How to encode bytes values and array data types?
SeppPenner opened this issue · comments
I have checked
metricBuilder.setBytesValue(ByteString.copyFrom((byte[]) metric.getValue()));
--> I have checked the Protobuf class and seen the following:
public Builder setBytesValue(com.google.protobuf.ByteString value) {
if (value == null) {
throw new NullPointerException();
}
valueCase_ = 16;
value_ = value;
onChanged();
return this;
}
but I don't understand how the data is stored in the value. Is this a Hex-String of the byte stored as string value in Protobuf? The same question for the array data types like In8Array or DateTimeArray. It would be nice if someone could give me an example on what to do here as I'm currently really struggeling with these conversions in my project https://github.com/SeppPenner/SparkplugNet...
I found it, seems like I was missing the bytes value in the Protobuf equivalenbt (Or the bytes value wasn't present for some other types).
