\class ProjectExplorer::IOutputParser
\brief The IOutputParser class provides an interface for an output parser
that emits issues (tasks).
\sa ProjectExplorer::Task
*/
/*!
\fn void ProjectExplorer::IOutputParser::appendOutputParser(IOutputParser *parser)
Appends a subparser to this parser, of which IOutputParser will take
ownership.
*/
/*!
\fn IOutputParser *ProjectExplorer::IOutputParser::takeOutputParserChain()
Removes the appended outputparser chain from this parser, transferring
ownership of the parser chain to the caller.
*/
/*!
\fn IOutputParser *ProjectExplorer::IOutputParser::childParser() const
Returns the head of this parser's output parser children. IOutputParser
keeps ownership.
*/
/*!
\fn void ProjectExplorer::IOutputParser::stdOutput(const QString &line)
Called once for each line if standard output to parse.
*/
/*!
\fn void ProjectExplorer::IOutputParser::stdError(const QString &line)
Called once for each line if standard error to parse.
*/
/*!
\fn bool ProjectExplorer::IOutputParser::hasFatalErrors() const
This is mainly a Symbian specific quirk.
*/
/*!
\fn void ProjectExplorer::IOutputParser::addOutput(const QString &string, ProjectExplorer::BuildStep::OutputFormat format)
Should be emitted whenever some additional information should be added to the
output.
\note This is additional information. There is no need to add each line.
*/
/*!
\fn void ProjectExplorer::IOutputParser::addTask(const ProjectExplorer::Task &task)
Should be emitted for each task seen in the output.
*/
/*!
\fn void ProjectExplorer::IOutputParser::outputAdded(const QString &string, ProjectExplorer::BuildStep::OutputFormat format)
Subparsers have their addOutput signal connected to this slot.
*/
/*!
\fn void ProjectExplorer::IOutputParser::outputAdded(const QString &string, ProjectExplorer::BuildStep::OutputFormat format)
This function can be overwritten to change the string.
*/
/*!
\fn void ProjectExplorer::IOutputParser::taskAdded(const ProjectExplorer::Task &task)
Subparsers have their addTask signal connected to this slot.
This function can be overwritten to change the task.
*/
/*!
\fn void ProjectExplorer::IOutputParser::doFlush()
Instructs a parser to flush its state.
Parsers may have state (for example, because they need to aggregate several
lines into one task). This
function is called when this state needs to be flushed out to be visible.
doFlush() is called by flush(). flush() is called on child parsers
whenever a new task is added.
It is also called once when all input has been parsed.
