TinyAttributeImpl

public TinyAttributeImpl(TinyTree tree,
 int nodeNr)

Method Details

getParent

public NodeInfo getParent()

Get the parent node

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

getRoot

public NodeInfo getRoot()

Get the root node of the tree (not necessarily a document node)

Specified by:

getRoot in interface NodeInfo

Overrides:

getRoot in class TinyNodeImpl

Returns:

the NodeInfo representing the root of this tree

getSequenceNumber

protected long getSequenceNumber()

Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In this implementation, elements have a zero least-significant word, while attributes and namespaces use the same value in the top word as the containing element, and use the bottom word to hold a sequence number, which numbers namespaces first and then attributes.

Overrides:

getSequenceNumber in class TinyNodeImpl

getNodeKind

public final int getNodeKind()

Return the type of node.

Returns:

Node.ATTRIBUTE

See Also:

• Type

getStringValueCS

public CharSequence getStringValueCS()

Return the string value of the node.

Specified by:

getStringValueCS in interface Item

Specified by:

getStringValueCS in interface ValueRepresentation

Overrides:

getStringValueCS in class TinyNodeImpl

Returns:

the attribute value

See Also:

• Item.getStringValue()

getStringValue

public String getStringValue()

Return the string value of the node.

Returns:

the attribute value

See Also:

• Item.getStringValueCS()

getFingerprint

public int getFingerprint()

Get the fingerprint of the node, used for matching names

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. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

getNameCode

public int getNameCode()

Get the name code of the node, used for finding names in the name pool

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. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

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 NodeInfo

Overrides:

getPrefix in class TinyNodeImpl

Returns:

the prefix part of the name. For an unnamed node, return null.

getDisplayName

public String getDisplayName()

Get the display name of this node. For elements and attributes this is [prefix:]localname. For unnamed nodes, it is an empty string.

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.

Specified by:

getLocalPart in interface NodeInfo

Overrides:

getLocalPart in class TinyNodeImpl

Returns:

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

getURI

public final 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. For the default namespace, return an empty string

getTypeAnnotation

public int getTypeAnnotation()

Get the type annotation of this node, if any The bit NodeInfo.IS_DTD_TYPE (1invalid input: '<'invalid input: '<'30) will be set in the case of an attribute node if the type annotation is one of ID, IDREF, or IDREFS and this is derived from DTD rather than schema validation. Returns UNTYPED_ATOMIC if there is no type annotation

Specified by:

getTypeAnnotation in interface NodeInfo

Overrides:

getTypeAnnotation in class TinyNodeImpl

Returns:

the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated as untypedAtomic for the purposes of obtaining the typed value).

The result is undefined for nodes other than elements and attributes.

generateId

public void generateId(FastStringBuffer buffer)

Generate id. Returns key of owning element with the attribute namecode as a suffix

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Parameters:

buffer - Buffer to contain the generated ID value

copy

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

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 NodeInfo.NO_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.ALL_NAMESPACES

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

locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be a LocationCopier

Throws:

XPathException

getLineNumber

public int getLineNumber()

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

Specified by:

getLineNumber in interface NodeInfo

Specified by:

getLineNumber in interface SourceLocator

Overrides:

getLineNumber in class TinyNodeImpl

Returns:

the line number of the node in its original source document; or -1 if not available

isId

public boolean isId()

Determine whether this node has the is-id property

Specified by:

isId in interface ExtendedNodeInfo

Overrides:

isId in class TinyNodeImpl

Returns:

true if the node is an ID

isIdref

public boolean isIdref()

Determine whether this node has the is-idref property

Specified by:

isIdref in interface ExtendedNodeInfo

Overrides:

isIdref in class TinyNodeImpl

Returns:

true if the node is an IDREF or IDREFS element or attribute
