I want declaring an extension func in kotlin but on Java classes Library, I know that do in Kotlin when you resolve companion
in extension function. Like:
class Food {
companion object {
fun foo() = Unit
}
}
fun Food.Companion.clear(){/*Clear all of objects*/}
Now, are there any way for inject a static
function on Java classes library?
No you can't do it. That issue is already in tracked, please check this for more information.
Create a class somewhere in project named Extensions.kt
. It should be looks like this:
package com.examplle.something
fun Food.clear(){
/*Clear all of objects*/
}
fun User.xyz(){
/*Do task XYZ*/
}
No need to make a class for this. It should be out of the class.
So finally we'll have a file Extensions.kt
which contains only the extensions method directly without any class
structure.
