I don’t get this factory method stuff :(

[diesieben07]

Simple example:

class CSVParser<T>(val factory: (String) -> T, val file: String)
// inside parse method:
val tInstance: T = factory(line)

class MyClass(line: String)

// create CSVParser instance:
val parser = CSVParser<MyClass>(::MyClass, myFile)

In this example calling factory will call the MyClass constructor.

Thx a lot

Hmmm now compiler says : factory: “ constructor Kotlin reflection not available

[Dominik.sittel]

I have added reflection lib now it works

You can avoid reflection completely, just pass { -> MyClass() } as the factory

[diesieben07]

Just ::MyClass and calling it should work without reflection library, too.
