ElementImpl implements an element with no attributes or namespace declarations.
This class is an implementation of NodeInfo. For elements with attributes or
namespace declarations, class ElementWithAttributes is used.
addNamespaceNodes
public void addNamespaceNodes(ElementImpl owner,
Vector list,
boolean addXML)
Make the set of all namespace nodes associated with this element.
owner
- The element owning these namespace nodes.list
- a Vector containing NamespaceImpl objects representing the namespaces
in scope for this element; the method appends nodes to this Vector, which should
initially be empty. Note that the returned list will never contain the XML namespace
(to get this, the NamespaceEnumeration class adds it itself). The list WILL include
an entry for the undeclaration xmlns=""; again it is the job of NamespaceEnumeration
to ignore this, since it doesn't represent a true namespace node.addXML
- Add the XML namespace node to the list
copy
public void copy(Outputter out)
throws TransformerException
Copy this node to a given outputter (supporting xsl:copy-of)
- copy in interface NodeInfo
copy
public void copy(Outputter out,
boolean allNamespaces)
throws TransformerException
Copy this node to a given outputter (supporting xsl:copy-of)
out
- The outputterallNamespaces
- true if namespaces for ancestor nodes must be output
generateId
public String generateId()
Get a character string that uniquely identifies this node within this document
(The calling code will prepend a document identifier)
- generateId in interface NodeInfo
- generateId in interface NodeImpl
- a string.
getAttributeList
public AttributeCollection getAttributeList()
Get the attribute list for this element.
- The attribute list. This will not include any
namespace attributes. The attribute names will be in expanded form, with prefixes
replaced by URIs
getAttributeValue
public String getAttributeValue(String name)
Find the value of a given attribute of this element.
This is a short-cut method; the full capability to examine
attributes is offered via the getAttributeList() method.
The attribute may either be one that was present in the original XML document,
or one that has been set by the application using setAttribute().
name
- the name of an attribute. There must be no prefix in the name.
- the value of the attribute, if it exists, otherwise null
getBaseURI
public String getBaseURI()
Get the base URI of this element node. This will be the same as the System ID unless
xml:base has been used.
- getBaseURI in interface NodeInfo
- getBaseURI in interface NodeImpl
getLineNumber
public int getLineNumber()
Get the line number of the node within its source document entity
- getLineNumber in interface NodeInfo
- getLineNumber in interface NodeImpl
getNameCode
public int getNameCode()
Get the nameCode of the node. This is used to locate the name in the NamePool
- getNameCode in interface NodeInfo
- getNameCode in interface NodeImpl
getNodeType
public final short getNodeType()
Return the type of node.
- getNodeType in interface NodeInfo
- NodeInfo.ELEMENT
getPrefixForURI
public String getPrefixForURI(String uri)
Search the NamespaceList for a given URI, returning the corresponding prefix.
uri
- The URI to be matched.
- The prefix corresponding to this URI. If not found, return null. If there is
more than one prefix matching the URI, the first one found is returned. If the URI matches
the default namespace, return an empty string.
getSystemId
public final String getSystemId()
Get the system ID of the entity containing this element node.
- getSystemId in interface NodeInfo
- getSystemId in interface NodeImpl
getURICodeForPrefix
public short getURICodeForPrefix(String prefix)
throws NamespaceException
Search the NamespaceList for a given prefix, returning the corresponding URI.
prefix
- The prefix to be matched. To find the default namespace, supply ""
- The URI code corresponding to this namespace. If it is an unnamed default namespace,
return Namespace.NULL_CODE.
NamespaceException
- if the prefix has not been declared on this NamespaceList.
initialise
public void initialise(int nameCode,
AttributeCollection atts,
NodeInfo parent,
String baseURI,
int lineNumber,
int sequenceNumber)
Initialise a new ElementImpl with an element name
atts
- The attribute list: always nullparent
- The parent node
makeNameCode
public final int makeNameCode(String qname,
boolean useDefault)
throws NamespaceException
Make a NameCode, using this Element as the context for namespace resolution.
The name will be entered in the namepool: therefore this method should not be
called once the name pool is sealed.
qname
- The name as written, in the form "[prefix:]localname"
outputNamespaceNodes
public void outputNamespaceNodes(Outputter out,
boolean includeAncestors)
throws TransformerException
Output all namespace nodes associated with this element.
- outputNamespaceNodes in interface NodeInfo
- outputNamespaceNodes in interface NodeImpl
out
- The relevant outputter
setAttribute
public void setAttribute(String name,
String value)
throws DOMException
Set the value of an attribute on the current element.
setLineNumber
public void setLineNumber(int line)
Set the line number of the element within its source document entity
setNameCode
public void setNameCode(int nameCode)
Set the name code. Used when creating a dummy element in the Stripper
setSystemId
public void setSystemId(String uri)
Set the system ID of this node. This method is provided so that a NodeInfo
implements the javax.xml.transform.Source interface, allowing a node to be
used directly as the Source of a transformation
- setSystemId in interface NodeImpl
