DAOMedge Files

NOTE:

DAOMedge targets Java 17 and doesn't, strictly speaking, conform to the DAO pattern. It was developed over many years and simply works well as it is.

For convenience the daomedgegen uses the latest daomedge.jar, but without the version number and date. This is useful to keep the projects together. You just really need the generator (daomedgegen-10.9.4-31082025.zip when it is released) as that has daomedgegen.jar, daomedge.jar (in lib/), the reservedwordsmap.properties (for syntax highlighting and reserve word avoidance), documentation, and a slightly less cheesey icon than earlier.

The actual daomedge.jar has a version number in the file name but you can use either one.

I've attempted to ensure the documentation is extensive and up to date. You can grab either the source (daomedge.odt) or the compiled version (daomedge.pdf)
They are also in the source and compiled zips respectively.

Known Issues
There is a weird issue when adding the first interface, sometimes it works, other times it fails and doesn't show up even though it is there (if yuou attempt to add the interface again it tells you that it is already there) I think it is a race condition, but am not sure. If you attempt to add another interface it fails with an index out of bounds exception. To get around this simply exit and restart.

Bash script to run the generator:

  #!/bin/bash  
  cd /folder/daomedge/daomedgegen/  
  java -Xmx2g -jar daomedgegen.jar

Bash script to run the generator command line interface:

  #!/bin/bash  
  cd /folder/daomedge/daomedgegen/  
  java -Xmx2g -jar daomedgegen.jar my_database

Or even:

  #!/bin/bash  
  cd /folder/daomedge/daomedgegen/  
  java -Xmx2g -jar daomedgegen.jar $*

Sample Code

---

Simplest:
List<Customer> customers = dao.select(Customer.class);

Pattern Matching:
Customer c = new Customer();
c.setSurname("Smith");
List<Customer> customers = dao.select(c);

Sort and Filter:
daotable table = dao.getTable(Customer.class);
daoproperty property1 = dao.getProperty(Customer.class, Customer.SURNAME);
daoproperty property2 = dao.getProperty(Customer.class, Customer.GIVENS);
OrderBy orderBy2 = new OrderBy(property2);
SelectColumn column1 = new SelectColumn(property1);
SelectColumn column2 = new SelectColumn(property2);
Filter filter = new PropertyFilter(table, property1, "Smith");
List<Customer> customers = dao.select(table, new SelectColumn[]{column1, column2}, filter, new OrderBy[]{orderBy2});

NotSQL
The Script
set classbase my.business;

{Query1}
get database.Customer.*
filter (database.Customer.surname = Smith | database.Customer.surname = 'Jones') & database.Customer.givens = 'John'
sort home.Person.dateOfBirth >;

{Query2}
sort home.Person.dateOfBirth >;
filter (database.Customer.surname not in [Smith, Jones) & database.Customer.givens = 'John'
get database.Customer.*

The Code For NotSQL
SimpleNotSQL notsql = new SimpleNotSQL(dao, notSQLScriptFromAbove);
List<Customer> customers = notsql.selectNotSQL("Query1");
customers = notsql.selectNotSQL("Query2");
// OR
customers = notsql.selectNotSQL(0);
customers = notsql.selectNotSQL(1);
