public interface ComponentReference

extends javax.xml.transform.SourceLocator

A reference to a schema component. The reference may have been resolved to a specific component, or may be as yet unresolved. Any attempt to use a reference that has not yet been resolved causes an unchecked exception.

Method Summary

int	getFingerprint() Get the fingerprint of the target of this reference
PreparedSchema	getSchema() Determine the schema containing this reference
int	getSymbolSpace() Get the symbol space of the target of this reference
SchemaComponent	getTarget() Get the schema component identified by this reference.
boolean	isResolved() Determine whether this reference has been resolved
void	tryToResolve(PreparedSchema schema) Try to resolve the reference if possible, relative to components present in a given schema.

Method Detail

getSchema

public PreparedSchema getSchema()

Determine the schema containing this reference

tryToResolve

public void tryToResolve(PreparedSchema schema)

Try to resolve the reference if possible, relative to components present in a given schema. No error occurs if the reference cannot yet be resolved.

Parameters:

schema - The schema containing the candidate target components for the reference. If null, the schema containing the reference is used.

isResolved

public boolean isResolved()

Determine whether this reference has been resolved

getTarget

public SchemaComponent getTarget()
                          throws UnresolvedReferenceException

Get the schema component identified by this reference.

Returns:

the schema component if the reference has been resolved.

Throws:

UnresolvedReferenceException - if the reference has not been resolved. Note that this is an unchecked exception.

getFingerprint

public int getFingerprint()

Get the fingerprint of the target of this reference

getSymbolSpace

public int getSymbolSpace()

Get the symbol space of the target of this reference
