The populate plugin generates a NewPopulated function.
|
||
|
|
This function returns a newly populated structure.
|
||
|
|
|
||
|
|
It is enabled by the following extensions:
|
||
|
|
|
||
|
|
- populate
|
||
|
|
- populate_all
|
||
|
|
|
||
|
|
Let us look at:
|
||
|
|
|
||
|
|
github.com/gogo/protobuf/test/example/example.proto
|
||
|
|
|
||
|
|
Btw all the output can be seen at:
|
||
|
|
|
||
|
|
github.com/gogo/protobuf/test/example/*
|
||
|
|
|
||
|
|
The following message:
|
||
|
|
|
||
|
|
option (gogoproto.populate_all) = true;
|
||
|
|
|
||
|
|
message B {
|
||
|
|
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
|
||
|
|
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
|
||
|
|
}
|
||
|
|
|
||
|
|
given to the populate plugin, will generate code the following code:
|
||
|
|
|
||
|
|
func NewPopulatedB(r randyExample, easy bool) *B {
|
||
|
|
this := &B{}
|
||
|
|
v2 := NewPopulatedA(r, easy)
|
||
|
|
this.A = *v2
|
||
|
|
if r.Intn(10) != 0 {
|
||
|
|
v3 := r.Intn(10)
|
||
|
|
this.G = make([]github_com_gogo_protobuf_test_custom.Uint128, v3)
|
||
|
|
for i := 0; i < v3; i++ {
|
||
|
|
v4 := github_com_gogo_protobuf_test_custom.NewPopulatedUint128(r)
|
||
|
|
this.G[i] = *v4
|
||
|
|
}
|
||
|
|
}
|
||
|
|
if !easy && r.Intn(10) != 0 {
|
||
|
|
this.XXX_unrecognized = randUnrecognizedExample(r, 3)
|
||
|
|
}
|
||
|
|
return this
|
||
|
|
}
|
||
|
|
|
||
|
|
The idea that is useful for testing.
|
||
|
|
Most of the other plugins' generated test code uses it.
|
||
|
|
You will still be able to use the generated test code of other packages
|
||
|
|
if you turn off the popluate plugin and write your own custom NewPopulated function.
|
||
|
|
|
||
|
|
If the easy flag is not set the XXX_unrecognized and XXX_extensions fields are also populated.
|
||
|
|
These have caused problems with JSON marshalling and unmarshalling tests.
