public interface FingerprintedNode
extends NodeInfo

This is a marker interface used to identify nodes that contain a namepool fingerprint. Although all nodes are capable of returning a fingerprint, some (notably DOM, XOM, and JDOM nodes) need to calculate it on demand. A node that implements this interface indicates that obtaining the fingerprint for use in name comparisons is more efficient than using the URI and local name.

Method Detail

getConfiguration

Configuration getConfiguration()

Get the configuration used to build the tree containing this node.

Specified by:

getConfiguration in interface NodeInfo

Returns:

the Configuration

Since:

8.4. Moved in 9.7 from NodeInfo to FingerprintedNode

getNamePool

NamePool getNamePool()

Get the NamePool that holds the namecode for this node

Returns:

the namepool

Since:

8.4. Moved in 9.7 from NodeInfo to FingerprintedNode

getAttributeValue

String getAttributeValue(int fp)

Get the value of the attribute with a given fingerprint.

Parameters:

fp - the fingerprint of the required attribute

Returns:

the string value of the attribute if present, or null if absent

getFingerprint

int getFingerprint()

Get fingerprint. The fingerprint is a coded form of the expanded name of the node: two nodes with the same name code have the same namespace URI and the same local name. The fingerprint contains no information about the namespace prefix. For a name in the null namespace, the fingerprint is the same as the name code.

Returns:

an integer fingerprint; two nodes with the same fingerprint have the same expanded QName. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

Since:

8.4

getNameCode

int getNameCode()

Get nameCode. The fingerprint is a coded form of the expanded name of the node: two nodes with the same name code have the same namespace URI and the same local name. The nameCode contains additional information about the namespace prefix. For a name in the null namespace, the fingerprint is the same as the name code.

Returns:

an integer name code; two nodes with the same name code have the same prefix, local name, and namespace URI. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

Since:

8.4
