Protected Member Functions | |
WvBufStore (int _granularity) | |
Creates a new buffer. | |
virtual bool | usessubbuffers () const |
Returns true if the buffer uses subbuffers for storage. | |
virtual size_t | numsubbuffers () const |
Returns the number of subbuffers in the buffer. | |
virtual WvBufStore * | firstsubbuffer () const |
Returns the first subbuffer. | |
virtual void | appendsubbuffer (WvBufStore *buffer, bool autofree) |
Appends a subbuffer to the buffer. | |
virtual void | prependsubbuffer (WvBufStore *buffer, bool autofree) |
Prepends a subbuffer to the buffer. | |
virtual bool | unlinksubbuffer (WvBufStore *buffer, bool allowautofree) |
Unlinks the specified subbuffer. | |
Protected Attributes | |
int | granularity |
WvBufStore::WvBufStore | ( | int | _granularity | ) | [explicit, protected] |
Creates a new buffer.
"_granularity" is the suggested granularity for data allocation and alignment purposes

virtual WvBufStore* WvBufStore::firstsubbuffer | ( | ) | const [inline, protected, virtual] |
Returns the first subbuffer.
Returns: the buffer or NULL if none or not supported

virtual bool WvBufStore::unlinksubbuffer | ( | WvBufStore * | buffer, | |
bool | allowautofree | |||
) | [inline, protected, virtual] |
Unlinks the specified subbuffer.
Only autofrees the buffer if allowautofree == true. Returns: the autofree flag for the buffer
