dynbuf Class Reference

Inherits databuf.

List of all members.

Detailed Description

A dynamically allocated, reference-counted mutable data buffer.

Constructing a dynbuf object allocates a fixed amount of memory, which is automatically deallocated when the last dynbuf pointing to that memory is deleted.

Note that a dynbuf may be cast to a databuf or a constbuf, but not vice versa. Also, copying a dynbuf to a databuf or constbuf does not create another reference to the underlying data.

Public Methods
	dynbuf ()
	Null constructor.
	dynbuf (unsigned int maxlen)
	Dynamically allocates a data buffer whose current length is 0 bytes but whose maximum length is maxlen bytes.
	dynbuf (const dynbuf &other)
	Copies a dynbuf, making another reference to other's underlying storage.
dynbuf &	operator= (const dynbuf &other)
	Copies a dynbuf, making another reference to other's underlying storage.
	~dynbuf ()
	Deletes the underlying storage of this dynbuf if it is the last existing copy.

Constructor & Destructor Documentation

dynbuf::dynbuf (    )

Null constructor.

dynbuf::dynbuf (  unsigned int    maxlen )

Dynamically allocates a data buffer whose current length is 0 bytes but whose maximum length is maxlen bytes. The underlying storage will be deallocate when the last dynbuf referring to that storage is destructed.

dynbuf::dynbuf (  const dynbuf &    other )

Copies a dynbuf, making another reference to other's underlying storage.

dynbuf::~dynbuf (    )

Deletes the underlying storage of this dynbuf if it is the last existing copy.

Member Function Documentation

dynbuf& dynbuf::operator= (  const dynbuf &    other )
