Using PostgreSQL COPY FROM STDIN

Is it possible to use PostgreSQL's COPY FROM STDIN statement to load data from CSV file by passing some sort of Reader or Writer object the same way it's done in Java? What library should I use? Kotlin example for reference:

val cm = CopyManager(conn as BaseConnection)
val total = cm.copyIn("COPY my_table FROM STDIN FORMAT csv", inputStream)
