Field Detail

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,
                        StructuredQName name,
                        EnterpriseConfiguration config)

Creates a new SimpleComponentReference definition

Parameters:

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

name - 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

setTargetComponentName

public void setTargetComponentName(StructuredQName name)

getTargetComponentName

public StructuredQName getTargetComponentName()

Description copied from interface: ComponentReference

Get the name of the target of this reference

Specified by:

getTargetComponentName in interface ComponentReference

Returns:

the component name of the target component

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 MissingComponentException

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:

MissingComponentException - 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.

isDangling

public boolean isDangling()

Ask whether this is known to be a dangling reference

Specified by:

isDangling in interface ComponentReference

Returns:

true if the target of this component reference is known to be absent, and if a warning has been issued to this effect
