Detailed Description

template<class T, class T_slice>
class TAO_Unbounded_Array_Sequence< T, T_slice >

Parametric sequence for arrays.

The IDL mapping for arrays includes some unique allocation, deallocation, and copying functions, and precludes direct assignment of one array to another. Also, the Any and CDR operators use a special class derived from the array. For these reasons, we use a special class for sequences of arrays.

Member Function Documentation

template<typename T, typename T_slice>
void TAO_Unbounded_Array_Sequence< T, T_slice >::_allocate_buffer CORBA::ULong    length [virtual]
 

allocate a buffer of the requested length. The buffer is allocated for the right type

Implements TAO_Base_Sequence.

template<typename T, typename T_slice>
void TAO_Unbounded_Array_Sequence< T, T_slice >::_deallocate_buffer void    [virtual]
 

deallocate the buffer

Implements TAO_Base_Sequence.

template<typename T, typename T_slice>
T * TAO_Unbounded_Array_Sequence< T, T_slice >::allocbuf CORBA::ULong    [static]
 

The allocbuf function allocates a vector of T elements that can be passed to the T *data constructor.

template<typename T, typename T_slice>
ACE_INLINE void TAO_Unbounded_Array_Sequence< T, T_slice >::freebuf T *    [static]
 

Release all the elements.

template<typename T, typename T_slice>
ACE_INLINE const T * TAO_Unbounded_Array_Sequence< T, T_slice >::get_buffer void    const
 

This function allows read-only access to the sequence buffer. The sequence returns its buffer, allocating one of one has not yet been allocated. No direct modification of the returned buffer by the caller is permitted.

template<typename T, typename T_slice>
T * TAO_Unbounded_Array_Sequence< T, T_slice >::get_buffer CORBA::Boolean    orphan = 0
 

Allows read-write access to the underlying buffer. If <orphan> is FALSE the sequence returns a pointer to its buffer, allocating one if it has not yet done so. The number of elements in the buffer can be determined from the sequence <length> accessor.

If the <orphan> argument to <get_buffer> is FALSE, the sequence maintains ownership of the underlying buffer. Elements in the returned buffer may be directly replaced by the caller.

If the <orphan> argument to <get_buffer> is TRUE, the sequence yields ownership of the buffer to the caller. If <orphan> is TRUE and the sequence does not own its buffer (i.e., its <release> flag is FALSE), the return value is a null pointer. If the buffer is taken from the sequence using this form of <get_buffer>, the sequence reverts to the same state it would have if constructed using its default constructor. The caller becomes responsible for eventually freeing each element of the returned buffer (for strings, wide string, and object references), and then freeing the returned buffer itself using <freebuf>.

template<typename T, typename T_slice>
TAO_Unbounded_Array_Sequence< T, T_slice > & TAO_Unbounded_Array_Sequence< T, T_slice >::operator= const TAO_Unbounded_Array_Sequence< T, T_slice > &   
 

The assignment operator first releases all object reference members and frees all string members, and then performs a deepcopy to create a new structure.

ACE_INLINE const T & TAO_Unbounded_Array_Sequence< T, T_slice >::operator[] CORBA::ULong    const

void TAO_Unbounded_Array_Sequence< T, T_slice >::replace CORBA::ULong    max,
CORBA::ULong    length,
T *    data,
CORBA::Boolean    release = 0
 

Allows the buffer underlying a sequence to be replaced. The parameters to <replace> are identical in type, order, and purpose to those for the <T *data> constructor for the sequence.
