public FleetingDocumentNode(long docNr)

Method Detail

getRootNode

public NodeInfo getRootNode()

Get the NodeInfo object representing the document node at the root of the tree

Specified by:

getRootNode in interface TreeInfo

Returns:

the document node

getTreeInfo

public TreeInfo getTreeInfo()

Description copied from class: FleetingNode

Get information about the tree to which this NodeInfo belongs

Specified by:

getTreeInfo in interface NodeInfo

Overrides:

getTreeInfo in class FleetingNode

Returns:

the TreeInfo

allocateNodeNumber

protected int allocateNodeNumber()

getDocumentNumber

public long getDocumentNumber()

Get the document number, which identifies this tree uniquely within a Configuration

Specified by:

getDocumentNumber in interface TreeInfo

Returns:

the document number

setConfiguration

public void setConfiguration(Configuration config)

Set the configuration

Parameters:

config - the configuration to which this document belongs

selectID

public NodeInfo selectID(String id,
                boolean getParent)

Get the element with a given ID, if any

Specified by:

selectID in interface TreeInfo

Parameters:

id - the required ID value

getParent - true if the element required is the parent of the element whose type is xs:ID

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)

isTyped

public boolean isTyped()

Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED

Specified by:

isTyped in interface TreeInfo

Returns:

true if the document contains elements whose type is other than UNTYPED

atomize

public AtomicSequence atomize()
                       throws XPathException

Get the typed value.

Specified by:

atomize in interface Item

Specified by:

atomize in interface NodeInfo

Overrides:

atomize in class FleetingNode

Returns:

the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.

Throws:

XPathException - if the node has no typed value, for example if it is an element node with element-only content

getUnparsedEntityNames

public Iterator<String> getUnparsedEntityNames()

Get the list of unparsed entities defined in this document

Specified by:

getUnparsedEntityNames in interface TreeInfo

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 TreeInfo

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

Specified by:

getConfiguration in interface TreeInfo

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

Overrides:

getNamePool in class FleetingNode

Returns:

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

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 - Define how namespaces are handled

locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information

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 Source

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface Location

Specified by:

getSystemId in interface NodeInfo

Specified by:

getSystemId in interface Locator

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

getAccumulatorWatchMap

public Map<Accumulator,AccumulatorWatch> getAccumulatorWatchMap()

Get a mapping from accumulators to the AccumulatorWatch that implements the accumulator.

Returns:

a mapping from accumulators to the corresponding AccumulatorWatch

setAccumulatorWatchMap

public void setAccumulatorWatchMap(Map<Accumulator,AccumulatorWatch> accumulatorWatchMap)

Set a mapping from accumulators to the AccumulatorWatch that implements the accumulator.

Parameters:

accumulatorWatchMap - a mapping from accumulators to the corresponding AccumulatorWatch

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)

Specified by:

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.
