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:

Serializable, Cloneable, CharacterData, EventTarget, Node, NodeList, Text

Direct Known Subclasses:

CDATASectionImpl, DeferredTextImpl

public class TextImpl
extends CharacterDataImpl
implements CharacterData, 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.

Since:

PR-DOM-Level-1-19980818.

Constructor Detail

TextImpl

public TextImpl()

Default constructor

TextImpl

public TextImpl(CoreDocumentImpl ownerDoc,
                String data)

Factory constructor.

Method Detail

setValues

public void setValues(CoreDocumentImpl ownerDoc,
                      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 Node

Specified by:

getNodeType in class NodeImpl

getNodeName

public String getNodeName()

Returns the node name.

Specified by:

getNodeName in interface Node

Specified by:

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().

Specified by:

isElementContentWhitespace in interface Text

Since:

DOM Level 3

getWholeText

public String getWholeText()

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

Specified by:

getWholeText in interface Text

Since:

DOM Level 3

insertTextContent

protected void insertTextContent(StringBuffer buf)
                          throws DOMException

internal method taking a StringBuffer in parameter and inserts the text content at the start of the buffer

Parameters:

buf -

Throws:

DOMException

replaceWholeText

public Text replaceWholeText(String content)
                      throws DOMException

Replaces the text of the current node and all logically-adjacent text nodes with the specified text. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.

Specified by:

replaceWholeText in interface Text

Parameters:

content - The content of the replacing Text node.

Returns:

text - The Text node created with the specified content.

Throws:

DOMException

Since:

DOM Level 3

isIgnorableWhitespace

public boolean isIgnorableWhitespace()

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

splitText

public Text splitText(int offset)
               throws 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 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.

DOMException

replaceData

public void replaceData(String value)

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

removeData

public String removeData()

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