In unit Laz2_XMLCfg

Implements an XML configuration file with RTTI support.

Declaration

pascal

TRttiXMLConfig = class(TXMLConfig)

Inheritance

Description

TRttiXMLConfig is a TXMLConfig descendant which implements support for reading and writing objects and their property values using RTTI (Run-Time Type Information). TRttiXMLConfig extends the ancestor class to include methods used to read and write objects, or just specific properties, using path specifiers supported in the class. See the TXMLConfig Path Syntax topic for more information about path specifiers in TXMLConfig.

Type information provided by RTTI (Run-Time Type Information) is used to determine the value and formatting used for supported data types. Supported RTTI type kinds include:

tkChar
tkWChar
tkSString
tkLString
tkAString
tkInteger
tkFloat
tkEnumeration
tkSet
tkBool
tkClass

Properties must be implemented with both getter and setter procedures to be available for use in TRttiXMLConfig. Properties which do not use both types of procedure are ignored.
