sendRequest(env,
rec);
}
// constructor:
addMessageHandler(CRecordGetMicroServiceIds.ID,
this::asyncGetMicroServiceIds);
// reply
private boolean asyncGetMicroServiceIds(@NotNull final CEnvelope aEnvelope,
@NotNull final CRecord aRecord)
{
if (aEnvelope.isAnswer())
{
if (aEnvelope.getResultCode() == CResultCode.SUCCESS)

}Record Usage
In nyssr.net, we typically don't exchange interfaces between projects. Instead, we use platform-independent Records to describe message formats.
One or more descriptions of these Records are stored in the JSON or XML format
as record.json or record.xml within a directory.
The Record Generator, an included Swing tool, generates helper classes from these files.
These classes can then be used to type-safely write or read messages.
