public abstract class AbstractNode extends java.lang.Object implements org.w3c.dom.Node, NodeInfo, javax.xml.transform.SourceLocator, javax.xml.transform.dom.DOMLocator
This class is an abstract implementation of the Saxon NodeInfo interface; it also contains concrete implementations of most of the DOM methods in terms of the NodeInfo methods. These include all the methods defined on the DOM Node class itself, and most of those defined on subclasses such as Document, Text, and Comment: because of the absence of multiple inheritance, this is the only way of making these methods reusable by multiple implementations. The class contains no data, and can be used as a common superclass for different implementations of Node and NodeInfo.- Author:

isEqualNode
public boolean isEqualNode(org.w3c.dom.Node arg)
Tests whether two nodes are equal.
This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested withNode.isSameNode()
. All nodes that are the same will also be equal, though the reverse may not be true.
Two nodes are equal if and only if the following conditions are satisfied:- The two nodes are of the same type.
- The following string
attributes are equal:
nodeName
,localName
,namespaceURI
,prefix
,nodeValue
. This is: they are bothnull
, or they have the same length and are character for character identical. - The
attributes
NamedNodeMaps
are equal. This is: they are bothnull
, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index. - The
childNodes
NodeLists
are equal. This is: they are bothnull
, or they have the same length and contain equal nodes at the same index. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
For twoDocumentType
nodes to be equal, the following conditions must also be satisfied:- The following string attributes
are equal:
publicId
,systemId
,internalSubset
. - The
entities
NamedNodeMaps
are equal. - The
notations
NamedNodeMaps
are equal.
On the other hand, the following do not affect equality: theownerDocument
,baseURI
, andparentNode
attributes, thespecified
attribute forAttr
nodes, theschemaTypeInfo
attribute forAttr
andElement
nodes, theText.isElementContentWhitespace
attribute forText
nodes, as well as any user data or event listeners registered on the nodes.Note: As a general rule, anything not mentioned in the description above is not significant in consideration of equality checking. Note that future versions of this specification may take into account more attributes and implementations conform to this specification are expected to be updated accordingly.
- Specified by:
isEqualNode
in interfaceorg.w3c.dom.Node

arg

isSameNode
public boolean isSameNode(org.w3c.dom.Node other)

references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.- Specified by:
isSameNode

replaceWholeText
public org.w3c.dom.Text replaceWholeText(java.lang.String content) throws org.w3c.dom.DOMException
Replaces the text of the current node and all logically-adjacent text nodes with the specified text. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.
This method returns the node which received the replacement text. The returned node is:null
, when the replacement text is the empty string;- the current node, except when the current node is read-only;
- a new
Text
node of the same type (Text
orCDATASection
) as the current node inserted at the location of the replacement.
For instance, in the above example callingreplaceWholeText
on theText
node that contains "bar" with "yo" in argument results in the following:
Where the nodes to be removed are read-only descendants of anEntityReference
, theEntityReference
must be removed instead of the read-only nodes. If anyEntityReference
to be removed has descendants that are notEntityReference
,Text
, orCDATASection
nodes, thereplaceWholeText
method must fail before performing any modification of the document, raising aDOMException
with the codeNO_MODIFICATION_ALLOWED_ERR
.
For instance, in the example below callingreplaceWholeText
on theText
node that contains "bar" fails, because theEntityReference
node "ent" contains anElement
node which cannot be removed.- Parameters:
content
- The content of the replacingText
node.- Returns:
- The
Text
node created with the specified content. - Throws:
org.w3c.dom.DOMException
- NO_MODIFICATION_ALLOWED_ERR: Raised if one of theText
nodes being replaced is readonly.- Since:
- DOM Level 3
-
setIdAttribute
public void setIdAttribute(java.lang.String name, boolean isId) throws org.w3c.dom.DOMException
If the parameterisId
istrue
, this method declares the specified attribute to be a user-determined ID attribute . This affects the value ofAttr.isId
and the behavior ofDocument.getElementById
, but does not change any schema that may be in use, in particular this does not affect theAttr.schemaTypeInfo
of the specifiedAttr
node. Use the valuefalse
for the parameterisId
to undeclare an attribute for being a user-determined ID attribute.
To specify an attribute by local name and namespace URI, use thesetIdAttributeNS
method.- Parameters:
name
- The name of the attribute.isId
- Whether the attribute is a of type ID.- Throws:
org.w3c.dom.DOMException
- NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if the specified node is not an attribute of this element.- Since:
- DOM Level 3
-
setIdAttributeNode
public void setIdAttributeNode(org.w3c.dom.Attr idAttr, boolean isId) throws org.w3c.dom.DOMException
If the parameterisId
istrue
, this method declares the specified attribute to be a user-determined ID attribute . This affects the value ofAttr.isId
and the behavior ofDocument.getElementById
, but does not change any schema that may be in use, in particular this does not affect theAttr.schemaTypeInfo
of the specifiedAttr
node. Use the valuefalse
for the parameterisId
to undeclare an attribute for being a user-determined ID attribute.- Parameters:
idAttr
- The attribute node.isId
- Whether the attribute is a of type ID.- Throws:
org.w3c.dom.DOMException
- NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if the specified node is not an attribute of this element.- Since:
- DOM Level 3

setIdAttributeNS
public void setIdAttributeNS(java.lang.String namespaceURI, java.lang.String localName, boolean isId) throws org.w3c.dom.DOMException
If the parameterisId
istrue

and the behavior ofDocument.getElementById
, but does not change any schema that may be in use, in particular this does not affect theAttr.schemaTypeInfo

- The namespace URI of the attribute.localName
- The local name of the attribute.isId
- Whether the attribute is a of type ID.- Throws:
