Backend Coding Standards

This page is a collection of coding standards in the ovirt engine backend. Not all of these standards are properly maintained, they are more like ‘guidelines’

Java code conventions

Java code style conventions and best practices should be applied in the project.

RowMapper singletons

RowMappers should have a single instance e.g.

  private final static class FooRowMapper implements ParameterizedRowMapper`<Foo>` {
    public final static FooRowMapper instance = new FooRowMapper();
    public Foo mapRow(ResultSet rs, int rowNum) {
      //and so on...
    }
  }

So you do not have to instantiate the rowmapper all the time.
