public abstract class SourceChecker
extends AbstractTypeProcessor
implements ErrorHandler, CFContext, OptionConfiguration
```
An abstract annotation processor designed for implementing a source-file checker for a JSR-308 conforming compiler plug-in. It provides an interface to javac's annotation processing API, routines for error reporting via the JSR 199 compiler API, and an implementation for using a SourceVisitor to perform the type-checking.
Subclasses must implement the following methods: (TODO: update the list)
- getMessages() (for type-qualifier specific error messages)
- createSourceVisitor() (for a custom SourceVisitor)
- getSuppressWarningsKeys() (for honoring @{link SuppressWarnings} annotations)
Most type-checker plug-ins will want to extend BaseTypeChecker, instead of this class. Only checkers that require annotated types but not subtype checking (e.g. for testing purposes) should extend this. Non-type checkers (e.g. for enforcing coding styles) should extend AbstractProcessor (or even this class) as the Checker Framework is not designed for such checkers.

  - getMessages
```
public Properties getMessages()
```
    Provides a mapping of error keys to custom error messages.
    As a default, this implementation builds a Properties out of file messages.properties. It accumulates all the properties files in the Java class hierarchy from the checker up to SourceChecker. This permits subclasses to inherit default messages while being able to override them.
    
    Returns:
    
    a Properties that maps error keys to error message text
  - errorAbort
```
public void errorAbort(String msg)
```
    Log an error message and abort processing. Call this method instead of raising an exception.
    
    Specified by:
    
    errorAbort in interface ErrorHandler
    
    Parameters:
    
    msg - the error message to log
  - errorAbort
```
public void errorAbort(String msg,
                       Throwable cause)
```
    Log an error message and abort processing. Call this method instead of raising an exception.
    
    Specified by:
    
    errorAbort in interface ErrorHandler
    
    Parameters:
    
    msg - the error message to log
    
    cause - the original error cause
  - userErrorAbort
```
public void userErrorAbort(String msg)
```
    Log a user error message and abort processing. Call this method instead of raising an exception or using System.out. In contrast to errorAbort(String) this method presents a more user-friendly output.
    
    Parameters:
    
    msg - the error message to log
  - typeProcessingStart
```
public void typeProcessingStart()
```
    A method to be called once before the first call to typeProcess.
    Subclasses may override this method to do any initialization work.
    Type-checkers are not supposed to override this. Instead use initChecker. This allows us to handle CheckerError only here and doesn't require all overriding implementations to be aware of CheckerError.
    
    Overrides:
    
    typeProcessingStart in class AbstractTypeProcessor
    
    See Also:
    
    AbstractProcessor.init(ProcessingEnvironment), initChecker()
  - initChecker

Returns true if the element is within the scope of a @SuppressWarnings annotation, one of whose values suppresses the checker's warnings. The list of keys that suppress a checker's warnings is provided by the getSuppressWarningsKeys() method.
    
    Parameters:
    
    elt - the Element that might be a source of, or related to, a warning
    
    errKey - the error key the checker is emitting

    src - the position object associated with the result
  - getLintOption
```
public final boolean getLintOption(String name)
```
    Determines the value of the lint option with the given name. Just as javac uses "-Xlint:xxx" to enable and "-Xlint:-xxx" to disable option xxx, annotation-related lint options are enabled with "-Alint:xxx" and disabled with "-Alint:-xxx".
    
    Parameters:
    
    name - the name of the lint option to check for
    
    Returns:
    
    true if the lint option was given, false if it was not given or was given prepended with a "-"

  - getLintOption
```
public final boolean getLintOption(String name,
                                   boolean def)
```
    Determines the value of the lint option with the given name. Just as javac uses "-Xlint:xxx" to enable and "-Xlint:-xxx" to disable option xxx, annotation-related lint options are enabled with "-Alint=xxx" and disabled with "-Alint=-xxx".
    
    Parameters:
    
    name - the name of the lint option to check for
    
    def - the default option value, returned if the option was not given
    
    Returns:
    
    true if the lint option was given, false if it was given prepended with a "-", or def if it was not given at all

    Set the supported lint options. Use of this method should be limited to the AggregateChecker, who needs to set the lint options to the union of all subcheckers. Also, e.g. the NullnessSubchecker/RawnessSubchecker need to use this method, as one is created by the other.
