org.kde.koala.CharacterData
public class CharacterData
The CharacterData
interface extends Node with a set
of attributes and methods for accessing character data in the DOM.
For clarity this set is defined here rather than on each object
that uses these attributes and methods. No DOM objects correspond
directly to CharacterData
, though Text
and others do inherit the interface from it. All
offset
s in this interface start from 0.

public java.lang.String data()
CharacterData
node. However, implementation limits may mean that the
entirety of a node's data may not fit into a single
DOMString
. In such cases, the user may call
substringData
to retrieve the data in appropriately
sized pieces.
public void setData(java.lang.String arg1)
public long length()
data
and the substringData
method below. This
may have the value zero, i.e., CharacterData
nodes may be empty.
public java.lang.String substringData(long offset, long count)
offset
- Start offset of substring to extract.count
- The number of characters to extract.
DOMSTRING_SIZE_ERR: Raised if the specified range of text does
not fit into a DOMString
.
offset
and count
exceeds the length
, then all characters to the end of the data are
returned.public void appendData(java.lang.String arg)
data
provides access to the
concatenation of data
and the DOMString
specified.
arg
- The DOMString
to append.public void insertData(long offset, java.lang.String arg)
offset
- The character offset at which to insert.arg
- The DOMString
to insert.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.public void deleteData(long offset, long count)
data
and length
reflect the
change.
offset
- The offset from which to remove characters.count
- The number of characters to delete. If the sum of
offset
and count
exceeds
length
then all characters from offset
to the end of the data are deleted.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.public void replaceData(long offset, long count, java.lang.String arg)
offset
- The offset from which to start replacing.count
- The number of characters to replace. If the sum of
offset
and count
exceeds
length
, then all characters to the end of the data are
replaced (i.e., the effect is the same as a remove
method call with the same range, followed by an
append
method invocation).arg
- The DOMString
with which the range
must be replaced.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
