THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Background
Protocol
We've been writing a new client-server protocol as a public API for the creation of new Geode clients. We settled on using Protobuf as the encoding for the protocol as it allows a user not to think about a lot of the encoding details, which makes writing clients significantly easier.
...
The message for sending a type definition will look like this:
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
message TypeRegistrationRequest {
ValueTypeDefinition typeDefinition = 1;
}
message TypeRegistrationResponse {
int typeID = 1;
}
message ValueTypeDefinition {
string typeName = 1;
repeated ValueTypeFieldDefinition definition = 2;
}
message ValueTypeFieldDefinition {
string fieldName = 1;
enum fieldType {
intField;
longField;
shortField;
byteField;
booleanField;
doubleField;
floatField;
binaryField;
stringField;
// no JSON? string jsonObjectField;
// Field serialized using a custom serialization format. This can only be used if
// A HandshakeRequest is sent with valueFormat set to a valid format.
//
// See HandshakeRequest.valueFormat.
customObjectField;
}
} |
