public abstract class AggregateChecker extends SourceChecker
There is no communication, interaction, or cooperation between the component checkers, even to the extent of being able to read one another's qualifiers. An aggregate checker is merely shorthand to invoke a sequence of checkers.
This class delegates AbstractTypeProcessor responsibilities to each component checker.
Checker writers need to subclass this class and only override getSupportedCheckers()
to indicate the classes of the checkers to be bundled.

| Modifier and Type | Method and Description |
|---|---|
protected SourceVisitor<?,?> |
createSourceVisitor()
Provides the
SourceVisitor that the checker should use to scan input source trees. |
Map<String,String> |
getOptions()
Return all active options for this checker.
|
protected abstract Collection<Class<? extends SourceChecker>> |
getSupportedCheckers()
Returns the list of supported checkers to be run together.
|
Set<String> |
getSupportedLintOptions()
Returns the lint options recognized by this checker.
|
Set<String> |
getSupportedOptions()
Map the Checker Framework version of
SupportedOptions to the standard annotation
provided version SupportedOptions. |
void |
initChecker()
Initialize the checker.
|
protected void |
setProcessingEnvironment(ProcessingEnvironment env)
processingEnv needs to be set on each checker since we are not calling init on the checker,
which leaves it null.
|
void |
typeProcess(TypeElement element,
TreePath tree)
Type-check the code using this checker's visitor.
|
void |
typeProcessingOver()
A method to be called once all the classes are processed and no error is reported.

AbstractTypeProcessorSubclasses may override this method to do any aggregate analysis (e.g. generate report, persistence) or resource deallocation.
Method AbstractTypeProcessor.getCompilerLog() can be used to access the number of compiler errors.
