<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p><a class="el" href="classwx_temp_file.html" title="wxTempFile provides a relatively safe way to replace the contents of the existing file...">wxTempFile</a> provides a relatively safe way to replace the contents of the existing file. </p>
<p>The name is explained by the fact that it may be also used as just a temporary file if you don't replace the old file contents.</p>
<p>Usually, when a program replaces the contents of some file it first opens it for writing, thus losing all of the old data and then starts recreating it. This approach is not very safe because during the regeneration of the file bad things may happen: the program may find that there is an internal error preventing it from completing file generation, the user may interrupt it (especially if file generation takes long time) and, finally, any other external interrupts (power supply failure or a disk error) will leave you without either the original file or the new one.</p>
<p><a class="el" href="classwx_temp_file.html" title="wxTempFile provides a relatively safe way to replace the contents of the existing file...">wxTempFile</a> addresses this problem by creating a temporary file which is meant to replace the original file - but only after it is fully written. So, if the user interrupts the program during the file generation, the old file won't be lost. Also, if the program discovers itself that it doesn't want to replace the old file there is no problem - in fact, <a class="el" href="classwx_temp_file.html" title="wxTempFile provides a relatively safe way to replace the contents of the existing file...">wxTempFile</a> will <b>not</b> replace the old file by default, you should explicitly call <a class="el" href="classwx_temp_file.html#a3483386ef70cd83a2919054a681f2892" title="Validate changes: deletes the old file of name m_strName and renames the new file to the old name...">wxTempFile::Commit()</a> to do it. Calling <a class="el" href="classwx_temp_file.html#ae4154e93bcd87a48293e38666e2e10a8" title="Discard changes: the old file contents are not changed, the temporary file is deleted.">wxTempFile::Discard()</a> explicitly discards any modifications: it closes and deletes the temporary file and leaves the original file unchanged. If you call neither <a class="el" href="classwx_temp_file.html#a3483386ef70cd83a2919054a681f2892" title="Validate changes: deletes the old file of name m_strName and renames the new file to the old name...">Commit()</a> nor <a class="el" href="classwx_temp_file.html#ae4154e93bcd87a48293e38666e2e10a8" title="Discard changes: the old file contents are not changed, the temporary file is deleted.">Discard()</a>, the destructor will call <a class="el" href="classwx_temp_file.html#ae4154e93bcd87a48293e38666e2e10a8" title="Discard changes: the old file contents are not changed, the temporary file is deleted.">Discard()</a> automatically.</p>
<p>To summarize: if you want to replace another file, create an instance of <a class="el" href="classwx_temp_file.html" title="wxTempFile provides a relatively safe way to replace the contents of the existing file...">wxTempFile</a> passing the name of the file to be replaced to the constructor. (You may also use default constructor and pass the file name to <a class="el" href="classwx_temp_file.html#a9c6a42adfae433ce7928fb77ac769291" title="Open the temporary file, returns true on success, false if an error occurred.">wxTempFile::Open</a>.) Then you can write to <a class="el" href="classwx_temp_file.html" title="wxTempFile provides a relatively safe way to replace the contents of the existing file...">wxTempFile</a> using wxFile-like functions and later call <a class="el" href="classwx_temp_file.html#a3483386ef70cd83a2919054a681f2892" title="Validate changes: deletes the old file of name m_strName and renames the new file to the old name...">wxTempFile::Commit()</a> to replace the old file (and close this one) or call <a class="el" href="classwx_temp_file.html#ae4154e93bcd87a48293e38666e2e10a8" title="Discard changes: the old file contents are not changed, the temporary file is deleted.">wxTempFile::Discard()</a> to cancel the modifications.</p>
