TPersistent is the ancestor for all objects that have assignment and streaming capabilities.
TPersistent = class(TObject);
class TPersistent : public TObject;
Classes
TPersistent encapsulates the behavior common to all objects that can be assigned to other objects, and that can read and write their properties to and from a form file (.xfm or .dfm file). For this purpose TPersistent introduces methods that can be overridden to:
Define the procedure for loading and storing unpublished data to a stream.
Provide the means to assign values to properties.
Provide the means to assign the contents of one object to another.
Do not create instances of TPersistent. Use TPersistent as a base class when declaring objects that are not components, but that need to be saved to a stream or have their properties assigned to other objects.
