Interface SemanticErrorReporter

public interface SemanticErrorReporter

Reports errors that occur after parsing. This may be used to implement semantic checks in a language specific way.

Method Summary

Modifier and Type	Method	Description
SemanticException	error(Node location, String message, Object... formatArgs)	Report an error at the given location.
@Nullable SemanticException	getFirstError()	If error(Node, String, Object...) has been called, return a semantic exception instance with the correct message.
static SemanticErrorReporter	noop()
static SemanticErrorReporter	reportToLogger(MessageReporter reporter)	Forwards to a MessageReporter, except trace and debug messages which are reported on a logger.
void	warning(Node location, String message, Object... formatArgs)	Report a warning at the given location.

Method Detail

warning

void warning(Node location,
             String message,
             Object... formatArgs)

Report a warning at the given location. Warnings do not abort the analysis. They are usually recoverable errors. They are used to warn the user that something wrong is going on, which may cause subsequent errors or inconsistent behavior.

Parameters:

location - Location where the warning should be reported

message - Message (rendered using a MessageFormat)

formatArgs - Format arguments

error

SemanticException error(Node location,
                        String message,
                        Object... formatArgs)

Report an error at the given location. Errors abort subsequent analysis and cause a processing error to be put in the report. The produced error can be thrown by the caller if it cannot be recovered from.

Parameters:

location - Location where the error should be reported

message - Message (rendered using a MessageFormat)

formatArgs - Format arguments

getFirstError

@Nullable SemanticException getFirstError()

If error(Node, String, Object...) has been called, return a semantic exception instance with the correct message. If it has been called more than once, return the first exception, possibly with suppressed exceptions for subsequent calls to error(Node, String, Object...).

noop

static SemanticErrorReporter noop()

reportToLogger

static SemanticErrorReporter reportToLogger(MessageReporter reporter)

Forwards to a MessageReporter, except trace and debug messages which are reported on a logger.
