Examples of java.nio.charset.Charset.decode()

java.nio.charset.Charset.decode()
Decodes the content of the give byte buffer and outputs to a character buffer that is to be returned.
The default action in case of decoding errors is CodingErrorAction.REPLACE.
@param buffer the byte buffer containing the content to be decoded @return a character buffer containing the output of the dencoding
