Constructor Detail

TypeReference

public TypeReference(int fingerprint,
                     EnterpriseConfiguration config,
                     SourceLocator locator)
Creates a new Type reference

Parameters:
fingerprint - the Name Pool fingerprint of the name of the type being referenced
config - identifies the XML Schema in which this type reference appears. May be null if the reference is in a built-in type
locator - the SourceLocator identifying the location of the reference. May be null if the reference is in a built-in type
Method Detail

isResolved

public boolean isResolved()
Determine whether this reference has been resolved

Specified by:
isResolved in interface ComponentReference

setTarget

public void setTarget(SchemaType target)

getFingerprint

public int getFingerprint()
Description copied from interface: ComponentReference
Get the fingerprint of the target of this reference

Specified by:
getFingerprint in interface ComponentReference

getSymbolSpace

public int getSymbolSpace()
Get the symbol space of the target of this reference

Specified by:
getSymbolSpace in interface ComponentReference

getTarget

public SchemaComponent getTarget()
                          throws UnresolvedReferenceException
Returns the type that this type reference is a reference to

Specified by:
getTarget in interface ComponentReference
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.

tryToResolve

public void tryToResolve(SchemaCompiler compiler)
Attempt to resolved this reference using the groups defined in a given schema. No error results if the reference cannot be resolved.

Specified by:
tryToResolve in interface ComponentReference
Parameters:
compiler - The compiler being used to compile the referring component. This is assumed to know about the schema containing the candidate target components for the reference. If null, the schema containing the reference is used.
