Name
CharacterData
Synopsis
This interface is a generic one that is
extended by Text
, CDATASection
(which extends Text
) and
Comment
. Any node in a document tree that
implements CharacterData
also implements one of
these more specific types. This interface exists simply to group the
string manipulation methods that these text-related node types all
share.
The CharacterData
interface defines a mutable
string. getData( )
returns the
“character data” as a
String
object, and setData( )
allows it to be set from a String
object.
getLength( )
returns the number of characters of
character data, and substringData( )
returns just
the specified portion of the data as a string. The
appendData( )
, deleteData( )
,
insertData( )
, and replaceData(
)
methods mutate the data by appending a string to the end,
deleting region, inserting a string at the specified location, and
replacing a region with a specified string.
