You can create a similar stream by this way:
|
|
|
|
\begin{verbatim}
|
|
wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::read);
|
|
wxInputStream *input = new wxInputStream(sb);
|
|
|
|
sb->SetBufferIO(data, data\_end);
|
|
\end{verbatim}

\membersection{wxMemoryInputStream::wxMemoryInputStream}
|
|
|
|
\func{}{wxMemoryInputStream}{\param{const char *}{ data}, \param{size\_t}{ len}}
|
|
|
|
Initializes a new read-only memory stream which will use the specified buffer
|
|
\it{data} of length \it{len}.
|
|
|
|
\membersection{wxMemoryInputStream::\destruct{wxMemoryInputStream}}
|
|
|
|
\func{}{\destruct{wxFileInputStream}}{\void}
|
|
|
|
Destructor.

You can create a similar stream by this way:
|
|
|
|
\begin{verbatim}
|
|
wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::write);
|
|
wxOutputStream *input = new wxOutputStream(sb);
|
|
|
|
// If there are data
|
|
sb->SetBufferIO(data, data\_end);
|
|
// Else
|
|
sb->Fixed(FALSE);
|
|
\end{verbatim}
|
|
|
|
This way is also useful to create read/write memory stream:
|
|
|
|
\begin{verbatim}
|
|
wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::read\_write);
|
|
wxOutputStream *output = new wxOutputStream(sb);
|
|
wxInputStream *input = new wxInputStream(sb);
|
|
|
|
// If there are data
|
|
sb->SetBufferIO(data, data\_end);
|
|
// Else
|
|
sb->Fixed(FALSE);
|
|
\end{verbatim}

\membersection{wxMemoryOutputStream::wxMemoryOutputStream}
|
|
|
|
\func{}{wxMemoryOutputStream}{\param{char *}{ data = NULL}, \param{size\_t}{ length = 0}}
|
|
|
|
If \it{data} is NULL, then it will initialize a new empty buffer which will
|
|
grow when it needs.
|
|
|
|
\wxheading{Warning}
|
|
|
|
If the buffer is created, it will be destroyed at the destruction of the
|
|
stream.

\membersection{wxMemoryOutputStream::\destruct{wxMemoryOutputStream}}
|
|
|
|
\func{}{\destruct{wxMemoryOutputStream}}{\void}
|
|
|
|
Destructor.
