Introduction

In this page you can find the example usage for io.vertx.core.buffer Buffer appendString.

Prototype

@Fluent
Buffer appendString(String str);

Source Link

Document

Appends the specified String str to the end of the Buffer with UTF-8 encoding.

The buffer will expand as necessary to accommodate any bytes written.

Returns a reference to this so multiple operations can be appended together
