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()

getStringValue

public static CharSequence getStringValue(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

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

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
