Method Details

checkUnusedParameters

public void checkUnusedParameters(MethodBinding method)

computeLocalVariablePositions

public void computeLocalVariablePositions(int initOffset,
 CodeStream codeStream)

Compute variable positions in scopes given an initial position offset ignoring unused local variables. Deal with arguments here, locals and subscopes are processed in BlockScope method

findField

public FieldBinding findField(TypeBinding receiverType,
 char[] fieldName,
 InvocationSite invocationSite,
 boolean needResolve)

Overridden to detect the error case inside an explicit constructor call: class X { int i; X myX; X(X x) { this(i, myX.i, x.i); // same for super calls... only the first 2 field accesses are errors } }

Overrides:

findField in class Scope

getSyntheticEnclosingArgumentOfLambda

protected Object[] getSyntheticEnclosingArgumentOfLambda(ReferenceBinding targetEnclosingType)

isInsideConstructor

public boolean isInsideConstructor()

isInsideInitializer

public boolean isInsideInitializer()

isLambdaScope

public boolean isLambdaScope()

Overrides:

isLambdaScope in class Scope

isInsideInitializerOrConstructor

public boolean isInsideInitializerOrConstructor()

problemReporter

public ProblemReporter problemReporter()

Answer the problem reporter to use for raising new problems. Note that as a side-effect, this updates the current reference context (unit, type or method) in case the problem handler decides it is necessary to abort.

Overrides:

problemReporter in class BlockScope

recordInitializationStates

public final int recordInitializationStates(FlowInfo flowInfo)

referenceMethod

public AbstractMethodDeclaration referenceMethod()

Answer the reference method of this scope, or null if initialization scope or lambda scope.

referenceMethodBinding

public MethodBinding referenceMethodBinding()

Answers the binding of the reference method or reference lambda expression.

referenceType

public TypeDeclaration referenceType()

Answer the reference type of this scope. It is the nearest enclosing type of this scope.

Overrides:

referenceType in class BlockScope

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.

shouldCheckAPILeaks

public boolean shouldCheckAPILeaks(ReferenceBinding declaringClass,
