## Class TextImpl

- java.lang.Object
- - org.apache.xerces.dom.NodeImpl
  - - org.apache.xerces.dom.ChildNode
    - - org.apache.xerces.dom.CharacterDataImpl
      - - org.apache.xerces.dom.TextImpl

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

      Specified by:
        `replaceWholeText` in interface `org.w3c.dom.Text`
      Parameters:
        `content` - The content of the replacing Text node.
      Returns:
        text - The Text node created with the specified content.
      Throws:
        `org.w3c.dom.DOMException` - NO_MODIFICATION_ALLOWED_ERR: Raised if one of the `Text` nodes being replaced is readonly.
      Since:
        DOM Level 3

          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.
        `org.w3c.dom.DOMException` - INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in `data`.
        NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    - #### replaceData

          public void replaceData(java.lang.String value)

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

    - #### removeData

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