Constructor & Destructor Documentation

skStringBuffer::skStringBuffer (  USize  capacity, USize  growth_increment = 16 )  [inline]

Constructs a blank buffer of the given capacity. The buffer's length will be zero. Parameters: capacity  - the capacity of the buffer to create. This can be zero growth_increment  - the minimum amount to grow the buffer by if it is enlarged

Member Function Documentation

IMPORT_C void skStringBuffer::append (  const TDesC &  s  )

Adds a string to the buffer, growing it if necessary. Remarks: only available in Symbian version Parameters: s  - the string to append to the end of the current buffer Exceptions: Symbian  - a leaving function

IMPORT_C void skStringBuffer::append (  const Char *  s  )

Adds a string to the buffer, growing it if necessary. Parameters: s  - the string to append to the end of the current buffer Exceptions: Symbian  - a leaving function

IMPORT_C void skStringBuffer::append (  const skString &  s  )

Adds a string to the buffer, growing it if necessary. Parameters: s  - the string to append to the end of the current buffer Exceptions: Symbian  - a leaving function

IMPORT_C void skStringBuffer::append (  Char  ch  )

Adds a character to the buffer, growing it if necessary. Parameters: ch  - the character to add Exceptions: Symbian  - a leaving function

USize skStringBuffer::capacity (   )  const [inline]

Returns the current capacity the buffer. Returns: the capacity of the buffer

USize skStringBuffer::length (   )  const [inline]

Returns the current length of the text in the buffer. Returns: the length of the text in the buffer

IMPORT_C skStringBuffer& skStringBuffer::operator= (  const skStringBuffer &  s  )

Assignment operator - it takes a copy of the underlying buffer. Parameters: s  - the other string buffer. A copy is taken of its underlying buffer Exceptions: Symbian  - a leaving function

TPtrC skStringBuffer::ptr (   )  const [inline]

Accesses underlying buffer. Remarks: only available in Symbian version Returns: a pointer to the buffer contained within the StringBuffer object

IMPORT_C skString skStringBuffer::toString (   )

Creates a new string that owns the underlying buffer. The current buffer is set to null. Returns: a string which owns the current buffer Exceptions: Symbian  - a leaving function

IMPORT_C skString skStringBuffer::toStringCopy (   )  const

Creates a new string that copies the underlying buffer. The current buffer remains the same Returns: a string which copies the current buffer Exceptions: Symbian  - a leaving function
