DefineProperty public Defines data the reader object reads as if it were a published property.
Destroy public Moves the current position of the stream back to the beginning before calling the inherited destructor.
Dispatch public Calls message-handling methods for the object, based on the contents of the Message parameter.
EndOfList public Indicates the end of a group of items that are sequentially read from the stream.

Free public Destroys an object and frees its associated memory, if necessary.
FreeInstance public Deallocates memory allocated by a previous call to the NewInstance method.
GetDisposed protected Getter for the Disposed property.
GetHashCode public Returns an integer containing the hash code.
GetInterface public Retrieves a specified interface.
GetInterfaceEntry public Returns the entry for a specific interface implemented in a class.
GetInterfaceTable public Returns a pointer to a structure containing all of the interfaces implemented by a given class.
InheritsFrom public Determines the relationship of two object types.
InitInstance public Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
InstanceSize public Returns the size in bytes of each instance of the object type.
MethodAddress public Returns the address of a class method by name.
MethodName public Returns the name of a class method by address.
NewInstance public Allocates memory for an instance of an object type and returns a pointer to that new instance.
NextValue public Reads and returns the value-type indicator of the next item in the reader object's stream without moving the stream position.
PropertyError protected
QualifiedClassName public Returns the qualified name of the class.
ReadBoolean public Reads a boolean value-type indicator from the reader object's stream and returns the corresponding boolean value.
ReadChar public Reads and returns a character from the reader object's stream.
ReadCollection public Reads all collection items of the specified
Collection at the reader object's stream. ReadComponent public Reads the specified
Component at the current Position of the reader stream and returns the retrieved component. ReadComponents public Reads a list of owned components from the reader object's associated stream.
ReadCurrency public Reads and returns a Currency type value from the reader object's stream.
ReadData protected
ReadDouble public Reads and returns a Double floating-point number from the reader object's stream.
ReadFloat public Reads and returns an Extended floating-point number from the reader object's stream.
ReadInt64 public Reads and returns a 64-bit integer from the reader object's stream.
ReadInteger public Reads and returns an integer type number from the reader object's stream.
ReadListBegin public Reads a start-of-list value-type indicator from the reader object's stream.
ReadListEnd public Reads an end-of-list value-type indicator from the reader object's stream.
ReadPrefix public Reads preliminary information concerning form inheritance for a component.
ReadProperty protected
ReadPropValue protected
ReadRootComponent public Reads a component and all its owned components from the reader object's stream.
ReadSet protected
ReadSignature public Reads the filer signature from the reader object's associated stream.
ReadSingle public Reads and returns a Single floating-point number from the reader object's stream.
ReadStr public Reads and returns a UTF8 format string from the reader object's stream.
ReadString public Reads and returns a string from the reader object's stream.
ReadValue public Reads and returns the value-type indicator of the next item on the reader object's stream and advances the stream position after the value-type indicator.
ReadVar public Methods responsible for reading up to
Count bytes from the internal reader object's buffer into the specified typed Buffer parameter. ReadVariant public Reads and returns a Variant type value from the reader object's stream.
ReadWideChar (deprecated) public Reads a wide character from the reader object's stream and returns that character value.
ReadWideString (deprecated) public Reads a tagged wide string value from the reader object's stream and returns its contents.
