    • setSystemId

      public void setSystemId(String systemId)
      Set the system identifier for this Source.

      The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

      Specified by:
      setSystemId in interface NodeInfo
      Specified by:
      setSystemId in interface Source
      Overrides:

      Parameters:
      systemId - The system identifier as a URL string.

      Specified by:
      getConfiguration in interface NodeInfo
      Specified by:

      the namepool
      Since:
      8.4
    • copy

      public void copy(Receiver out, int copyOptions, Location locationId) throws XPathException
      Copy this node to a given Receiver.

      This method is primarily for internal use. It should not be considered a stable part of the Saxon API.

      Specified by:
      copy in interface NodeInfo
      Parameters:
      out - the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.
      copyOptions - Define how namespaces are handled
      locationId - If non-zero, identifies the location of the instruction
      Throws:
      XPathException - if any downstream error occurs
    • getSystemId

      public String getSystemId()
      Get the System ID for the node. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot. The base URI is used primarily for resolving relative URIs within the content of the document. The system ID is used primarily in conjunction with a line number, for identifying the location of elements within the source XML, in particular when errors are found. For a document node, the System ID represents the value of the document-uri property as defined in the XDM data model.
      Specified by:
      getSystemId in interface Location
      Specified by:
      getSystemId in interface Locator
      Specified by:
      getSystemId in interface NodeInfo
      Specified by:
      getSystemId in interface Source
      Specified by:
      getSystemId in interface SourceLocator
      Overrides:
      getSystemId in class FleetingNode
      Returns:
      the System Identifier of the entity in the source document containing the node, or null if not known or not applicable.
      Since:
      8.4
    • getBaseURI

      public String getBaseURI()
      Get the Base URI for the node, that is, the URI used for resolving a relative URI contained in the node. This will be the same as the System ID unless xml:base has been used. Where the node does not have a base URI of its own, the base URI of its parent node is returned.
      Specified by:
      getBaseURI in interface NodeInfo
      Overrides:
      getBaseURI in class FleetingNode
      Returns:
      the base URI of the node. This may be null if the base URI is unknown.

    • setSpaceStrippingRule

      public void setSpaceStrippingRule(SpaceStrippingRule rule)
      Set details of space stripping action that was applied to this document during construction. This ensures that space stripping is not applied twice to the same document.
      Specified by:
      setSpaceStrippingRule in interface TreeInfo
      Parameters:
      rule - details of the space stripping rules that have been applied to this document during its construction.
      Since:
      9.9
    • getSpaceStrippingRule

      public SpaceStrippingRule getSpaceStrippingRule()
      Get details of space stripping action that was applied to this document during construction. This ensures that space stripping is not applied twice to the same document.
      Specified by:
      getSpaceStrippingRule in interface TreeInfo
      Returns:
      details of the space stripping rules that have been applied to this document during its construction. By default, returns NoElementsSpaceStrippingRule, indicating that no space stripping has been applied
      Since:
      9.9
    • 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 TreeInfo
      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)

      getUserData in interface TreeInfo
      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.
