initialise
public void initialise(int nameCode, AttributeCollectionImpl atts, NodeInfo parent, java.lang.String baseURI, int lineNumber, int sequenceNumber)
Initialise a new ElementWithAttributes with an element name and attribute list- Overrides:
initialise
in classElementImpl
- Parameters:
nameCode
- The element name, with namespaces resolvedatts
- The attribute list, after namespace processingparent
- The parent nodebaseURI
- The base URI of the new elementlineNumber
- The line number of the element in the source documentsequenceNumber
- Integer identifying this element within the document
-
setNamespaceDeclarations
public void setNamespaceDeclarations(int[] namespaces, int namespacesUsed)
Set the namespace declarations for the element
-
getURIForPrefix
public java.lang.String getURIForPrefix(java.lang.String prefix, boolean useDefault)
Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.- Parameters:
prefix
- the namespace prefix. May be the zero-length string, indicating that there is no prefix. This indicates either the default namespace or the null namespace, depending on the value of useDefault.useDefault
- true if the default namespace is to be used when the prefix is "". If false, the method returns "" when the prefix is "".- Returns:
- the uri for the namespace, or null if the prefix is not in scope. The "null namespace" is represented by the pseudo-URI "".
-
iteratePrefixes
public java.util.Iterator iteratePrefixes()
Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate
-
getURICodeForPrefix
public short getURICodeForPrefix(java.lang.String prefix) throws NamespaceException
Search the NamespaceList for a given prefix, returning the corresponding URI.- Parameters:
prefix
- The prefix to be matched. To find the default namespace, supply ""- Returns:
- The URI code corresponding to this namespace. If it is an unnamed default namespace, return Namespace.NULL_CODE.
- Throws:
NamespaceException
- if the prefix has not been declared on this NamespaceList.
-
getPrefixForURI
public java.lang.String getPrefixForURI(java.lang.String uri)
Search the NamespaceList for a given URI, returning the corresponding prefix.- Parameters:
uri
- The URI to be matched.- Returns:
- 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.
-
sendNamespaceDeclarations
public void sendNamespaceDeclarations(Receiver out, boolean includeAncestors) throws XPathException
Output all namespace nodes associated with this element.- Specified by:
sendNamespaceDeclarations
in interfaceNodeInfo
- Overrides:
sendNamespaceDeclarations
in classElementImpl
- Parameters:
out
- The relevant outputterincludeAncestors
- True if namespaces declared on ancestor elements must- Throws:
XPathException
-
getDeclaredNamespaces
public int[] getDeclaredNamespaces(int[] buffer)
Get all namespace undeclarations and undeclarations defined on this element.- Specified by:
getDeclaredNamespaces
in interfaceNodeInfo
- Overrides:
getDeclaredNamespaces
in classElementImpl
- Parameters:
buffer
- If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.- Returns:
- An array of integers representing the namespace declarations and undeclarations present on
this element. For a node other than an element, return null. Otherwise, the returned array is a
sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The
top half word of each namespace code represents the prefix, the bottom half represents the URI.
If the bottom half is zero, then this is a namespace undeclaration rather than a declaration.
The XML namespace is never included in the list. If the supplied array is larger than required,
then the first unused entry will be set to -1.
For a node other than an element, the method returns null.
-
getInScopeNamespaceCodes
public int[] getInScopeNamespaceCodes()
Get the list of in-scope namespaces for this element as an array of namespace codes. (Used by LiteralResultElement)
-
getAttributeList
public AttributeCollection getAttributeList()
Get the attribute list for this element.- Overrides:
getAttributeList
in classElementImpl
- Returns:
- 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 java.lang.String getAttributeValue(int fingerprint)
Get the value of a given attribute of this node- Specified by:
getAttributeValue
in interfaceNodeInfo
- Overrides:
getAttributeValue
in classNodeImpl
- Parameters:
fingerprint
- The fingerprint of the attribute name- Returns:
- the attribute value if it exists or null if not
-
copy
public void copy(Receiver out, int whichNamespaces, boolean copyAnnotations, int locationId) throws XPathException
Copy this node to a given outputter (supporting xsl:copy-of)- Specified by:
copy
in interfaceNodeInfo
- Overrides:
copy
in classElementImpl
- Parameters:
out
- The outputterwhichNamespaces
- indicates which namespaces should be output: all, none, or local namespaces only (those not declared on the parent element)copyAnnotations
- indicates whether the type annotations of element and attribute nodes should be copiedlocationId
- 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
