Constructor Detail

TinyDocumentImpl

public TinyDocumentImpl(TinyTree tree)

Method Detail

getTree

public TinyTree getTree()

Get the tree containing this node

setConfiguration

public void setConfiguration(Configuration config)

Set the Configuration that contains this document

getConfiguration

public Configuration getConfiguration()

Get the configuration previously set using setConfiguration

Specified by:

getConfiguration in interface NodeInfo

Overrides:

getConfiguration in class TinyNodeImpl

Returns:

the Configuration

setSystemId

public void setSystemId(String uri)

Set the system id of this node

Specified by:

setSystemId in interface Source

Overrides:

setSystemId in class TinyNodeImpl

getSystemId

public String getSystemId()

Get the system id of this root node

Specified by:

getSystemId in interface Source

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface NodeInfo

Overrides:

getSystemId in class TinyNodeImpl

Returns:

the System Identifier of the entity in the source document containing the node, or null if not known.

getBaseURI

public String getBaseURI()

Get the base URI of this root node. For a root node the base URI is the same as the System ID.

Specified by:

getBaseURI in interface NodeInfo

Overrides:

getBaseURI in class TinyNodeImpl

Returns:

the base URI of the node. This may be null if the base URI is unknown.

getLineNumber

public int getLineNumber()

Get the line number of this root node.

Specified by:

getLineNumber in interface SourceLocator

Specified by:

getLineNumber in interface NodeInfo

Overrides:

getLineNumber in class TinyNodeImpl

Returns:

0 always

getNodeKind

public final int getNodeKind()

Return the type of node.

Specified by:

getNodeKind in interface NodeInfo

Returns:

Type.DOCUMENT (always)

See Also:

Type

getParent

public NodeInfo getParent()

Find the parent node of this node.

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

getRoot

public NodeInfo getRoot()

Get the root node

Specified by:

getRoot in interface NodeInfo

Overrides:

getRoot in class TinyNodeImpl

Returns:

the NodeInfo that is the root of the tree - not necessarily a document node

getDocumentRoot

public DocumentInfo getDocumentRoot()

Get the root (document) node

Specified by:

getDocumentRoot in interface NodeInfo

Overrides:

getDocumentRoot in class TinyNodeImpl

Returns:

the DocumentInfo representing the document node, or null if the root of the tree is not a document node

generateId

public void generateId(FastStringBuffer buffer)

Get a character string that uniquely identifies this node

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Parameters:

buffer - to contain an identifier based on the document number

getAllElements

AxisIterator getAllElements(int fingerprint)

Get a list of all elements with a given name. This is implemented as a memo function: the first time it is called for a particular element type, it remembers the result for next time.

getElementList

List getElementList(int fingerprint)

Get a list containing all the elements with a given element name

Parameters:

fingerprint - the fingerprint of the element name

Returns:

list a List containing the TinyElementImpl objects

registerID

void registerID(NodeInfo e,
                String id)

Register a unique element ID. Fails if there is already an element with that ID.

Parameters:

e - The NodeInfo (always an element) having a particular unique ID value

id - The unique ID value. The caller is responsible for checking that this is a valid NCName.

selectID

public NodeInfo selectID(String id)

Get the element with a given ID.

Specified by:

selectID in interface DocumentInfo

Parameters:

id - The unique ID of the required element, previously registered using registerID()

Returns:

The NodeInfo (always an Element) for the given ID if one has been registered, otherwise null.

setUnparsedEntity

void setUnparsedEntity(String name,
                       String uri,
                       String publicId)

Set an unparsed entity URI associated with this document. For system use only, while building the document.

getUnparsedEntity

public String[] getUnparsedEntity(String name)

Get the unparsed entity with a given nameID if there is one, or null if not. If the entity does not exist, return null.

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, the second holding the public

copy

public void copy(Receiver out,
                 int whichNamespaces,
                 boolean copyAnnotations,
                 int locationId)
          throws XPathException

Copy this node to a given outputter

Specified by:

copy in interface NodeInfo

Parameters:

out - the Receiver to which the node should be copied

whichNamespaces - in the case of an element, controls which namespace nodes should be copied. Values are NodeInfo.NO_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.ALL_NAMESPACES

copyAnnotations - indicates whether the type annotations of element and attribute nodes should be copied

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 a LocationCopier

Throws:

XPathException
