Demo
If we have a struct like this:
type CreateDisk struct {
RegionID string //required for creating CreateDisk struct
ZoneID string //required for creating CreateDisk struct
DiskName string
Description string
Encrypted bool
DiskCategory string
Size int
SnapshotID string
ClientToken string
}
After generated, we got
type CreateDiskBuilder structfor storing *CreateDiskfunc NewCreateDiskBuilder()for creating a builder- functions for receiving parameters
func Build()for checking and building
// CreateDisk builder pattern code
type CreateDiskBuilder struct {
createDisk *CreateDisk
}
func NewCreateDiskBuilder() *CreateDiskBuilder {
createDisk := &CreateDisk{}
b := &CreateDiskBuilder{createDisk: createDisk}
return b
}
func (b *CreateDiskBuilder) RegionID(regionID string) *CreateDiskBuilder {
b.createDisk.RegionID = regionID
return b
}
func (b *CreateDiskBuilder) ZoneID(zoneID string) *CreateDiskBuilder {
b.createDisk.ZoneID = zoneID
return b
}
.
.
.
func (b *CreateDiskBuilder) ClientToken(clientToken string) *CreateDiskBuilder {
b.createDisk.ClientToken = clientToken
return b
}
func (b *CreateDiskBuilder) Build() (*CreateDisk, error) {
// May miss required parameters
return b.createDisk, nil
}
When we use it
createDisk, err := NewCreateDiskBuilder().
DiskName("test name").
Description("desc").
Size(20).
SnapshotID("").
Build()
if err != nil {
// May miss required parameters
return
}
// Do something with createDisk
