Constructor Detail

SimpleComponentReference

public SimpleComponentReference(int symbolSpace,
                                int fingerprint,
                                SchemaAwareConfiguration config)
Creates a new SimpleComponentReference definition

Parameters:
config - the configuration to which this component belongs
Method Detail

isResolved

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

Specified by:
isResolved in interface ComponentReference

setNameCode

public void setNameCode(int nameCode)

getFingerprint

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

Specified by:
getFingerprint in interface ComponentReference

getNameCode

public int getNameCode()

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 schema component that this 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.

setTarget

public void setTarget(SchemaComponent target)
Set the target component


tryToResolve

public void tryToResolve(SchemaCompiler compiler)
Attempt to resolve this reference using the components 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.
