Constructor Details

SchemaModelLoader

public SchemaModelLoader(Configuration config)

Create a schema model loader

Parameters:

config - the Saxon configuration. This must be a schema-aware configuration. This SchemaModelLoader creates a PreparedSchema but does not directly load it into the Configuration cache; that is the job of the caller.

Throws:

IllegalArgumentException - if the configuration is not schema-aware

Method Details

load

public PreparedSchema load(Source source)
                    throws XPathException

Load a schema from a serialized component model

Parameters:

source - the XML source of the serialized component model

Returns:

the corresponding PreparedSchema containing the deserialized schema components

Throws:

XPathException - if an error occurs

startElement

public void startElement(NodeName elemName,
 SchemaType type,
 AttributeMap attributes,
 NamespaceMap namespaces,
 Location location,
 int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

characters

public void characters(UnicodeString chars,
 Location locationId,
 int properties)
                throws XPathException

Character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

locationId - provides information such as line number and system ID.

properties - Bit significant value. The following bits are defined:

DISABLE_ESCAPING

Disable escaping for this text node

USE_CDATA

Output as a CDATA section

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

End of element

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException - if an error occurs

parseFinalOrBlock

public static int parseFinalOrBlock(String attrName,
 String finalValue,
 int allowed)
                             throws SchemaException

Parse a list of blocked or final derivations. Used to process the block, final, blockDefault, and finalDefault attributes.

Parameters:

attrName - the attribute name (block or final)

finalValue - A list of values to be parsed, as a string, for example "extension restriction"

allowed - The permitted values, as a bit-significant integer. For example the value (DERIVE_BY_EXTENSION | DERIVE_BY_RESTRICTION) allows the values "extension" and "restriction" to appear.

Returns:

The final/blocked values, as a bit-significant integer

Throws:

SchemaException - if a failure occurs
