TXMLToRODL

Overview

The TXMLToRODL class is a specialization of the TRODLReader class for decoding

streamed RODL data in the XML format into a TRODLLibrary instance. You may use it to load

RODL files, resources, etc.

Use case

Take a look at this excerpt from the 'uRODL.pas' file:

function ReadRODLFromFile(aReaderClass: TRODLReaderClass; const aFileName: string): TRODLLibrary;
begin
  

with aReaderClass.Create do try
    result := ReadFromFile(aFileName);
  finally
    Free;
  end;
end;

It

may be used as

//...
var
  lib: TRODLLibrary;
begin
  lib :=  ReadRODLFromFile(TXMLToRODL, 

'...');
//...

procedure LoadFileToLibrary(iFilename: string; iLibrary: TRODLLibrary; iRodlUse: TRODLUse)

Parameters:

  • iFilename: Name of the source file
