Method Details
-
getSequenceNumber
protected final long getSequenceNumber()Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and roots) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position.- Overrides:
getSequenceNumber
in classNodeImpl
-
hasChildNodes
public final boolean hasChildNodes()Determine if the node has any children.- Specified by:
hasChildNodes
in interfaceNode
- Specified by:
hasChildNodes
in interfaceNodeInfo
- Overrides:
hasChildNodes
in classNodeImpl
- Returns:
true
if the node has any children,false
if the node has no children.
-
enumerateChildren
Get an enumeration of the children of this node -
getFirstChild
Get the first child node of the element- Specified by:
getFirstChild
in interfaceNode
- Overrides:
getFirstChild
in classNodeImpl
- Returns:
- the first child node of the required type, or null if there are no children
-
getLastChild
Get the last child node of the element- Specified by:
getLastChild
in interfaceNode
- Overrides:
getLastChild
in classNodeImpl
- Returns:
- the last child of the element, or null if there are no children
-
getChildNodes
Return aNodeList
that contains all children of this node. If there are no children, this is aNodeList
containing no nodes.- Specified by:
getChildNodes
in interfaceNode
- Overrides:
getChildNodes
in classNodeImpl
-
getNthChild
Get the nth child node of the element (numbering from 0)- Returns:
- the last child of the element, or null if there is no n'th child
-
getStringValue
Return the string-value of the node, that is, the concatenation of the character content of all descendent elements and text nodes.- Returns:
- the accumulated character content of the element, including descendant elements.
-
copyStringValue
Copy the string-value of this node to a given outputter- Specified by:
copyStringValue
in interfaceNodeInfo
- Overrides:
copyStringValue
in classAbstractNode
- Throws:
TransformerException
-
useChildrenArray
Supply an array to be used for the array of children. For system use only. -
addChild
Add a child node to this node. For system use only. Note: normalizing adjacent text nodes is the responsibility of the caller. -
removeChild
public void removeChild(int index) Remove node at given index. Will always be followed by a renumberChildren(). -
renumberChildren
public void renumberChildren()Renumber the children of a given parent node. For system use only -
dropChildren
public void dropChildren()Drop a branch of the tree. The target element remains in the tree, but its children are disconnected from the parent. Unless there are other references to the children (e.g. in a variable) they will be deleted from memory next time the garbage collector comes round. -
compact
public void compact(int size) Compact the space used by this node -
getNodeValue
Get the node value as defined in the DOM. This is not the same as the XPath string-value.- Specified by:
getNodeValue
in interfaceNode
- Overrides:
getNodeValue
in classAbstractNode
