Main page -> Midware component reference -> TMWBuffer -> Sort
Definition
procedure Sort(BuildKey:TMWBufferSortBuildKey;Ascending:Boolean);
Description
Sort will sort TMWBuffer content. Sort is based on keys. Keys are built by an external function passed as BuildKey argument. Sort will scan all records, calling BuildKey to build an array of keys. The array is sorted and TMWBuffer data reorganized accordingly.
If BuildKey is nil, then a default function is used instead. This default function use first fireld as key.
Example
<syntaxhighlight lang="delphi"> procedure TForm1.Button1Click(Sender: TObject); begin
MWBuffer1.Sort(MyBuildKeyFunction, TRUE);
end;
function MyBuildKeyFunction(MWBuffer : TMWBuffer) : String; begin
Result := MWBuffer.Fields[0] + ' ' +
MWBuffer.Fields[1];
end; </syntaxhighlight>
