All Implemented Interfaces:

Processor, OptionConfiguration

@SupportedOptions({"quals","qualDirs"})
public final class SubtypingChecker
extends BaseTypeChecker

A checker for type qualifier systems that only checks subtyping relationships.

The annotation(s) are specified on the command line, using an annotation processor argument:

• -Aquals: specifies the annotations in the qualifier hierarchy (as a comma-separated list of fully-qualified annotation names with no spaces in between). Only the annotations for one qualified subtype hierarchy can be passed.

Method Details

getSuppressWarningsPrefixes

public static NavigableSet<String> getSuppressWarningsPrefixes(SourceVisitor<?,?> visitor,
 NavigableSet<String> superSupportedTypeQualifiers)

Compute SuppressWarnings prefixes, based on the names of all the qualifiers.

Provided for the convenience of checkers that do not subclass SubtypingChecker (because it is final). Clients should call it like:

 SubtypingChecker.getSuppressWarningsPrefixes(this.visitor, super.getSuppressWarningsPrefixes());
 

Parameters:

visitor - the visitor

superSupportedTypeQualifiers - the result of super.getSuppressWarningsPrefixes(), as executed by checker

Returns:

SuppressWarnings prefixes, based on the names of all the qualifiers

getSuppressWarningsPrefixes

public NavigableSet<String> getSuppressWarningsPrefixes()

Description copied from class: SourceChecker

Returns a modifiable set of lower-case strings that are prefixes for SuppressWarnings strings.

The collection must not be empty and must not contain only SourceChecker.SUPPRESS_ALL_PREFIX.

Overrides:

getSuppressWarningsPrefixes in class SourceChecker

Returns:

non-empty modifiable set of lower-case prefixes for SuppressWarnings strings
