Constructor Detail

FleetingDocumentNode

public FleetingDocumentNode()

Method Detail

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

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
