Method Detail

getStringValue

public java.lang.String getStringValue()

Description copied from class: AbstractNode

Get the string value of the node

Specified by:

getStringValue in interface NodeInfo

Specified by:

getStringValue in class AbstractNode

getNodeKind

public final int getNodeKind()

Description copied from interface: NodeInfo

Get the kind of node. This will be a value such as Type.ELEMENT or Type.ATTRIBUTE

Specified by:

getNodeKind in interface NodeInfo

Returns:

an integer identifying the kind of node. These integer values are the same as those used in the DOM

Type

copy

public void copy(Receiver out,
                 int whichNamespaces,
                 boolean copyAnnotations)
          throws javax.xml.transform.TransformerException

Copy this node to a given outputter

Specified by:

copy in interface NodeInfo

Parameters:

out - the Receiver to which the node should be copied

whichNamespaces - in the case of an element, controls which namespace nodes should be copied. Values are NO_NAMESPACES, LOCAL_NAMESPACES, ALL_NAMESPACES

copyAnnotations - indicates whether the type annotations of element and attribute nodes should be copied

Throws:

javax.xml.transform.TransformerException

getTarget

public java.lang.String getTarget()

The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.

Specified by:

getTarget in interface org.w3c.dom.ProcessingInstruction

getData

public java.lang.String getData()

The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?> .

Specified by:

getData in interface org.w3c.dom.ProcessingInstruction

Overrides:

getData in class AbstractNode

setData

public void setData(java.lang.String data)
             throws org.w3c.dom.DOMException

Set the content of this PI. Always fails.

Specified by:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

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.

isSameNode

public boolean isSameNode(NodeInfo other)

Determine whether this is the same node as another node

Specified by:

isSameNode in interface NodeInfo

Specified by:

isSameNode in class AbstractNode

Returns:

true if this Node object and the supplied Node object represent the same node in the tree.

public java.lang.String getSystemId()

Get the system ID for the entity containing the node.

Specified by:

getSystemId in interface NodeInfo

Specified by:

getSystemId in class AbstractNode

getBaseURI

public java.lang.String getBaseURI()

Get the line number of the node within its source document entity

Specified by:

getLineNumber in interface NodeInfo

Overrides:

getLineNumber in class AbstractNode

Specified by:

compareOrder in interface NodeInfo

Specified by:

compareOrder in class AbstractNode

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())

Get the fingerprint of the node, used for matching names

Specified by:

getFingerprint in interface NodeInfo

Specified by:

getFingerprint in class AbstractNode

getNameCode
