Let's say you have a proto defined as the following:
syntax = "proto3";
package shelley.messages.zoo;
option java_multiple_files = true;
option java_package = "com.shelley.grpc.messages.zoo";
message Zoo {
repeated Cat cats = 1;
}
.......
Let's say cat looks like this:
message Cat {
google.protobuf.StringValue name = 1
Decimal age = 2;
}
If I want to reduce the amount of data in Zoo such that sample data only
contains `Cat` with only the name field, how do I do that?
Example:
A sample Zoo object will look like this:
{
Cat: [{
name = "sam";
},
{
name = "hester";
}]
}
I'm trying to do this with one field mask:
FieldMask zoo_mask = FieldMask.newBuilder()
.addPaths(*"cats**"*)
.build();
Zoo getMaskedZoo(FieldMask mask, Zoo zoo) {
Zoo.Builder zooDest = Zoo.newBuilder();
FieldMaskUtil.merge(zoo_mask, zoo, zooDest);
*return zooDest.build();*
}
^^How do I make it so that only the name displays for each `Cat`?
