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%.

(make-object string-snip% [allocsize]) → (is-a?/c string-snip%)

allocsize : nonnegative-exact-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.

(send a-string-snip insert s len [pos]) → void?

s : string?

len : nonnegative-exact-integer?

pos : nonnegative-exact-integer? = 0

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

(send a-string-snip read len f) → void?

len : nonnegative-exact-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.
