputs the DDL into three files - schema.sql, grants.sql, stored-procedures.sql.
These files are generated using Mock java.sql objects. These mock objects follow through the code to
capture the SQL as it flows to the prospective database:
- Build a JDBCTarget with PrintConnection
- The Database Tools builds the schema retrieving a PreparedStatement, CallableStatement or Statement from the PrintConnection
- The PrintConnection passes a PrintPreparedStatement, PrintCallableStatement, PrintStatement
- As the prepareStatement, execute or executeQuery are executed, the SQL passed is put into the commands or stored procedures map.
- the results, after the full schema generation, is printed out to console or files
