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 Summary

Modifier and Type	Method	Description
void	elaborate(SchemaCompiler compiler)	Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes.
boolean	fixup(SchemaCompiler compiler)	Check references from this component to other components
void	lookForCycles(java.util.Stack<SchemaComponent> references, SchemaCompiler compiler)	This method is called to look for cycles.
boolean	validate(SchemaCompiler compiler)	Checks the validity of this Schema component.

Method Detail

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(java.util.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
