expectedTypes

protected com.sun.tools.javac.util.List<com.sun.tools.javac.code.Type> expectedTypes(Inliner inliner)
                                                                              throws CouldNotResolveImportException

Returns a list of the expected types to be matched. This consists of the argument types from the @BeforeTemplate method, concatenated with the return types of expression placeholders, sorted by the name of the placeholder method.

Throws:

CouldNotResolveImportException - if a referenced type could not be resolved

actualTypes

protected com.sun.tools.javac.util.List<com.sun.tools.javac.code.Type> actualTypes(Inliner inliner)
                                                                            throws CouldNotResolveImportException

Returns a list of the actual types to be matched. This consists of the types of the expressions bound to the @BeforeTemplate method parameters, concatenated with the types of the expressions bound to expression placeholders, sorted by the name of the placeholder method.

Throws:

CouldNotResolveImportException
