Class InitializationChecker

java.lang.Object

javax.annotation.processing.AbstractProcessor

org.checkerframework.javacutil.AbstractTypeProcessor

org.checkerframework.framework.source.SourceChecker

org.checkerframework.common.basetype.BaseTypeChecker

org.checkerframework.checker.initialization.InitializationChecker

All Implemented Interfaces:

Processor, BaseTypeContext, BaseContext, CFContext, OptionConfiguration

Direct Known Subclasses:

AbstractNullnessChecker

public abstract class InitializationChecker
extends BaseTypeChecker

Tracks whether a value is initialized (all its fields are set), and checks that values are initialized before being used. Supports two different type systems for initialization: freedom-before-commitment (which is generally preferred) and rawness.

See the Checker Framework Manual:

Field Detail

useFbc

public final boolean useFbc

Should the initialization type system be FBC? If not, the rawness type system is used for initialization.

public InitializationChecker(boolean useFbc)

Method Detail

getSuppressWarningsKeys

public Collection<String> getSuppressWarningsKeys()

Overrides:

getSuppressWarningsKeys in class SourceChecker

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.

SuppressWarningsKeys

getAllFields

public static List<VariableTree> getAllFields(ClassTree clazz)

Returns a list of all fields of the given class.
