Igniters,
I was creating an example showing how to use BinaryObjects and
EntryProcessor for the case when server nodes do not have cache classes
definitions and realized that there is no straightforward way to get an
instance of BinaryObjectBuilder inside of an EntryProcessor.
Currently the only way to do this is to inject an instance of Ignite to the
instance of EntryProcessor and get a reference to IgniteBinary from it,
which looks a bit too verbose to me:
class MyEntryProcessor {
@IgniteInstanceResource
private Ignite ignite;
BinaryObject invoke(...) {
BinaryObjectBulder bld = ignite.binary().builder(entry.getValue());
entry.setValue(bld.setField("a", 2).build());
}
}
I think we can add something like a "BinaryBuilder buildCopy();" method to
the BinaryObject interface which will create a new binary builder
initialized with the current binary object. Now the above EntryProcessor
will look as follows:
class MyEntryProcessor {
BinaryObject invoke(...) {
entry.setValue(entry.getValue().buildCopy().setField("a",
2).build());
}
}
Thoughts?
