Method Detail |
public Twine optNextLine(boolean atTop, boolean quoted, int indent, char closer, int closeIndent) throws IOException
atTop
- Is this the beginning of a top-level unit (typically, a
top-level expression)?quoted
- Will this next line be taken as literal text? If so,
then it should not be trimmed or indented. 'quoted' is
true between double quotes, or between quasi-quotes when
not inside a $ or @ hole.indent
- The suggested indentation level for the next line,
unless the next line begins with closer.closer
- The character that would close the most recent unclosed
openner.closeIndent
- The suggested indentation level for the next line
if it does begin (after trimming) with closer.
