APPENDIX C. COMMON LISP STREAMS

A subclass of fundamental-stream that implements input streams.

=> input-stream-p object [Generic Function]
Returns true when called on any object that is a member of the class fundamental-input-
stream. It may return true for other objects that are not members of the fundamental-input-
stream class, but claim to serve as input streams.

=> fundamental-output-stream [Class]
A subclass of fundamental-stream that implements output streams.

=> output-stream-p object [Generic Function]
Returns true when called on any object that is a member of the class fundamental-output-
stream. It may return true for other objects that are not members of the fundamental-output-
stream class, but claim to serve as output streams.

Bidirectional streams can be formed by including both fundamental-input-stream and fundamental-
output-stream.

=> fundamental-character-stream [Class]
A subclass of fundamental-stream. It provides a method for stream-element-type, which
returns character.

=> fundamental-binary-stream [Class]
A subclass of fundamental-stream. Any instantiable class that includes this needs to define a
method for stream-element-type.

=> fundamental-character-input-stream [Class]
A subclass of both fundamental-input-stream and fundamental-character-stream. It pro-
vides default methods for several generic functions used for character input.

=> fundamental-character-output-stream [Class]
A subclass of both fundamental-output-stream and fundamental-character-stream. It pro-
vides default methods for several generic functions used for character output.

=> fundamental-binary-input-stream [Class]
A subclass of both fundamental-input-stream and fundamental-binary-stream.

=> fundamental-binary-output-stream [Class]
A subclass of both fundamental-output-stream and fundamental-binary-stream.
