type-for-sequence-stream sequence => sequence-stream-type
Arguments
- sequence
- An instance of
<sequence>.
Values
- sequence-stream-type
-
An instance of
<type>.
Library

streams
Description
Returns the sequence-stream class to instantiate over a given sequence object. The method for make on <sequence-stream> calls this function to determine the concrete subclass of <sequence-stream> that it should instantiate.
There are type-for-sequence-stream methods for each of the string object classes. These methods return a stream class object that the Streams module considers appropriate.
