Constants ​

go
const KPackageName = "ftracer"

Variables ​

go
var GetFountainInstance = Lib.GetFountainInstance

go
var GetFountainManager = Lib.GetFountainManager

Sử dụng khi config instance ở dạng key:value; Nếu config instance ở dạng key:array thì sử dụng hàm InstallFountainInstances Nếu config ở dạng key:array thì sẽ chỉ install config phần tử đầu tiên mà thôi

Install with config format <key>:<value>; eg: ftracer:<value>

Usage:

config.yaml:

ftracer:
  - name: default_name
    ...

code.go

ftracer.InstallFountainInstance()

ftracer.WithConfigKey("ftracer").InstallFountainInstance()
go
var InstallFountainInstance = Lib.InstallFountainInstance

Sử dụng khi config instance ở dạng key:array<value>; Sẽ luôn cố gắng khởi tạo kể cả khi config ở dạng key:value

Install with config format <key>:array<value>; eg: ftracer:array<value>

Usage:

config.yaml:

ftracer:
  - name: default_name
    ...

code.go

ftracer.InstallFountainInstances()

ftracer.WithConfigKey("ftracer").InstallFountainInstances()
go
var InstallFountainInstances = Lib.InstallFountainInstances
