Method Details

clone

public TypeBinding clone(TypeBinding enclosingType)

Description copied from class: TypeBinding

Virtual copy constructor: a copy is made of the receiver's entire instance state and then suitably parameterized by the arguments to the clone operation as seen fit by each type. Parameters may not make sense for every type in the hierarchy, in which case they are silently ignored. A type may choose to retain a copy of the prototype for reference.

Overrides:

clone in class TypeBinding

getInterfaceAbstractContracts

protected MethodBinding[] getInterfaceAbstractContracts(Scope scope,
 boolean replaceWildcards,
 boolean filterDefaultMethods)
                                                 throws org.aspectj.org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding.InvalidBindingException

Overrides:

getInterfaceAbstractContracts in class ReferenceBinding

Throws:

org.aspectj.org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding.InvalidBindingException
