Constructor Detail

WhitespaceTextImpl

public WhitespaceTextImpl(TinyTree tree,
                          int nodeNr)

Create a compressed whitespace text node

Parameters:

tree - the tree to contain the node

nodeNr - the internal node number

Method Detail

getStringValue

public String getStringValue()

Return the character value of the node.

Returns:

the string value of the node

See Also:

Item.getStringValueCS()

getStringValueCS

public CharSequence getStringValueCS()

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String. For a WhitespaceTextImpl node, it avoids the cost of decompressing the whitespace

Specified by:

getStringValueCS in interface Item

Specified by:

getStringValueCS in interface ValueRepresentation

Overrides:

getStringValueCS in class TinyNodeImpl

Returns:

the string value of the item

See Also:

Item.getStringValue()

getStringValueCS

public static CharSequence getStringValueCS(TinyTree tree,
                                            int nodeNr)

Static method to get the string value of a text node without first constructing the node object

Parameters:

tree - the tree

nodeNr - the node number of the text node

Returns:

the string value of the text node

appendStringValue

public static void appendStringValue(TinyTree tree,
                                     int nodeNr,
                                     FastStringBuffer buffer)

Static method to get the string value of a text node and append it to a supplied buffer without first constructing the node object

Parameters:

tree - the tree

nodeNr - the node number of the text node

buffer - a buffer to which the string value will be appended

atomize

public Value atomize()
              throws XPathException

Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.

Returns:

the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.

Throws:

XPathException

Since:

8.5

getTypedValue

public SequenceIterator getTypedValue()
                               throws XPathException

Get the typed value of the item.

For a node, this is the typed value as defined in the XPath 2.0 data model. Since a node may have a list-valued data type, the typed value is in general a sequence, and it is returned in the form of a SequenceIterator.

If the node has not been validated against a schema, the typed value will be the same as the string value, either as an instance of xs:string or as an instance of xs:untypedAtomic, depending on the node kind.

For an atomic value, this method returns an iterator over a singleton sequence containing the atomic value itself.

Returns:

an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.

Throws:

XPathException - where no typed value is available, for example in the case of an element with complex content

Since:

8.4

getLongValue

public static long getLongValue(TinyTree tree,
                                int nodeNr)

Static method to get the "long" value representing the content of a whitespace text node

Parameters:

tree - the TinyTree

nodeNr - the internal node number

Returns:

a value representing the compressed whitespace content

See Also:

CompressedWhitespace

getNodeKind

public final int getNodeKind()

Return the type of node.

Returns:

Type.TEXT

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. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.

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
