Method Detail

parseWarningLine

protected List<WarningParser.Violation> parseWarningLine(String line)

Description copied from class: WarningParser

Parse a line from the output of the MISRA checker tool (e.g. PC-lint).

Specified by:

parseWarningLine in class WarningParser

Parameters:

line - A single line of text from the parser tools output. The parser should be configured so that a violation does not cover more than one line.

Returns:

A list of MISRA-violations described by this line. If the line does not represent any MISRA-violations, return null or an empty list.

findSuppressionComments

protected List<String> findSuppressionComments(String fileContent)

Description copied from class: WarningParser

Parse the contents of a source code file, and return a list of all suppression comments in the file. A suppression comment is a comment that is used to suppress a warning from the checker tool. For example, for PC-lint this is every comment that starts out with "lint" immediately following the comment opening symbol. The returned string should contain the full text of the comment, including any suppression tokens.

Specified by:

findSuppressionComments in class WarningParser

Parameters:

fileContent - The full contents of the source file as a string

Returns:

A list of all suppression comments in the file

getGuidelineIdsFromComment

protected Set<String> getGuidelineIdsFromComment(String comment)

Description copied from class: WarningParser

For a single suppression comment, find each MISRA violation that is suppressed by this comment.

Note: This is likely the most difficult method to implement, since it may have to map tool error codes to MISRA guidelines. If this mapping is too complex, you can implement this method to always return null. This will force the user to always add a GUIDELINE(...) tag to suppression comments, or end up with an invalid report.

Specified by:

getGuidelineIdsFromComment in class WarningParser

Parameters:

comment - A suppression comment from the source file

Returns:

A set of guidelines suppressed by this comment, e.g "Rule 1.2". Return null or an empty set if no MISRA guidelines are suppressed, or we could not determine which guideline is suppressed by this comment.

name

public String name()

Specified by:

name in class WarningParser

Returns:

The name of this warning parser

supportedMisraVersions

public Set<WarningParser.MisraVersion> supportedMisraVersions()

Description copied from class: WarningParser

Returns the set of all MISRA-guideline versions supported by this warning parser. Override if your warning parser does not support all guideline versions.

Overrides:

supportedMisraVersions in class WarningParser

Returns:

A set of all versions of the MISRA guidelines that are supported by this warning parser.
