RefAny Class

The RefAny class is designed to support a reference to any type. Its primary purpose is to handle generic references and allow conversions of Ref in the type hierarchy. A RefAny object can be used as an intermediary between any two types, Ref<x> and Ref<y>, where x and y are different types.

RefAny()

A Ref<T> can always be converted to a RefAny; there is a method to perform the conversion in the Ref<T> template. Each Ref<T> has a constructor and assignment operator that takes a reference to RefAny.

RefAny();

RefAny(
   const Connection *sessptr,
   const OCIRef *ref);

RefAny(
   const RefAny& src);

sessptr

ref

src

clear()

This method clears the reference.

LNCPP21442Syntax

void clear();

getConnection()

Returns the connection from which this reference was instantiated.

LNCPP21444Syntax

const Connection* getConnection() const;

isNull()

Returns TRUE if the object pointed to by this ref is NULL else FALSE.

LNCPP21446Syntax

bool isNull() const;

markDelete()

This method marks the referred object as deleted.

LNCPP21448Syntax

void markDelete();

operator=()

Assignment operator for RefAny.

LNCPP21450Syntax

RefAny& operator=(
   const RefAny& src);

src

operator==()

Compares this ref with a RefAny object and returns TRUE if both the refs are referring to the same object in the cache, otherwise it returns FALSE.

LNCPP21452Syntax

bool operator== (
   const RefAny &refAnyR) const;

refAnyR

operator!=()

Compares this ref with the RefAny object and returns TRUE if both the refs are not referring to the same object in the cache, otherwise it returns FALSE.

LNCPP21454Syntax

bool operator!= (
   const RefAny &refAnyR) const;

refAnyR

unmarkDelete()

This method unmarks the referred object as dirty.

LNCPP21456Syntax

void unmarkDelete();
