\section{\class{wxTempFileOutputStream}}\label{wxtempfileoutputstream}
|
|
|
|
wxTempFileOutputStream is an output stream based on \helpref{wxTempFile}{wxtempfile}. It
|
|
provides a relatively safe way to replace the contents of the
|
|
existing file.

|
|
Associates wxTempFileOutputStream with the file to be replaced and opens it. You should use
|
|
\helpref{IsOk}{wxstreambaseisok} to verify if the constructor succeeded.
|
|
|
|
Call \helpref{Commit()}{wxtempfileoutputstreamcommit} or \helpref{Close()}{wxoutputstreamclose} to
|
|
replace the old file and close this one. Calling \helpref{Discard()}{wxtempfileoutputstreamdiscard}
|
|
(or allowing the destructor to do it) will discard the changes.

Validate changes: deletes the old file of the given name and renames the new
|
|
file to the old name. Returns {\tt true} if both actions succeeded. If {\tt false} is
|
|
returned it may unfortunately mean two quite different things: either that
|
|
either the old file couldn't be deleted or that the new file couldn't be renamed
|
|
to the old name.

|

|
|
\func{void}{Discard}{\void}
|
|
|
|
Discard changes: the old file contents are not changed, the temporary file is
|
|
deleted.
