DefinePropertypublicDefines data the reader object reads as if it were a published property.
DestroypublicMoves the current position of the stream back to the beginning before calling the inherited destructor.
DispatchpublicCalls message-handling methods for the object, based on the contents of the Message parameter.
DisposeOfpublicDisposeOf forces the execution of the destructor code in an object.

MethodNamepublicReturns the name of a class method by address.
NewInstancepublicAllocates memory for an instance of an object type and returns a pointer to that new instance.

ReadDataprotected
ReadDatepublicReads a TDateTime value from the reader object's stream and returns its value.
ReadDoublepublicReads a double type floating point number from the reader object's stream and returns its value.
ReadFloatpublicReads a floating-point number from the reader object's stream and returns its value.
ReadIdentpublicReads an identifier from the reader object's stream and returns the identifier.
ReadInt64publicReads an 64-bit integer from the reader object's stream and returns its value.
ReadIntegerpublicReads an integer-type number from the reader object's stream and returns its value.
ReadListBeginpublicReads a start-of-list marker from the reader object's associated stream.
ReadListEndpublicReads an end-of-list marker from the reader object's associated stream.
ReadPrefixpublicReads preliminary information concerning form inheritance for a component.
