6.9 string-snip%

class
string-snip% :class?

superclass:snip%

An instance of string-snip% is created automatically when text is inserted into a text editor. See also on-new-string-snip in text% .

constructor
( make-object string-snip% [allocsize])→(is-a?/c string-snip% )
allocsize:exact-nonnegative-integer? =0
(make-object string-snip% s)→(is-a?/c string-snip% )
s:string?

Creates a string snip whose initial content is s, if supplied, empty otherwise. In the latter case, the optional allocsize argument is a hint about how much storage space for text should be initially allocated by the snip.

method
(send a-string-snip insert slen[pos])→void?
s:string?
len:exact-nonnegative-integer?
pos:exact-nonnegative-integer? =0

Inserts s (with length len) into the snip at relative position pos within the snip.

method
(send a-string-snip read lenf)→void?
len:exact-nonnegative-integer?
f:(is-a?/c editor-stream-in% )

Reads the snip’s data from the given stream.

The len argument specifies the maximum length of the text to be read. (When a text snip is written to a file, the very first field is the length of the text contained in the snip.) This method is usually invoked by the text snip class’s read method.
