public boolean isEmptiable()
                    throws UnresolvedReferenceException

Determine if empty content is allowed

Specified by:

isEmptiable in class ModelGroup

true if the particle is pointless (which effectively means it can't match anything)

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException

Checks the validity of this Compositor definition.

Specified by:

validate in interface UserSchemaComponent

Overrides:

validate in class ModelGroup

Returns:

true when this Schema definition is valid, otherwise false.

Throws:

SchemaException - when the error listener decides an error is fatal
