UnicodeString ustr(u"Hello, world!"); UChar* buffer = ustr.releaseBuffer(); // Modify the buffer buffer[0] = u'J'; // Convert the buffer back to a UnicodeString ustr.setTo(buffer);
UnicodeString ustr(u"Hello, world!"); UChar* buffer = ustr.getBuffer(ustr.length()); // Modify the buffer buffer[0] = u'J'; // Release the buffer ustr.releaseBuffer();In this example, we use `getBuffer()` to obtain a writable pointer to the character buffer of the `UnicodeString` object. We then modify the buffer by changing the first character to 'J' and release the buffer using `releaseBuffer()`. Overall, `releaseBuffer()` is a useful function for cases where you need to manipulate the character buffer of a `UnicodeString` object directly. It allows you to avoid unnecessary copying and can potentially improve performance.
