Interface IDependentQuerySchemaProvider

  • public interface IDependentQuerySchemaProvider
    The service allows to load dependent QuerySchema model from source text feature of some object and can hold model mapped to parent object and feature. This prevents to load dependent model multiple times for each purpose of callers.

    As examples, StringLiteral in module contains feature "lines" with text of Query schema which can be parsed by Xtext in separate resource. Also, DCS contains DataSet with query text, as well some other object contains expression text feature that loads into Expression Language object.



    WARNING!
    • This dependent model should be use as read-only model, otherwise the link to parent will be removed and dependent resource will be unloaded.
    • If source text feature or source object has changed the link to dependent model will be removed and dependent resource will be unloaded.
