public class InitializationFieldAccessSubchecker
extends BaseTypeChecker

Part of the freedom-before-commitment type system.

This checker does not actually do any type checking. It exists to provide its parent checker (the InitializationChecker.getTargetCheckerClass()) with declared initialization qualifiers via the InitializationFieldAccessTreeAnnotator.

Additionally, this checker performs the flow-sensitive type refinement for the fbc type system, which is necessary to avoid reporting follow-up errors related to initialization (see the AssignmentDuringInitialization test case). To avoid performing the same type refinement twice, the InitializationChecker performs no refinement, instead reusing the results from this checker.

Method Detail

reportError

public void reportError(java.lang.Object source,
                        @CompilerMessageKey java.lang.String messageKey,
                        java.lang.Object... args)

Description copied from class: SourceChecker

Reports an error. By default, prints it to the screen via the compiler's internal messager.

Overrides:

reportError in class SourceChecker

Parameters:

source - the source position information; may be an Element, a Tree, or null

messageKey - the message key

args - arguments for interpolation in the string corresponding to the given message key

reportWarning

public void reportWarning(java.lang.Object source,
                          @CompilerMessageKey java.lang.String messageKey,
                          java.lang.Object... args)

Description copied from class: SourceChecker

Reports a warning. By default, prints it to the screen via the compiler's internal messager.

Overrides:

reportWarning in class SourceChecker

Parameters:

source - the source position information; may be an Element, a Tree, or null

messageKey - the message key

args - arguments for interpolation in the string corresponding to the given message key
