159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

26 | /**
27 | * Database configuration file helper class that is used to write a configuration file into the raw resource
28 | * sub-directory to speed up DAO creation.
29 | *
30 | *
31 | * With help from the user list and especially Ian Dees, we discovered that calls to annotation methods in Android are
32 | * _very_ expensive because Method.equals() was doing a huge toString(). This was causing folks to see 2-3 seconds
33 | * startup time when configuring 10-15 DAOs because of 1000s of calls to @DatabaseField methods. See this Android bug report.
35 | *
36 | *
37 | *
38 | * I added this utility class which writes a configuration file into the raw resource "res/raw" directory inside of your
39 | * project containing the table and field names and associated details. This file can then be loaded into the
40 | * {@link DaoManager} with the help of the
41 | * {@link OrmLiteSqliteOpenHelper#OrmLiteSqliteOpenHelper(android.content.Context, String, android.database.sqlite.SQLiteDatabase.CursorFactory, int, int)}
42 | * constructor. This means that you can configure your classes _without_ any runtime calls to annotations. It seems
43 | * significantly faster.
44 | *
45 | *
46 | *
47 | * WARNING: Although this is fast, the big problem is that you have to remember to regenerate the config file
48 | * whenever you edit one of your database classes. There is no way that I know of to do this automagically.
