\class CodeChunk
\brief The CodeChunk class represents a tiny piece of C++ code.
\note I think this class should be eliminated (mws 11/12/2018
The class provides conversion between a list of lexemes and a string. It adds
spaces at the right place for consistent style. The tiny pieces of code it
represents are data types, enum values, and default parameter values.
Apart from the piece of code itself, there are two bits of metainformation
stored in CodeChunk: the base and the hotspot. The base is the part of the
piece that may be a hypertext link. The base of
QMap<QString, QString>
is QMap.
The hotspot is the place the variable name should be inserted in the case of a
variable (or parameter) declaration. The hotspot of
char * []
is between '*' and '[]'.
*/
/*!
Appends \a lexeme to the current string contents, inserting
a space if appropriate.
*/
void CodeChunk::append(const QString &lexeme)
{
if (!m_str.isEmpty() && !lexeme.isEmpty()) {
/*
Should there be a space or not between the code chunk so far and the
new lexeme?
*/
int cat1 = category(m_str.at(m_str.size() - 1));
int cat2 = category(lexeme[0]);
if (needSpace[cat1][cat2])
m_str += QLatin1Char(' ');
}
m_str += lexeme;
