Parameters:

overriderTree - the AST node of the overriding method or method reference

overrider - the type of the overriding method

overridingType - the type enclosing the overrider method, usually an AnnotatedDeclaredType; for Method References may be something else

overridingReturnType - the return type of the overriding method

overridden - the type of the overridden method

overriddenType - the declared type enclosing the overridden method

overriddenReturnType - the return type of the overridden method

Method Details

checkReceiverOverride

protected boolean checkReceiverOverride()

Extend the receiver part of the method override check. We extend the standard check, to additionally permit narrowing the receiver's permission to @AlwaysSafe in a safe instantiation of a @PolyUIType. Returns true if the override is permitted.

Overrides:

checkReceiverOverride in class BaseTypeVisitor<GuiEffectTypeFactory>.OverrideChecker

Returns:

true if the override is legal
