class Sequence


Base Classes
None.
Known Derived Classes
None.

virtual abstract interface template
NO NO NO YES
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.
explicit
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.
