very simple implementation of a filter chain pattern written in Golang.

### Usage

```go

package main

import (

	"github.com/niedbalski/filterchain"

	"strings"

	"fmt"

)

type TestToLowerFilter struct {}

type TestRepeatFilter struct {}

func (filter TestToLowerFilter) Apply(t interface{}) (interface{}) {

	return strings.ToLower(t.(string))

}

func (filter TestRepeatFilter) Apply(t interface{}) (interface{}) {

	return strings.Repeat(t.(string), 3)

}

func main() {

	fmt.Println(filterchain.New(TestToLowerFilter{}, TestRepeatFilter{}).Apply("TEST"))

}

```

String will be produced as:

```shell

testtestest

```
