public abstract class CharacterDataImpl extends LeafNodeImpl implements CharacterData
Some of the fields may have package visibility, so other classes belonging to the DOM implementation can easily access them while maintaining the DOM tree structure.

CharacterDatadata and length reflect the change.deleteData in interface CharacterDataoffset - The offset from which to start removing.count - The number of 16-bit units to delete. If the sum of
offset and count exceeds
length then all 16-bit units from offset

negative or greater than the number of 16-bit units in

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.getData in interface CharacterDataDOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than
