6.77.1. JAVA_STREAM_OUTPUT.new(Stream)

`new` returns an `output` value which wraps a Java OutputStream object.

See kink/io/OUTPUT for `output` type.

Preconditions

`Stream` must be a `java` value.

The object reference of `Stream` must be an instance of java.io.OutputStream.

Example

:JAVA.require_from('kink/javahost/')
:JAVA_STREAM_OUTPUT.require_from('kink/javahost/')
:CONTROL.require_from('kink/')
:BIN.require_from('kink/')

:Baos_class <- JAVA.class('java.io.ByteArrayOutputStream')
:Baos <- Baos_class.new
CONTROL.with_finally{(:finally)
  :Out = JAVA_STREAM_OUTPUT.new(Baos)
  finally{ Out.close }
  Out.write(BIN.of(1 2 3))
  Out.write(BIN.of(4 5))
}
:Bin <- Baos.call_method('toByteArray').to_kink_bin
stdout.print_line(Bin.repr) # => (bin 0x01 0x02 0x03 0x04 0x05)