  - addOptions
```
protected void addOptions(Map<String,String> moreopts)
```
    Add additional active options. Use of this method should be limited to the AggregateChecker, who needs to set the active options to the union of all subcheckers.
  - hasOption
```
public final boolean hasOption(String name)
```
    Check whether the given option is provided.
    Note that getOption(String) can still return null even if hasOption returns true: this happens e.g. for -Amyopt

    Specified by:
    
    getSupportedOptions in interface Processor
    
    Specified by:
    
    getSupportedOptions in interface OptionConfiguration
    
    Overrides:
    
    getSupportedOptions in class AbstractProcessor
  - expandCFOptions
```
protected Collection<String> expandCFOptions(List<? extends Class<?>> clazzPrefixes,
                                             String[] options)
```
    Generate the possible command-line option names by prefixing each class name from classPrefixes to options, separated by OPTION_SEPARATOR.
    
    Parameters:
    
    clazzPrefixes - the classes to prefix
    
    options - the option names
    
    Returns:
    
    the possible combinations that should be supported
  - getSupportedAnnotationTypes
```
public final Set<String> getSupportedAnnotationTypes()
```
    Overrides the default implementation to always return a singleton set containing only "*".
    javac uses this list to determine which classes process; javac only runs an annotation processor on classes that contain at least one of the mentioned annotations. Thus, the effect of returning "*" is as if the checker were annotated by @SupportedAnnotationTypes("*"): javac runs the checker on every class mentioned on the javac command line. This method also checks that subclasses do not contain a SupportedAnnotationTypes annotation.
    To specify the annotations that a checker recognizes as type qualifiers, see AnnotatedTypeFactory.createSupportedTypeQualifiers().
    
    Specified by:
    
    getSupportedAnnotationTypes in interface Processor
    
    Overrides:
    
    getSupportedAnnotationTypes in class AbstractProcessor
    
    Throws:
    
    Error - if a subclass is annotated with SupportedAnnotationTypes
  - getSuppressWarningsKeys
```
public Collection<String> getSuppressWarningsKeys()
```
    Returns:
    
    string keys that a checker honors for suppressing warnings and errors that it issues. Each such key suppresses all warnings issued by the checker.
    
    See Also:
    
    SuppressWarningsKeys
  - getStandardSuppressWarningsKeys
```
protected final Collection<String> getStandardSuppressWarningsKeys()
```
    Determine the standard set of suppress warning keys usable for any checker.
    
    Returns:
    
    collection of warning keys
    
    See Also:
    
    getSuppressWarningsKeys()
  - shouldSkipUses
```
public final boolean shouldSkipUses(Element element)
```
    Tests whether the class owner of the passed element is an unannotated class and matches the pattern specified in the checker.skipUses property.
    
    Parameters:
    
    element - an element
    
    Returns:
    
    true iff the enclosing class of element should be skipped
  - shouldSkipUses
```
public boolean shouldSkipUses(String typeName)
```
    Tests whether the class owner of the passed type matches the pattern specified in the checker.skipUses property. In contrast to shouldSkipUses(Element) this version can also be used from primitive types, which don't have an element.
    Checkers that require their annotations not to be checked on certain JDK classes may override this method to skip them. They shall call super.shouldSkipUses(typerName) to also skip the classes matching the pattern.
    
    Parameters:
    
    typeName - the fully-qualified name of a type
    
    Returns:
    
    true iff the enclosing class of element should be skipped
  - shouldSkipDefs
```
public final boolean shouldSkipDefs(ClassTree node)
```
    Tests whether the class definition should not be checked because it matches the checker.skipDefs property.
    
    Parameters:
    
    node - class to potentially skip
    
    Returns:
    
    true if checker should not test node
  - shouldSkipDefs
```
public final boolean shouldSkipDefs(ClassTree cls,
                                    MethodTree meth)
```
    Tests whether the method definition should not be checked because it matches the checker.skipDefs property.
    TODO: currently only uses the class definition. Refine pattern. Same for skipUses.
    
    Parameters:
    
    cls - class to potentially skip
    
    meth - method to potentially skip
    
    Returns:
    
    true if checker should not test node
  - getProperties
```
protected Properties getProperties(Class<?> cls,
                                   String filePath)
```
    A helper function to parse a Properties file.
    
    Parameters:
    
    cls - the class whose location is the base of the file path
    
    filePath - the name/path of the file to be read
    
    Returns:
    
    the properties
