public interface UserSchemaComponent
extends SchemaComponent, SerializableSchemaComponent

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 Detail

fixup

boolean fixup(SchemaCompiler compiler)
              throws SchemaException

Check references from this component to other components

Parameters:

compiler -

Returns:

true if all is well, false if errors found

Throws:

SchemaException

lookForCycles

void lookForCycles(Stack references,
                   SchemaCompiler compiler)
                   throws SchemaException,
                          UnresolvedReferenceException

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 -

Throws:

SchemaException

UnresolvedReferenceException

validate

boolean validate(SchemaCompiler compiler)
                 throws SchemaException,
                        ValidationException

Checks the validity of this Schema component.

Parameters:

compiler -

Returns:

true when this Schema definition is valid, otherwise false.

Throws:

SchemaException - if the ErrorListener decides that an error is fatal.
