editor-stream-out-base% : class?
superclass: object%

An editor-stream-out-base% object is used by an editor-stream-out% object to perform low-level writing of data.

The editor-stream-out-base% class is never instantiated directly, but the derived class editor-stream-out-bytes-base% can be instantiated. New derived classes must override all of the methods described in this section.

(send an-editor-stream-out-base bad?) → boolean?

Returns #t if there has been an error writing to the stream, #f otherwise.

(send an-editor-stream-out-base seek pos) → void?
pos : nonnegative-exact-integer?

Moves to the specified absolute position in the stream.

(send an-editor-stream-out-base tell)
→ nonnegative-exact-integer?

Returns the current stream position.

(send an-editor-stream-out-base write data) → void?
data : bytes?

Writes data to the stream.
