The editor-stream-in-base% class is never instantiated directly, but the derived class editor-stream-in-bytes-base% can be instantiated. New derived classes must override all of the methods described in this section.
→ exact-nonnegative-integer? data : (and/c vector? (not immutable?))
(send an-editor-stream-in-base read-bytes bstr [ start end]) → exact-nonnegative-integer? bstr : (and/c bytes? (not immutable?)) start : exact-nonnegative-integer? = 0 end : exact-nonnegative-integer? = (bytes-length bstr)
The bytes that are read are stored in bstr starting at position start and going to at most to end.
