I created an extension function for rxjava2's Observable class. How do you invoke an extension function from Java code?

[muralimohan962]

You have to pass the observable object as it's first parameter and then other parameters if any as well

[muralimohan962]

You cannot call it on the object as if it is a member function but rather as a normal utility function

[lawlorslaw]

Can you paste a snippet of what that looks like

[lawlorslaw]

that seems to defeat the purpose of an extension function

[lawlorslaw]

since you cant invoke it like
string.fooBar()

[lawlorslaw]

i guess ill just resort to ObservableTransformer

[muralimohan962]

foorBar("Something");

[muralimohan962]

Entensions doesn't work in Java the way they do in Kotlin

[muralimohan962]

Under the hood that is how they are implemented in bytecode. Please decompile any kotlin file by clicking Tools -> Kotlin -> Bytecode and then click decompile in the bytecode window.
