- Description
- Template C++ class representing an IDL sequence. Template argument is the sequence element type. C++ Sequences are reference counted and shared, so the sequence keeps a handle to its data. To keep value semantics, copies are only generated if the sequence is to be modified (new handle).
- Template Parameters
E element type of sequence
- File
- Sequence.h
Public Members

Typedefs
ElementType typedefs the element type of the sequence
Methods
Sequence( ) throw( );Default constructor: Creates an empty sequence.
Sequence( const Sequence< E > & rSeq ) throw( );Copy constructor: Creates a copy of given sequence.
Sequence( uno_Sequence * pSequence, __sal_NoAcquire ) throw( );Constructor: Takes over ownership of given sequence.
Sequence( const E * pElements, sal_Int32 len );Constructor: Creates a copy of given elements.
Sequence( sal_Int32 len );Constructor: Creates a default constructed sequence of given length.
~Sequence( ) throw( );Destructor: Releases sequence handle. Last handle will destruct elements and free memory. Sequence< E > &
operator=( const Sequence< E > & rSeq ) throw( );Assignment operator: Acquires given sequence handle and releases previously set handle. sal_Int32
getLength( ) const throw( );Gets length of the sequence. sal_Bool
hasElements( ) const throw( );Tests whether the sequence has elements, i.e. elements count is greater than zero. const E *
getConstArray( ) const throw( );E *
getArray( );E &
operator[]( sal_Int32 nIndex );const E &
operator[]( sal_Int32 nIndex ) const throw( );Const index operator: Obtains a reference to element indexed at given position. The implementation does not check for array bounds! sal_Bool
operator==( const Sequence< E > & rSeq ) const throw( );Equality operator: Compares two sequences. sal_Bool
operator!=( const Sequence< E > & rSeq ) const throw( );Unequality operator: Compares two sequences. void
realloc( sal_Int32 nSize );uno_Sequence *
get( ) const throw( );Provides UNacquired sequence handle.
