DocumentWrapper
public DocumentWrapper(nu.xom.Node root, java.lang.String baseURI, Configuration config)
Create a Saxon wrapper for a XOM root node- Parameters:
root
- The XOM root nodebaseURI
- The base URI for all the nodes in the treeconfig
- The configuration which defines the name pool used for all names in this tree
-
-
Method Detail
-
wrap
public NodeInfo wrap(nu.xom.Node node)
Wrap a node in the XOM document.- Parameters:
node
- The node to be wrapped. This must be a node in the same document (the system does not check for this).- Returns:
- the wrapping NodeInfo object
-
setConfiguration
public void setConfiguration(Configuration config)
Set the configuration, which defines the name pool used for all names in this document. This is always called after a new document has been created. The implementation must register the name pool with the document, so that it can be retrieved using getNamePool(). It must also call NamePool.allocateDocumentNumber(), and return the relevant document number when getDocumentNumber() is subsequently called.- Parameters:
config
- The configuration to be used
-
getConfiguration
public Configuration getConfiguration()
Get the configuration previously set using setConfiguration- Specified by:
getConfiguration
in interfaceNodeInfo
- Overrides:
getConfiguration
in classNodeWrapper
- Returns:
- the Configuration
-
getNamePool
public NamePool getNamePool()
Get the name pool used for the names in this document- Specified by:
getNamePool
in interfaceNodeInfo
- Overrides:
getNamePool
in classNodeWrapper
- Returns:
- the name pool in which all the names used in this document are registered
-
isTyped
public boolean isTyped()
Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED- Specified by:
isTyped
in interfaceDocumentInfo
- Returns:
- true if the document contains elements whose type is other than UNTYPED
-
getDocumentNumber
public long getDocumentNumber()
Get the unique document number for this document (the number is unique for all documents within a NamePool)- Specified by:
getDocumentNumber
in interfaceNodeInfo
- Overrides:
getDocumentNumber
in classNodeWrapper
- Returns:
- the unique number identifying this document within the name pool
-
selectID
public NodeInfo selectID(java.lang.String id, boolean getParent)
Get the element with a given ID, if any- Specified by:
selectID
in interfaceDocumentInfo
- Parameters:
id
- the required ID valuegetParent
-- Returns:
- the element with the given ID, or null if there is no such ID present (or if the parser has not notified attributes as being of type ID).
-
getUnparsedEntityNames
public java.util.Iterator<java.lang.String> getUnparsedEntityNames()
Get the list of unparsed entities defined in this document- Specified by:
getUnparsedEntityNames
in interfaceDocumentInfo
- Returns:
- an Iterator, whose items are of type String, containing the names of all unparsed entities defined in this document. If there are no unparsed entities or if the information is not available then an empty iterator is returned
-
getUnparsedEntity
public java.lang.String[] getUnparsedEntity(java.lang.String name)
Get the unparsed entity with a given name- Specified by:
getUnparsedEntity
in interfaceDocumentInfo
- Parameters:
name
- the name of the entity- Returns:
- null: XOM does not provide access to unparsed entities
-
getTypeAnnotation
public int getTypeAnnotation()
Get the type annotation of this node, if any. Returns -1 for kinds of nodes that have no annotation, and for elements annotated as untyped, and attributes annotated as untypedAtomic.- Specified by:
getTypeAnnotation
in interfaceNodeInfo
- Overrides:
getTypeAnnotation
in classNodeWrapper
- Returns:
- the type annotation of the node.
- See Also:
Type
-
getSchemaType
public SchemaType getSchemaType()
Get the type annotation of this node, if any. The type annotation is represented as SchemaType object.Types derived from a DTD are not reflected in the result of this method.
- Specified by:
getSchemaType
in interfaceNodeInfo
- Overrides:
getSchemaType
in classNodeWrapper
- Returns:
- For element and attribute nodes: the type annotation derived from schema validation (defaulting to xs:untyped and xs:untypedAtomic in the absence of schema validation). For comments, text nodes, processing instructions, and namespaces: null. For document nodes, either xs:untyped if the document has not been validated, or xs:anyType if it has.
- Since:
- 9.4
-
setUserData
public void setUserData(java.lang.String key, java.lang.Object value)
Set user data on the document node. The user data can be retrieved subsequently usinggetUserData(java.lang.String)
- Specified by:
setUserData
in interfaceDocumentInfo
- Parameters:
key
- A string giving the name of the property to be set. Clients are responsible for choosing a key that is likely to be unique. Must not be null. Keys used internally by Saxon are prefixed "saxon:".value
- The value to be set for the property. May be null, which effectively removes the existing value for the property.
-
getUserData
public java.lang.Object getUserData(java.lang.String key)
Get user data held in the document node. This retrieves properties previously set usingsetUserData(java.lang.String, java.lang.Object)
- Specified by:
getUserData
in interfaceDocumentInfo
- Parameters:
key
- A string giving the name of the property to be retrieved.- Returns:
- the value of the property, or null if the property has not been defined.
