All content below this line refers to {{#multireplace:Data.DB.TDataSet.GetBookmarkData|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Gets the bookmark for the record buffer given by the parameter.
GetBookmarkData is used to get the bookmark for the Buffer record buffer. The Data parameter is a pointer to the bookmark of the Buffer record.
The method is virtual. Every TDataSet descendant must implement it in a specific way. A record buffer stores the data of the record, the bookmark, and the bookmark flags.
Note: Unidirectional datasets do not use bookmarks.
