Subject Generator: comparison TORQUE_3_1_BRANCH vs HEAD
Date Fri, 21 Jan 2005 17:35:54 GMT




Hi,

I have looked into the differences between the CVS branches
TORQUE_3_1_BRANCH and HEAD in the Torque generator. In short, it seems that
the HEAD branch is more advanced than the TORQUE_3_1_BRANCH, except for
Henning's correctGetters.

Improvements in TORQUE_3_1_BRANCH
Henning's correctGetters - improvement

Improvements in HEAD:
Refactoring of the model
replaced db.props files by java classes
removed support for "autoincrement" and "sequence" (is now "native")

In my opinion, we should not loose the improvements made in HEAD. It seems
to be feasible to incorporate the correctGetters in HEAD.

Changes in details:


Different version of StringUtils, version in 3_1 is newer. Main difference
seems to be name of method capitalise/capitalize

src/java:
Package torque.engine
EngineException: no change

Package torque.engine.database.model
AppData.java is removed in HEAD. This means we cannot handle more than one
database at a time. No idea whether that is needed.

Column.java:
size,torqueType,defaultValue was moved to new member Domain
columnType is not needed any more
...


ConstraintNameGenerator: adjusted to other changes
Database.java: Does not contain AppData any more, but additionally contains
a Map of Domains and a filename
getTables() returns List, not array

Domain.java: added in HEAD, holds some of the data of column.java. Holds
all data for a column data type (like, which is its sql name, size,...)
I am not content with the name of the class, is not intuitive. Call it
ColumnType ???
private String name; // unique identifier for the domain, seems to be used
in xml generation
private String description; // not heavily used except in loading from xml
private String size;  // from Column.java
private String scale; // e.g. in Oracle number (10,2);
private SchemaType torqueType; // from Column.java
private String sqlType; // how the type of the column is called in SQL.
Depends from Platform.
private String defaultValue; // from Column.java

IdMethod: Autoincrement and sequence are not supported any more
IdMethodParameter: No changes
Index.java: slight code improvements in HEAD
Inheritance.java: No changes
JavaNameGenerator: Difference in version of StringUtils
NameFactory: No changes
SchemaType: Only Exists in Head. Enumeration for all types in schema.xml,
previously constants in TypeMap.java

autoincrement and sequence support is dropped
in 3_1, the correctGetters are added

TypeMap.java: Some constants have been moved to SchemaType
Slight differences in BIT_OBJECT_TYPE
Slight differences in getTorqueType()
