Field Detail

nameCode

protected int nameCode

The name of the SchemaComponent referenced

target

protected SchemaComponent target

The corresponding SchemaComponent. This is null until the reference has been resolved.

symbolSpace

protected int symbolSpace

The symbol space representing the kind of schema component that is referenced

Constructor Detail

SimpleComponentReference

protected SimpleComponentReference()

Default constructor for use by subclasses

SimpleComponentReference

public SimpleComponentReference(int symbolSpace,
                        int fingerprint,
                        EnterpriseConfiguration config)

Creates a new SimpleComponentReference definition

Parameters:

symbolSpace - the symbol space for the component reference, for example elements, attributes, or types

fingerprint - the name pool fingerprint of the component name

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

Returns:

true if the reference has been resolved to a schema component

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

Returns:

the integer fingerprint of the component name

getNameCode

public int getNameCode()

getSymbolSpace

public int getSymbolSpace()

Get the symbol space of the target of this reference

Specified by:

getSymbolSpace in interface ComponentReference

Returns:

an integer code identifying the symbol space

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

Parameters:

target - the component that this reference points to

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.
