# Add new output type
|
||
|
|
|
||
|
|
Write a new package to implement the interface [output.Output:](https://github.com/FreifunkBremen/yanic/blob/master/output/output.go)
|
||
|
|
|
||
|
|
```go
|
||
|
|
type Output interface {
|
||
|
|
Save(nodes *runtime.Nodes)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
**Save** a pre-filtered state of the Nodes
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
For startup, you need to bind your output type by calling
|
||
|
|
`output.RegisterAdapter("typeofoutput",Register)`
|
||
|
|
|
||
|
|
it should be in the `func init() {}` of your package.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The _typeofoutput_ is used as mapping in the configuration `[[nodes.output.typeofoutput]]` the `map[string]interface{}` of the content are parsed to the _Register_ and on of your implemented `Output` or a `error` is needed as result.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Short: the function signature of _Register_ should be `func Register(configuration map[string]interface{}) (Output, error)`
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
At last add you import string to compile the your database as well in this [all](https://github.com/FreifunkBremen/yanic/blob/master/output/all/main.go) package.
