What types of expressions does JUDO support?

It supports DataExpressions for value computation, ReferenceExpressions for object navigation, and LogicalExpressions for filtering data.

What are the different roles in JUDO bindings?

Bindings primarily use GETTER roles for reading derived values from entities to transfer objects and SETTER roles for writing values back.

How does this skill handle circular references?

The skill utilizes the TransferObjectTypeBindingsCollector's internal cache to identify and prevent infinite recursion during expression resolution.

What is the primary purpose of JUDO Expression Syntax?

It is used to define and resolve the logic that maps data between backend entities and transfer objects, including computed values and navigation paths.

Can I use this skill to debug 'Attribute is not mapped' errors?

Yes, it provides specific debugging workflows to inspect the TransferObjectGraph and verify that all necessary attribute bindings exist.

关于

The JUDO Expression Syntax skill provides comprehensive guidance for working with the JUDO runtime's expression architecture. It enables developers to define and manage how Transfer Objects (TOs) map to Entities using complex bindings, including derived attributes and computed filters. By offering structured patterns for Data, Reference, and Logical expressions, this skill helps ensure data integrity across the DAO layer while providing specific troubleshooting steps for common resolution errors such as missing bindings or circular references.
