Public Member Functions | |
| wxMemoryOutputStream (void *data=NULL, size_t length=0) | |
| If data is NULL, then it will initialize a new empty buffer which will grow if required. More... | |
| virtual | ~wxMemoryOutputStream () |
| Destructor. More... | |
| size_t | CopyTo (void *buffer, size_t len) const |
| Allows you to transfer data from the internal buffer of wxMemoryOutputStream to an external buffer. More... | |
| wxStreamBuffer * | GetOutputStreamBuffer () const |
| Returns the pointer to the stream object used as an internal buffer for this stream. More... | |
Public Member Functions inherited from wxOutputStream | |
| wxOutputStream () | |
| Creates a dummy wxOutputStream object. More... | |
| virtual | ~wxOutputStream () |
| Destructor. More... | |
| virtual bool | Close () |
| Closes the stream, returning false if an error occurs. More... | |
| virtual size_t | LastWrite () const |
| Returns the number of bytes written during the last Write(). More... | |
| void | PutC (char c) |
| Puts the specified character in the output queue and increments the stream position. More... | |
| virtual wxFileOffset | SeekO (wxFileOffset pos, wxSeekMode mode=wxFromStart) |
| Changes the stream current position. More... | |
| virtual wxFileOffset | TellO () const |
| Returns the current stream position. More... | |
| virtual wxOutputStream & | Write (const void *buffer, size_t size) |
| Writes up to the specified amount of bytes using the data of buffer. More... | |
| wxOutputStream & | Write (wxInputStream &stream_in) |
| Reads data from the specified input stream and stores them in the current stream. More... | |
| bool | WriteAll (const void *buffer, size_t size) |
| Writes exactly the specified number of bytes from the buffer. More... | |
Public Member Functions inherited from wxStreamBase | |
| wxStreamBase () | |
| Creates a dummy stream object. More... | |
| virtual | ~wxStreamBase () |
| Destructor. More... | |
| wxStreamError | GetLastError () const |
| This function returns the last error. More... | |
| virtual wxFileOffset | GetLength () const |
| Returns the length of the stream in bytes. More... | |
| virtual size_t | GetSize () const |
| This function returns the size of the stream. More... | |
| virtual bool | IsOk () const |
| Returns true if no error occurred on the stream. More... | |
| virtual bool | IsSeekable () const |
| Returns true if the stream supports seeking to arbitrary offsets. More... | |
| void | Reset (wxStreamError error=wxSTREAM_NO_ERROR) |
| Resets the stream state. More... | |
| bool | operator! () const |
| Returns the opposite of IsOk(). More... | |

| wxMemoryOutputStream::wxMemoryOutputStream | ( | void * | data = NULL, |
| size_t | length = 0 |
||
| ) |
If data is NULL, then it will initialize a new empty buffer which will grow if required.
|
virtual |
Destructor.
If the buffer wasn't provided by the user, it will be deleted here.
| size_t wxMemoryOutputStream::CopyTo | ( | void * | buffer, |
| size_t | len | ||
| ) | const |
Allows you to transfer data from the internal buffer of wxMemoryOutputStream to an external buffer.
len specifies the size of the buffer.
| wxStreamBuffer* wxMemoryOutputStream::GetOutputStreamBuffer | ( | ) | const |
Returns the pointer to the stream object used as an internal buffer for this stream.
