Method Detail
-
setSystemId
public void setSystemId(java.lang.String uri)
Set the system id of this node.
This method is present to ensure that the class implements the javax.xml.transform.Source interface, so a node can be used as the source of a transformation.
-
setParentNode
protected void setParentNode(TinyNodeImpl parent)
Set the parent of this node. Providing this information is useful, if it is known, because otherwise getParent() has to search backwards through the document.
-
isSameNodeInfo
public boolean isSameNodeInfo(NodeInfo other)
Determine whether this is the same node as another node- Specified by:
isSameNodeInfo
in interfaceNodeInfo
- Specified by:
isSameNodeInfo
in classAbstractNode
- Returns:
- true if this Node object and the supplied Node object represent the same node in the tree.
-
getSystemId
public java.lang.String getSystemId()
Get the system ID for the entity containing the node.- Specified by:
getSystemId
in interfaceNodeInfo
- Specified by:
getSystemId
in interfacejavax.xml.transform.Source
- Specified by:
getSystemId
in interfacejavax.xml.transform.SourceLocator
- Specified by:
getSystemId
in classAbstractNode
- Returns:
- the System Identifier of the entity in the source document containing the node, or null if not known. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot.
-
getBaseURI
public java.lang.String getBaseURI()
Get the base URI for the node. Default implementation for child nodes gets the base URI of the parent node.- Specified by:
getBaseURI
in interfaceorg.w3c.dom.Node
- Specified by:
getBaseURI
in interfaceNodeInfo
- Specified by:
getBaseURI
in classAbstractNode
-
getOriginatingNode
public org.w3c.dom.Node getOriginatingNode()
Get the node corresponding to this javax.xml.transform.dom.DOMLocator- Specified by:
getOriginatingNode
in interfacejavax.xml.transform.dom.DOMLocator
- Overrides:
getOriginatingNode
in classAbstractNode
-
setLineNumber
public void setLineNumber(int line)
Set the line number of the node within its source document entity
-
getLineNumber
public int getLineNumber()
Get the line number of the node within its source document entity- Specified by:
getLineNumber
in interfaceNodeInfo
- Specified by:
getLineNumber
in interfacejavax.xml.transform.SourceLocator
- Overrides:
getLineNumber
in classAbstractNode
- Returns:
- the line number of the node in its original source document; or -1 if not available
-
getSequenceNumber
protected long getSequenceNumber()
Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. The sequence number must be unique within the document (not, as in previous releases, within the whole document collection)
-
compareOrder
public final int compareOrder(NodeInfo other)
Determine the relative position of this node and another node, in document order. The other node will always be in the same document.- Specified by:
compareOrder
in interfaceNodeInfo
- Specified by:
compareOrder
in classAbstractNode
- Parameters:
other
- The other node, whose position is to be compared with this node- Returns:
- -1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())
-
getFingerprint
public int getFingerprint()
Get the fingerprint of the node, used for matching names- Specified by:
getFingerprint
in interfaceNodeInfo
- Specified by:
getFingerprint
in classAbstractNode
-
getNameCode
public int getNameCode()
Get the name code of the node, used for matching names- Specified by:
getNameCode
in interfaceNodeInfo
- Specified by:
getNameCode
in classAbstractNode
