org.checkerframework.checker.initialization.InitializationChecker

All Implemented Interfaces:

Processor, BaseTypeContext, BaseContext, CFContext, OptionConfiguration

Direct Known Subclasses:

NullnessChecker

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. Implements the freedom-before-commitment scheme for initialization, augmented by type frames.

Method Detail

getSuppressWarningsPrefixes

public SortedSet<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

getAllFields

public static List<VariableTree> getAllFields(ClassTree clazz)

Returns a list of all fields of the given class.
