## Member Function Documentation

## ◆ dropNullPlaceholders()

void Json::FastWriter::dropNullPlaceholders | ( |  | ) |

Drop the "null" string from the writer's output for nullValues.

Strictly speaking, this is not valid JSON. But when the output is being fed to a browser's Javascript, it makes for smaller output and the browser can handle the output just fine.
