Field Detail

namespaceUri

private final java.lang.String namespaceUri

Namespace URI of this datatype. Local name is stored in the name field of ReferenceExp.

dt

private XSDatatype dt

Datatype object wrapped by this expression. This field can be null if the datatype object is not available at this moment (say, because of the forward reference). In this case, ownerState and renderer fields are available.

pool

private ExpressionPool pool

ExpressionPool that can be used if necessary.

ownerState

private transient State ownerState

State object that creates this late-binding object. The source location of this state is used for error message.

renderer

private transient XSDatatypeExp.Renderer renderer

Once the parsing is completed, this function object should be able to render the actual datatype object.

Constructor Detail

XSDatatypeExp

public XSDatatypeExp(XSDatatype dt,
                     ExpressionPool _pool)

Creates this object from existing XSDatatype.

XSDatatypeExp

public XSDatatypeExp(java.lang.String nsUri,
                     java.lang.String typeName,
                     GrammarReader reader,
                     XSDatatypeExp.Renderer _renderer)

Creates lazily created datatype.

XSDatatypeExp

private XSDatatypeExp(java.lang.String nsUri,
                      java.lang.String localName)

Used only for cloning

Method Detail

createIncubator

public XSTypeIncubator createIncubator()

Creates an incubator so that the caller can add more facets and derive a new type.

getCreatedType

public XSDatatype getCreatedType()

Gets a encapsulated datatype object This method can be called only after all the datatypes are created.

Some of the datatypes are lazily during the back-patching phase.

getType

public XSDatatype getType(XSDatatypeExp.RenderingContext context)

Gets the type definition. This method renders the datatype object if it's not rendered yet. Internal use only.

patch

public void patch()

Renders the type (GrammarReader.BackPatch implementation).

Specified by:

patch in interface GrammarReader.BackPatch

getOwnerState

public State getOwnerState()

Description copied from interface: GrammarReader.BackPatch

gets State object who has submitted this patch job.

Specified by:

getOwnerState in interface GrammarReader.BackPatch

isLateBind

public final boolean isLateBind()

getClone

public XSDatatypeExp getClone()

Gets a clone of this object.

redefine

public void redefine(XSDatatypeExp rhs)

Updates this object by copying the state from rhs

createFinalizedType

public XSDatatypeExp createFinalizedType(int finalValue,
                                         GrammarReader reader)

Derives a new type by setting final values.

makeList

public static XSDatatypeExp makeList(java.lang.String nsUri,
                                     java.lang.String typeName,
                                     XSDatatypeExp itemType,
                                     GrammarReader reader)
                              throws org.relaxng.datatype.DatatypeException

Derives a new type by list.

Throws:

org.relaxng.datatype.DatatypeException

makeUnion

public static XSDatatypeExp makeUnion(java.lang.String typeNameUri,
                                      java.lang.String typeName,
                                      java.util.Collection members,
                                      GrammarReader reader)
                               throws org.relaxng.datatype.DatatypeException
