nu.xom.Text

public class Text
extends Node

This class represents a run of text. CDATA sections are not treated differently than normal text. Text objects may be adjacent to other Text objects.

The maximum size of a String or an array in Java limits the maximum size of a text node to about 2 gigabytes. If you're stuffing Base-64 encoded movies inside one node, you will have problems. Try breaking up the text into smaller, contiguous chunks. Even then you will probably not be able to use XPath on the result.

Constructor Detail

Text

public Text(String data)

This constructor creates a new Text object. The data is checked for legality according to XML 1.0 rules. Characters that can be serialized by escaping them such as < and & are allowed. However, characters such as the form feed, null, vertical tab, unmatched halves of surrogate pairs, and 0xFFFE and 0xFFFF are not allowed.

Parameters:

data - the initial text of the object

Throws:

IllegalCharacterDataException - if data contains any characters which are illegal in well-formed XML 1.0 such as null, vertical tab, or unmatched halves of surrogate pairs

Text

public Text(Text text)

Creates a copy of the specified Text object.

Parameters:

text - the Text object to copy

Method Detail

setValue

public void setValue(String data)

Sets the content of the Text object to the specified data. The data is checked for legality according to XML 1.0 rules. Characters that can be serialized such as < and & are allowed. However, characters such as the form feed, null, vertical tab, unmatched halves of surrogate pairs, and 0xFFFE and 0xFFFF are not allowed. Passing null is the same as passing the empty string.

Parameters:

data - the text to install in the object

Throws:

IllegalCharacterDataException - if data contains any characters which are illegal in well-formed XML 1.0 such as null, vertical tab, or unmatched halves of surrogate pairs

getValue

public final String getValue()

Returns the XPath 1.0 string-value of this Text node. The XPath string-value of a text node is the same as the text of the node.

Specified by:

getValue in class Node

Returns:

the content of the node

getChild

public final Node getChild(int position)

Throws IndexOutOfBoundsException because texts do not have children.

Specified by:

getChild in class Node

Parameters:

position - the index of the child node to return

Returns:

never returns because texts do not have children; always throws an exception.

Throws:

IndexOutOfBoundsException - because texts do not have children

getChildCount

public final int getChildCount()

Returns 0 because texts do not have children.

Specified by:

getChildCount in class Node

Returns:

zero

copy

public Text copy()

Returns a deep copy of this Text with no parent, that can be added to this document or a different one.

Specified by:

copy in class Node

Returns:

a deep copy of this text node with no parent

toXML

public final String toXML()

Returns a string containing the XML serialization of this text node. Unlike getValue, this method escapes characters such as & and < using entity references such as & and <. It escapes the carriage return (\r) as 
. If this text node is a CDATA section, then it may wrap the value in CDATA section delimiters instead of escaping.

Specified by:

toXML in class Node

Returns:

the string form of this text node

toString

public final String toString()

Returns a String representation of this Text suitable for debugging and diagnosis. This is not the XML representation of this Text node.

Overrides:

toString in class Object

Returns:

a non-XML string representation of this node
