Examples of java.nio.charset.CharsetDecoder.onMalformedInput()

java.nio.charset.CharsetDecoder.onMalformedInput()
Set this decoder's action on malformed input error. This method will call the {@link #implOnMalformedInput(CodingErrorAction) implOnMalformedInput}method with the given new action as argument. @param newAction the new action on malformed input error @return this decoder @throws IllegalArgumentException if the given newAction is null
