SchemaModelLoader
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
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 interfaceReceiver
- Overrides:
startElement
in classProxyReceiver
- Parameters:
elemName
- the name of the element.type
- the type annotation of the element.attributes
- the attributes of this elementnamespaces
- the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elementslocation
- an object providing information about the module, line, and column where the node originatedproperties
- bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in classReceiverOption
- Throws:
XPathException
- if an error occurs
-
characters
public void characters(UnicodeString chars, Location locationId, int properties) throws XPathException Character data- Specified by:
characters
in interfaceReceiver
- Overrides:
characters
in classProxyReceiver
- Parameters:
chars
- The characterslocationId
- 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
End of element- Specified by:
endElement
in interfaceReceiver
- Overrides:
endElement
in classProxyReceiver
- 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
