Constructor Detail

SchemaNodeFactory

public SchemaNodeFactory(SchemaCompiler compiler,
                         PipelineConfiguration pipe,
                         SchemaElement referrer)

Create a SchemaNodeFactory, used for building the tree representation of a schema document

Parameters:

compiler - used for error reporting

pipe - the PipelineConfiguration

referrer - the element, typically an xs:include, xs:import, or xs:redefine, that caused this schema document to be built

Method Detail

getPipelineConfiguration

public PipelineConfiguration getPipelineConfiguration()

Get the pipeline configuration

Returns:

the pipeline configuration

getSchemaCompiler

public SchemaCompiler getSchemaCompiler()

Get the SchemaCompiler associated with this node factory

Returns:

the SchemaCompiler associated with this node factory

makeElementNode

public ElementImpl makeElementNode(NodeInfo parent,
                                   NodeName elemName,
                                   SchemaType elemType,
                                   boolean isNilled,
                                   AttributeCollectionImpl attlist,
                                   NamespaceBinding[] namespaces,
                                   int namespacesUsed,
                                   PipelineConfiguration pipe,
                                   int locationId,
                                   int sequence)

Create an Element node.

Specified by:

makeElementNode in interface NodeFactory

Parameters:

parent - The parent element

elemName - The element name

elemType - The type annotation of the element

isNilled - true if the element is to be marked as nilled

attlist - The attribute collection, excluding any namespace attributes

namespaces - List of new namespace declarations for this element, as a sequence of namespace codes representing pairs of strings: (prefix1, uri1), (prefix2, uri2)...

namespacesUsed - the number of elemnts of the namespaces array actually used

pipe - The pipeline configuration (provides access to the error listener and the location provider)

locationId - Indicates the source document and line number containing the node

sequence - Sequence number to be assigned to represent document order.

registerId

public SchemaException registerId(String id,
                                  SchemaElement element)

Register an ID value found on an element in the schema document

Parameters:

id - the ID value

element - the element on which the ID value appears

Returns:

a SchemaException if the ID value is invalid or non-unique: note this is returned, not thrown.
