- Description
- C++ class representing a SAL byte sequence. 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).

__ByteSequence_NoDefault __ByteSequence_NoAcquire
Methods
ByteSequence( ) throw( );Default constructor: Creates an empty sequence.
ByteSequence( const ByteSequence & rSeq ) throw( );Copy constructor: Creates a copy of given sequence.
ByteSequence( sal_Sequence * pSequence ) throw( );Copy constructor Creates a copy from the C-Handle.
ByteSequence( const sal_Int8 * pElements, sal_Int32 len );Constructor: Creates a copy of given data bytes.
ByteSequence( sal_Int32 len );Constructor: Creates sequence of given length and initializes all bytes to 0.
ByteSequence( sal_Int32 len, __ByteSequence_NoDefault nodefault );Constructor: Creates sequence of given length and does NOT initialize data. Use this ctor for performance optimization only.
ByteSequence( sal_Sequence * pSequence, __ByteSequence_NoAcquire noacquire ) throw( );
~ByteSequence( ) throw( );Destructor: Releases sequence handle. Last handle will free memory. ByteSequence &
operator=( const ByteSequence & rSeq ) throw( );Assignment operator: Acquires given sequence handle and releases a previously set handle. sal_Int32
getLength( ) const throw( );Gets the length of sequence. const sal_Int8 *
getConstArray( ) const throw( );Gets a pointer to byte array for READING. If the sequence has a length of 0, then the returned pointer is undefined. sal_Int8 *
getArray( );sal_Int8 &
operator[]( sal_Int32 nIndex );const sal_Int8 &
operator[]( sal_Int32 nIndex ) const throw( );Const index operator: Obtains a reference to byte indexed at given position. The implementation does NOT check for array bounds! sal_Bool
operator==( const ByteSequence & rSeq ) const throw( );Equality operator: Compares two sequences. sal_Bool
operator!=( const ByteSequence & rSeq ) const throw( );Unequality operator: Compares two sequences. void
realloc( sal_Int32 nSize );sal_Sequence *
getHandle( ) const throw( );Returns the UNnacquired C handle of the sequence sal_Sequence *
get( ) const throw( );Returns the UNnacquired C handle of the sequence (for compatibility reasons)
