CharacterData is an abstract Node that can carry character data as its Value. It provides shared behavior for Text, CData, and possibly other node types. All offsets are 0-based.
Since ProcessingInstructionImpl inherits from this class to reuse the setNodeValue method, this class isn't declared as implementing the interface CharacterData. This is done by relevant subclasses (TexImpl, CommentImpl).
This class doesn't directly support mutation events, however, it notifies the document when mutations are performed so that the document class do so.
This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

String data)
Deprecated. Replace a series of characters at the specified (zero-based) offset with a new string, NOT necessarily of the same length. |

void |
setNodeValue(String value)
Deprecated. Sets the content, possibly firing related events, and updating ranges (via notification to the document) |

DOMException
public void replaceData(int offset, int count, String data) throws DOMException
offset
- The offset at which to begin replacing.count
- The number of characters to remove,
interpreted as in the delete() method.data
- The new string to be inserted at offset in place of
the removed data. Note that the entire string will
be inserted -- the count parameter does not affect
insertion, and the new data may be longer or shorter
than the substring it replaces.
DOMException(INDEX_SIZE_ERR)
- if offset is negative or
greater than length, or if count is negative.
DOMException(NO_MODIFICATION_ALLOWED_ERR)
- if node is
readonly.

This is important, because we do one type of Range fix-up, from the high-level functions in CharacterData, and another type if the client simply calls setNodeValue(value).
public String substringData(int offset, int count) throws DOMException
offset
- Zero-based offset of first character to retrieve.count
- Number of characters to retrieve.
If the sum of offset and count exceeds the length, all characters
to end of data are returned.
DOMException(INDEX_SIZE_ERR)
- if offset is negative or
greater than length, or if count is negative.
DOMException(WSTRING_SIZE_ERR)
- In some implementations,
count may exceed the permitted length of strings. If so,
substring() will throw this DOMException advising the user to
instead retrieve the data in smaller chunks.
