Method Detail

checkDuckability

public Check.Result checkDuckability(javax.lang.model.element.TypeElement toDuck)

Specified by:

checkDuckability in interface DuckabilityCheck

Parameters:

toDuck - A type element representing some type to be ducked.

Returns:

The result of the duckability check: either an OK result or an error result.

checkForIllegalFinalMethod

public Check.Result checkForIllegalFinalMethod(javax.lang.model.element.TypeElement toDuck)

Check to see if the given type element to be ducked has any final methods which are non-private. Currently, such methods cause a type to be unduckable because all visible methods need a facade, but `final` methods cannot be overridden. Therefore a facade cannot be made for all methods of the type.

checkForProblematicProtectedMethod

public Check.Result checkForProblematicProtectedMethod(javax.lang.model.element.TypeElement toDuck)

Checks to see whether a type is both in a protected package and has a package private method. Currently, these cases cannot be correctly ducked, since the duck wrapper cannot be put in these packages and a duck wrapper placed in some other package cannot call a package private method.
