B.15. Language Manipulation

In Translators that support a richer set of capabilities, there is often a need to manipulate or create language interfaces with a similar syntax to those being translated to. This is often the case when translating to a language comparable to SQL. Some utilities are provided for this purpose.

Similar to the TypeFacility, you can call getLanguageFactory() method on the ExecutionFactory to get a reference to the LanguageFactory instance for your translator. This interface is a factory that can be used to create new instances of all the concrete language interface objects.

Some helpful utilities for working with Condition objects are provided in the LanguageUtil class. This class has methods to combine Condition with AND or to break a Condition apart based on AND operators. These utilities are helpful for breaking apart a criteria into individual filters that your translator can implement.
