Constructor Detail

TinyNamespaceImpl

public TinyNamespaceImpl(TinyDocumentImpl doc,
                         int nodeNr)

Method Detail

getNamespaceCode

public int getNamespaceCode()

Get the namespace code (a numeric representation of the prefix and URI)

getFingerprint

public int getFingerprint()

Get the fingerprint

Specified by:

getFingerprint in interface NodeInfo

Overrides:

getFingerprint in class TinyNodeImpl

Returns:

an integer fingerprint; two nodes with the same fingerprint have the same expanded QName

setParentNode

protected void setParentNode(int nodeNr)

Set the parent element for this namespace node

getNameCode

public int getNameCode()

Get the nameCode, for name matching

Specified by:

getNameCode in interface NodeInfo

Overrides:

getNameCode in class TinyNodeImpl

Returns:

an integer name code, which may be used to obtain the actual node name from the name pool

See Also:

allocate, getFingerprint

getPrefix

public String getPrefix()

Get the prefix part of the name of this node. This is the name before the ":" if any.

Specified by:

getPrefix in interface Node

Overrides:

getPrefix in class TinyNodeImpl

Returns:

the prefix part of the name. Always null.

getDisplayName

public String getDisplayName()

Get the display name of this node. For namespaces this is the namespace prefix.

Specified by:

getDisplayName in interface NodeInfo

Overrides:

getDisplayName in class TinyNodeImpl

Returns:

The display name of this node. For a node with no name, return an empty string.

getLocalPart

public String getLocalPart()

Get the local name of this node. For namespaces this is the namespace prefix.

Specified by:

getLocalPart in interface NodeInfo

Overrides:

getLocalPart in class TinyNodeImpl

Returns:

The local name of this node. Returns "" for the default namespace.

getURI

public String getURI()

Get the URI part of the name of this node.

Specified by:

getURI in interface NodeInfo

Overrides:

getURI in class TinyNodeImpl

Returns:

The URI of the namespace of this node. Always null.

getParent

public NodeInfo getParent()

Get the parent element of this namespace node

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

isSameNode

public final boolean isSameNode(NodeInfo other)

Determine whether this is the same node as another node

Specified by:

isSameNode in interface NodeInfo

Overrides:

isSameNode in class TinyNodeImpl

Parameters:

other - the node to be compared with this node

Returns:

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

getNodeKind

public final int getNodeKind()

Return the type of node.

Returns:

Type.NAMESPACE

See Also:

Type

getStringValue

public final String getStringValue()

Return the string value of the node.

Specified by:

getStringValue in interface Item

Specified by:

getStringValue in interface NodeInfo

Specified by:

getStringValue in class AbstractNode

Returns:

the namespace uri

getBaseURI

public String getBaseURI()

Get the base URI for the node. In XPath 2.0, the base URI of a namespace node is (), which we represent as null.

Specified by:

getBaseURI in interface NodeInfo

Specified by:

getBaseURI in interface Node

Overrides:

getBaseURI in class TinyNodeImpl

Returns:

the base URI of the node

generateId

public String generateId()

Get unique identifier. Returns key of owning element with the namespace prefix as a suffix

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Returns:

a string.

copy

public void copy(Receiver out,
                 int whichNamespaces,
                 boolean copyAnnotations)
          throws TransformerException

Copy this node to a given outputter

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:

TransformerException

getSequenceNumber

protected 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 class TinyNodeImpl
