All Implemented Interfaces:
  org.w3c.dom.CharacterData, java.lang.Cloneable, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, java.io.Serializable, org.w3c.dom.Text

Direct Known Subclasses:
  CDATASectionImpl, DeferredTextImpl

public class TextImpl
extends CharacterDataImpl
implements org.w3c.dom.CharacterData, org.w3c.dom.Text

Text nodes hold the non-markup, non-Entity content of an Element or Attribute.

When a document is first made available to the DOM, there is only one Text object for each block of adjacent plain-text. Users (ie, applications) may create multiple adjacent Texts during editing -- see `Node.normalize()` for discussion.

Note that CDATASection is a subclass of Text. This is conceptually valid, since they're really just two different ways of quoting characters when they're written out as part of an XML stream.

Constructor Detail

### TextImpl

    public TextImpl()

  Default constructor

### TextImpl

    public TextImpl(CoreDocumentImpl ownerDoc,
                    java.lang.String data)

  Factory constructor.

Method Detail

### setValues

    public void setValues(CoreDocumentImpl ownerDoc,
                          java.lang.String data)

  NON-DOM: resets node and sets specified values for the current node
  Parameters:
    `ownerDoc` -
    `data` -

### getNodeType

    public short getNodeType()

  A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.
  Specified by:
    `getNodeType` in interface `org.w3c.dom.Node`
  Overrides:
    `getNodeType` in class `NodeImpl`

### getNodeName

    public java.lang.String getNodeName()

  Returns the node name.
  Specified by:
    `getNodeName` in interface `org.w3c.dom.Node`
  Overrides:
    `getNodeName` in class `NodeImpl`

### setIgnorableWhitespace

    public void setIgnorableWhitespace(boolean ignore)

  NON-DOM: Set whether this Text is ignorable whitespace.

### isElementContentWhitespace

    public boolean isElementContentWhitespace()

  DOM L3 Core CR - Experimental Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace". The text node is determined to contain whitespace in element content during the load of the document or if validation occurs while using `Document.normalizeDocument()`.
  Since:
    DOM Level 3

### getWholeText

    public java.lang.String getWholeText()

  DOM Level 3 WD - Experimental. Returns all text of `Text` nodes logically-adjacent text nodes to this node, concatenated in document order.
  Since:
    DOM Level 3

### replaceWholeText

    public org.w3c.dom.Text replaceWholeText(java.lang.String content)
                                      throws org.w3c.dom.DOMException

  DOM Level 3 WD - Experimental.

### isIgnorableWhitespace

    public boolean isIgnorableWhitespace()

  NON-DOM: Returns whether this Text is ignorable whitespace.

### splitText

    public org.w3c.dom.Text splitText(int offset)
                               throws org.w3c.dom.DOMException

  Break a text node into two sibling nodes. (Note that if the current node has no parent, they won't wind up as "siblings" -- they'll both be orphans.)
  Specified by:
    `splitText` in interface `org.w3c.dom.Text`
  Parameters:
    `offset` - The offset at which to split. If offset is at the end of the available data, the second node will be empty.
  Returns:
    A reference to the new node (containing data after the offset point). The original node will contain data up to that point.
  Throws:
    `DOMException(INDEX_SIZE_ERR)` - if offset is <0 or >length.
    `DOMException(NO_MODIFICATION_ALLOWED_ERR)` - if node is read-only.

### replaceData

    public void replaceData(java.lang.String value)

  NON-DOM (used by DOMParser): Reset data for the node.

### removeData

    public java.lang.String removeData()

  NON-DOM (used by DOMParser: Sets data to empty string. Returns the value the data was set to.
