Detailed Description

template<class T>
class d_Varray< T >

It's a container class (see Containers), it's ordered by index and allows duplicates.

This class is like the vector of the C++ Library, but is persistent.

LOCATION: d_Varray.h

USAGE: d_Varray< <type-name> > <property-name>;

Where:

<type-name>: Type to contain. Can be a literal or a user type <PROPERTY-NAME>: NAME OF PROPERTY

EXAMPLES: class Invoice : public d_Object { * Relationship 1-n to product objects d_Varray< d_Ref<Product> > products; };

d_Ref<Invoice> myInvoice; * Ref to Invoice object

SEE ALSO: d_Bag, d_Collection, d_Dictionary, d_Iterator, d_List, d_Set

ODMG: Compliant

Member Function Documentation

template<class T> virtual d_Boolean d_Varray< T >::allows_duplicates (    )  const [virtual]

Returns always true. ODMG : Compliant Implements d_Collection< T >.

template<class T> d_Boolean d_Varray< T >::find_element (  const T &    iValue, d_ULong &    ioPosition )

Search the value in the container. Search the value in the array. If the element is found its position is returned in and the method returns true; otherwise it returns false. ODMG : Compliant

template<class T> virtual d_Boolean d_Varray< T >::is_ordered (    )  const [virtual]

Returns always true. ODMG : Compliant Implements d_Collection< T >.

template<class T> T d_Varray< T >::operator[] (  const oUInt4    iIndex )

Returns the value at any position. Returns the value at position . If is out of the range, an exception d_Error_PositionOutOfRange is raised. This method permits to handle a d_Varray object as a common C++ array. SEE ALSO: retrieve_element_at() ODMG : Compliant

template<class T> void d_Varray< T >::remove_element_at (  const d_ULong    iPosition )

Remove an element. Remove the element at position . If is out of the range, an exception d_Error_PositionOutOfRange is raised. SEE ALSO: remove_all(), d_Iterator::remove_element () ODMG : Compliant

template<class T> void d_Varray< T >::replace_element_at (  const T &    iValue, const d_ULong    iPosition )

Replace an element. Replace the element at position with . If is out of the range, an exception d_Error_PositionOutOfRange is raised. SEE ALSO: d_Iterator::replace_element () ODMG : Compliant

template<class T> T d_Varray< T >::retrieve_element_at (  const d_ULong    iIndex )

Returns the value at any position. Returns the value at position . If is out of the range, an exception d_Error_PositionOutOfRange is raised. SEE ALSO: operator[]() ODMG : Compliant
