Question

I use ormlite with android and I’ve some poco class.

Example :

public class TableName {
  @DatabaseField(id = true)
  public Integer id;

  @DatabaseField
  public String prop;
}

I want to create sometimes

QueryBuilder<TableName, Integer> qb = dao.queryBuilder();
qb.where().eq("prop", "value");

I’d like to validate the “prop” string without using constants in my poco class (like PROPNAME). Do you know a efficiant way to do this ? (without heavy load stuff like reflexion).

I’d really like code validation.

Regards

The ORMLite documentation organizes it this way, to avoid string literals everywhere:

public class TableName {
  public static final String FIELD_ID = "id";
  public static final String FIELD_PROP = "prop";

  @DatabaseField(id = true)
  public Integer id;

  @DatabaseField
  public String prop;
}

QueryBuilder<TableName, Integer> qb = dao.queryBuilder();
qb.where().eq(TableName.FIELD_PROP, "value");

Internally ORMLite uses reflection when you pass this string in, so it is unavoidable when using this library.
