Constructor Detail

FleetingDocumentNode

public FleetingDocumentNode(int docNr)
Method Detail

allocateNodeNumber

protected int allocateNodeNumber()

setConfiguration

public void setConfiguration(Configuration config)
Set the configuration


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 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 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:
if the entity exists, return an array of two Strings, the first holding the system ID of the entity (as an absolute URI if possible), the second holding the public ID if there is one, or null if not. If the entity does not exist, the method returns null. Applications should be written on the assumption that this array may be extended in the future to provide additional information.
Since:
8.4

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 Source
Overrides:
setSystemId in class FleetingNode
Parameters:
systemId - The system identifier as a URL string.

getConfiguration

public Configuration getConfiguration()
Get the configuration used to build the tree containing this node.

Specified by:
getConfiguration in interface NodeInfo
Overrides:
getConfiguration in class FleetingNode
Returns:
the Configuration
Since:
8.4

getNamePool

public NamePool getNamePool()
Get the NamePool that holds the namecode for this node

Specified by:
getNamePool in interface NodeInfo
Overrides:
getNamePool in class FleetingNode
Returns:
the namepool
Since:
8.4

getDocumentNumber

public long getDocumentNumber()
Get the document number of the document containing this node. For a free-standing orphan node, just return the hashcode.

Specified by:
getDocumentNumber in interface NodeInfo
Overrides:
getDocumentNumber in class FleetingNode
Returns:
the document number of the document containing this node
Since:
8.4

copy

public void copy(Receiver out,
                 int copyOptions,
                 int 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
Overrides:
copy in class FleetingNode
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 -
locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be
Throws:
XPathException

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 Source
Specified by:
getSystemId in interface NodeInfo
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.
Since:
8.4

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.
