Class Text

    Object
      nu.xom.Node
          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.

Version:
  1.1b3
Author:
  Elliotte Rusty Harold

Constructor Summary
`Text(String data)` This constructor creates a new `Text` object.
`Text(Text text)` Creates a copy of the specified `Text` object.

Method Summary
`Node` | `copy()` Returns a deep copy of this `Text` with no parent, that can be added to this document or a different one.
`Node` | `getChild(int position)` Throws `IndexOutOfBoundsException` because texts do not have children.
`int` | `getChildCount()` Returns 0 because texts do not have children.
`String` | `getValue()` Returns the XPath 1.0 string-value of this `Text` node.
`void` | `setValue(String data)` Sets the content of the `Text` object to the specified data.
`String` | `toString()` Returns a `String` representation of this `Text` suitable for debugging and diagnosis.
`String` | `toXML()` Returns a string containing the XML serialization of this text node.

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 Node 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 `&amp;` and `&lt;`. It escapes the carriage return (\r) as `&#x0D;`. 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
