Class DocumentWrapper

java.lang.Object
net.sf.saxon.option.jdom.NodeWrapper
net.sf.saxon.option.jdom.DocumentWrapper
All Implemented Interfaces:
Source, PullEvent, DocumentInfo, Item<NodeInfo>, NodeInfo, ValueRepresentation<NodeInfo>, SiblingCountingNode, VirtualNode

public class DocumentWrapper extends NodeWrapper implements DocumentInfo
The root node of an XPath tree. (Or equivalently, the tree itself).

This class should have been named Root; it is used not only for the root of a document, but also for the root of a result tree fragment, which is not constrained to contain a single top-level element.

    • wrap

      public NodeWrapper wrap(Object node)
      Wrap a node in the JDOM 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 (containing the name pool used for all names in this document)
    • getConfiguration

      public Configuration getConfiguration()
      Get the configuration previously set using setConfiguration (or the default configuraton allocated automatically)
      Specified by:
      getConfiguration in interface NodeInfo
      Overrides:
      getConfiguration in class NodeWrapper
      Returns:
      the Configuration
    • getNamePool

      public NamePool getNamePool()
      Get the name pool used for the names in this document
      Specified by:
      getNamePool in interface NodeInfo
      Overrides:
      getNamePool in class NodeWrapper
      Returns:
      the NamePool
    • getDocumentNumber

      public long getDocumentNumber()
      Get the unique document number
      Specified by:
      getDocumentNumber in interface NodeInfo
      Overrides:
      getDocumentNumber in class NodeWrapper
      Returns:
      the document number of the document containing this node
    • isTyped

      public boolean isTyped()
      Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED
      Specified by:
      isTyped in interface DocumentInfo
      Returns:
      true if the document contains elements whose type is other than UNTYPED
    • selectID

      public NodeInfo selectID(String id, boolean getParent)
      Get the element with a given ID, if any
      Specified by:
      selectID in interface DocumentInfo
      Parameters:
      id - the required ID value
      getParent -
      Returns:
      the element node with the given ID if there is one, otherwise null.
    • getUnparsedEntityNames

      public Iterator<String> getUnparsedEntityNames()
      Get the list of unparsed entities defined in this document
      Specified by:
      getUnparsedEntityNames in interface DocumentInfo
      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 String[] getUnparsedEntity(String name)
      Get the unparsed entity with a given name
      Specified by:
      getUnparsedEntity in interface DocumentInfo
      Parameters:
      name - the name of the entity
      Returns:
      null: JDOM does not provide access to unparsed entities
    • getTypeAnnotation

      public int getTypeAnnotation()
      Get the type annotation. Always XS_UNTYPED.
      Specified by:
      getTypeAnnotation in interface NodeInfo
      Overrides:
      getTypeAnnotation in class NodeWrapper
      Returns:
      the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated as untypedAtomic for the purposes of obtaining the typed value).

      For elements and attributes, this is the type annotation as defined in XDM. For document nodes, it should be one of XS_UNTYPED if the document has not been validated, or XS_ANY_TYPE if validation has taken place (that is, if any node in the document has an annotation other than Untyped or UntypedAtomic).

    • 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 interface NodeInfo
      Overrides:
      getSchemaType in class NodeWrapper
      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.

    • setUserData

      public void setUserData(String key, Object value)
      Set user data on the document node. The user data can be retrieved subsequently using getUserData(java.lang.String)
      Specified by:
      setUserData in interface DocumentInfo
      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 Object getUserData(String key)
      Get user data held in the document node. This retrieves properties previously set using setUserData(java.lang.String, java.lang.Object)
      Specified by:
      getUserData in interface DocumentInfo
      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.
