Field Details

referenceContext

public TypeDeclaration referenceContext

superTypeReference

public TypeReference superTypeReference

resolvingPolyExpressionArguments

public boolean resolvingPolyExpressionArguments

insideEarlyConstructionContext

public boolean insideEarlyConstructionContext

This is the primary flag for detection of early construction contexts (JEP 482). It is temporarily set on the scope of a class while processing statements of this class's early construction context (during resolveType(), analyseCode() and generateCode())

Main access is via Scope.enterEarlyConstructionContext(), Scope.leaveEarlyConstructionContext() and Scope.isInsideEarlyConstructionContext(TypeBinding, boolean).

For the case of LambdaExpression this information is captured during resolve into scopesInEarlyConstruction, for use during generateCode(), which doesn't have the context of the lambda declaration.

All this is always active at compliance 23, see JavaFeature.FLEXIBLE_CONSTRUCTOR_BODIES for details on where enablement is actually checked.

Method Details

checkParameterizedSuperTypeCollisions

public void checkParameterizedSuperTypeCollisions()

public void checkParameterizedTypeBounds()

detectHierarchyCycle

public boolean detectHierarchyCycle(TypeBinding superType,
 TypeReference reference)

problemReporter

public ProblemReporter problemReporter()

Description copied from class: Scope

See also the contract of ProblemReporter.close().

Specified by:

problemReporter in class Scope

referenceType

public TypeDeclaration referenceType()

enclosingMethod

public final MethodBinding enclosingMethod()

hasDefaultNullnessFor

public boolean hasDefaultNullnessFor(int location,
 int sourceStart)

Description copied from class: Scope

Answer a defaultNullness defined for the closest enclosing scope, using bits from Binding.NullnessDefaultMASK.

Overrides:

hasDefaultNullnessFor in class Scope

checkRedundantDefaultNullness

public Binding checkRedundantDefaultNullness(int nullBits,
 int sourceStart)

Description copied from class: Scope

Check whether the given null default is redundant at the given position inside this scope.

Overrides:

checkRedundantDefaultNullness in class Scope

Parameters:

nullBits - locally defined nullness default, see Binding.NullnessDefaultMASK

Returns:

enclosing binding that already has a matching NonNullByDefault annotation, or the special binding Scope.NOT_REDUNDANT, indicating that a different enclosing nullness default was found, or null to indicate that no enclosing nullness default was found.

toString

public String toString()

Overrides:

toString in class Object

addDepth

public int addDepth()

invocationType

public SourceTypeBinding invocationType()

Description copied from class: Scope

For Java scopes, the invocationType is always the same as the enclosingSourceType This distinction is important for AspectJ's inter-type declarations For inter-type declarations, the invocationType is the lexically enclosing type.

Overrides:

invocationType in class Scope
