public interface UserSchemaComponent extends SchemaComponent
A SchemaComponent is an object in a schema. While the schema is being built, a list of such objects is maintained, and on completion, the fixup method is called to resolve forwards references. Subsequently, the validate method is called to invoke validation

  • Method Details

    • fixup

      boolean fixup(SchemaCompiler compiler) throws SchemaException
      Check references from this component to other components
      Parameters:
      compiler - the schema compiler
      Returns:
      true if all is well, false if errors found
      Throws:
      SchemaException

    • lookForCycles

      void lookForCycles(Stack<SchemaComponent> references, SchemaCompiler compiler) throws SchemaException, MissingComponentException
      This method is called to look for cycles. The object implementing this method is required (a) to raise an exception if the object itself appears in the list of references, (b) to add itself to the list of references, and (c) to call the lookForCycles method on all the objects that it references.
      Parameters:
      references - A stack of objects that contain direct or indirect references to this object, and that must therefore not be referred to from this object.
      compiler - the schema compiler
      Throws:
      SchemaException - if cycles are found
      MissingComponentException

    • validate

      boolean validate(SchemaCompiler compiler) throws SchemaException
      Checks the validity of this Schema component.
      Parameters:
      compiler - the schema compiler
      Returns:
      true when this Schema definition is valid, otherwise false.
      Throws:
      SchemaException - if the ErrorListener decides that an error is fatal.

    • elaborate

      void elaborate(SchemaCompiler compiler) throws SchemaException
      Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes. The model is assumed to be valid.
      Parameters:
      compiler - the schema compiler
      Throws:
      SchemaException
