TDOMCharacterData class

In unit Laz2_DOM

Implements the CharacterData interface from the DOM specification.

Declaration

pascal

TDOMCharacterData = class(TDOMNode)

Inheritance

TDOMCharacterData
TDOMNode

Descends from it: TDOMComment TDOMText

Description

TDOMCharacterData is a TDOMNode descendant that implements the CharacterData interface from the DOM specification. TDOMCharacterData provides properties and methods used to access and manipulate character data in the DOM APIs.

Methods which alter character data use 0-based offsets; the offset values are converted internally to the 1-based offsets used in FPC / Lazarus.

TDOMCharacterData is the ancestor class for other DOM Node specializations like TDOMText and TDOMComment. TDOMCharacterData is not used directly. Use one of the descendent classes.

Use TDOMCDATASection for the CDATA interface defined in the DOM specification.

Properties

`Data`	public	Provides access to the character data in the NodeValue property.
`Length`	public	Length of the character data for the class instance.

Methods

`GetLength`	protected	Gets the value for the Length property.
`GetNodeValue`	protected	Gets the value for the NodeValue property.
`SetNodeValue`	protected	Sets the value for the NodeValue property.
`SubstringData`	public	Copies character data at the specified offset for the number of bytes requested.
`AppendData`	public	Appends the specified value to the end of the character data.
`InsertData`	public	Inserts the specified value at the given offset in the character data.
`DeleteData`	public	Deletes a given number of characters at the specified offset in the character data.
