void checkChildType(int type)
              throws org.w3c.dom.DOMException

Specified by:

checkChildType in class ParentNode

Throws:

org.w3c.dom.DOMException

writeXml

public void writeXml(XmlWriteContext context)
              throws IOException

Description copied from interface: XmlWritable

This is the primary method used to write an object and its children as XML text. Implementations with children should use writeChildrenXml to write those children, to allow selective overriding.

Specified by:

writeXml in interface XmlWritable

Throws:

IOException

getNodeType

public short getNodeType()

Specified by:

getNodeType in interface org.w3c.dom.Node

getNodeName

public String getNodeName()

Specified by:

getNodeName in interface org.w3c.dom.Node

cloneNode

public org.w3c.dom.Node cloneNode(boolean deep)

Specified by:

cloneNode in interface org.w3c.dom.Node

trimToSize

public void trimToSize()

Called to minimize space utilization. Affects only this node; children must be individually trimmed.

reduceWaste

void reduceWaste()

writeChildrenXml

public void writeChildrenXml(XmlWriteContext context)
                      throws IOException

Writes each of the child nodes. For element nodes, this adds whitespace to indent non-text children (it prettyprints) unless the xml:space='preserve' attribute applies, or the write context disables prettyprinting.

Specified by:

writeChildrenXml in interface XmlWritable

Overrides:

writeChildrenXml in class NodeBase

Parameters:

context - describes how the children should be printed

Throws:

IOException

                                     org.w3c.dom.Node refChild)
                              throws org.w3c.dom.DOMException

DOM: Inserts the new child before the specified child, which if null indicates appending the new child to the current set of children. The new child must belong to this particular document. If the newChild is already in the tree, it is first removed.

Specified by:

insertBefore in interface org.w3c.dom.Node

Overrides:

insertBefore in class NodeBase

Parameters:

newChild - the new child to be inserted

refChild - node before which newChild is to be inserted

replaceChild

public org.w3c.dom.Node replaceChild(org.w3c.dom.Node newChild,
                                     org.w3c.dom.Node refChild)
                              throws org.w3c.dom.DOMException

refChild - node which is to be replaced

Throws:

org.w3c.dom.DOMException - thrown always.

public org.w3c.dom.Node removeChild(org.w3c.dom.Node oldChild)
                             throws org.w3c.dom.DOMException

DOM: removes child if present, returning argument.

Specified by:

removeChild in interface org.w3c.dom.Node

Overrides:

removeChild in class NodeBase

Parameters:

oldChild - the node which is to be removed

Throws:

org.w3c.dom.DOMException - thrown always.

getElementsByTagName

public org.w3c.dom.NodeList getElementsByTagName(String tagname)

DOM: Returns a "live" list view of the elements below this one which have the specified tag name. Because this is "live", this API is dangerous -- indices are not stable in the face of most tree updates. Use a TreeWalker instead.

Parameters:

tagname - the tag name to show; or "*" for all elements.

Returns:

list of such elements

getElementsByTagNameNS

public org.w3c.dom.NodeList getElementsByTagNameNS(String namespaceURI,
                                                   String localName)

Since:

DOM Level 2

getIndexOf

Returns the index of the node in the list of children, such that item() will return that child.

Specified by:

getIndexOf in interface NodeEx

Overrides:

getIndexOf in class NodeBase

Parameters:

maybeChild - the node which may be a child of this one

Returns:

the index of the node in the set of children, or else -1 if that node is not a child

normalize

public void normalize()

Description copied from class: NodeBase

DOM2: noop.

Specified by:

normalize in interface org.w3c.dom.Node

Overrides:

normalize in class NodeBase

Since:

DOM Level 2 In DOM2, normalize() was generalized and got moved to Node. XXX Comments below are old: DOM2: Merges all adjacent Text nodes in the tree rooted by this element. Avoid using this on large blocks of text not separated by markup such as elements or processing instructions, since it can require arbitrarily large blocks of contiguous memory. XXX The following extension breaks a DOM conformance test so the code has been modified to not behave as described:

As a compatible extension to DOM, this normalizes treatment of whitespace except when the xml:space='preserve' attribute value applies to a node. All whitespace is normalized to one space. This ensures that text which is pretty-printed and then reread (and normalized) retains the same content.

removeWhiteSpaces

public int removeWhiteSpaces(char[] buf)

getParentImpl

ParentNode getParentImpl()

isReadonly

public boolean isReadonly()

Description copied from interface: NodeEx

Method to allow easy determination of whether a node is read only.

Specified by:

isReadonly in interface NodeEx

Returns:

true if the node is read only

setReadonly

public void setReadonly(boolean deep)

Description copied from interface: NodeEx

Sets the node to be readonly; applies recursively to the children of this node if the parameter is true.

Specified by:

setReadonly in interface NodeEx

Parameters:

deep - If true recursively set the nodes in the subtree under the current node to be read only. If false then set only the current node to be readonly

getLanguage

public String getLanguage()

Returns the language id (value of xml:lang attribute) applicable to this node, if known. Traces up through ancestors as needed.

Specified by:

getLanguage in interface NodeEx

Returns:

the value of the xml:lang attribute, or null if no such attribute is found.

getInheritedAttribute

public String getInheritedAttribute(String name)

Returns the value of a given attribute, tracing up through ancestors if needed. In the XML standard, two attributes are inherited: xml:lang and xml:space. This mechanism can also be involved with Cascading Style Sheets (CSS). The current version of XML Namespaces also uses inheritance.

Specified by:

getInheritedAttribute in interface NodeEx

Parameters:

name - identifies the attribute; colons may be included, but namespace prefixes are not interpreted

Returns:

the value of the inherited attribute, or null if no value was inherited.

getParentNode

public org.w3c.dom.Node getParentNode()

DOM: Returns the node's parent. This will be null in cases such as newly created or removed nodes, and for attributes, fragments, and documents.

Specified by:

getParentNode in interface org.w3c.dom.Node

setParentNode

void setParentNode(ParentNode arg,
                   int index)
             throws org.w3c.dom.DOMException

Throws:

org.w3c.dom.DOMException

getOwnerDocument

public org.w3c.dom.Document getOwnerDocument()

DOM: Returns the document to which this node belongs.

Specified by:

getOwnerDocument in interface org.w3c.dom.Node

setNodeValue

public void setNodeValue(String value)

public String getNodeValue()

DOM: Returns null; overridden by subclasses as needed.

Specified by:

getNodeValue in interface org.w3c.dom.Node

getChildNodes

public org.w3c.dom.NodeList getChildNodes()

DOM: Returns an object which permits "live" access to all this node's children.

In this implementation, nodes provide such access without needing another node as an intermediary; "this" is returned.

Specified by:

getChildNodes in interface org.w3c.dom.Node

getNextSibling

public org.w3c.dom.Node getNextSibling()

DOM: Returns the node immediately following this node in a breadth first traversal of the tree, or null if there is no such sibling. In this implementation, sibling access from a node is slower than indexed access from its parent.

Specified by:

getNextSibling in interface org.w3c.dom.Node

getPreviousSibling

public org.w3c.dom.Node getPreviousSibling()

DOM: Returns the node immediately preceding this node in a breadth first traversal of the tree, or null if there is no such sibling. In this implementation, sibling access from a node is slower than indexed access from its parent.

DOM2: returns null. Overridden by subclasses that support namespaces.

Specified by:

getLocalName in interface org.w3c.dom.Node
