Method Detail

getBoxedReturnType

public static java.lang.String getBoxedReturnType(javax.lang.model.element.ExecutableElement exec)

Gives a string representation of the executable element's return type. If the return type is a primitive (e.g. int, double, etc.), then the returned type will be that primitive's boxed type (e.g. Integer, Double, etc.). In the case that the executable element return has no return type (i.e. `void`), then "void" is returned. An `IllegalArgumentException` is raised whenever the `TypeKind` of `exec`'s return value is any of the following: - NONE - NULL - ERROR - WILDCARD - PACKAGE - EXECUTABLE - OTHER - UNION - INTERSECTION

Parameters:

exec -

Returns:

A string of the executable's return type.

getTypeElement

public static javax.lang.model.element.TypeElement getTypeElement(javax.annotation.processing.ProcessingEnvironment procEnv,
                                                                  java.lang.String className)

getMethodsNamed

public static java.util.List<javax.lang.model.element.ExecutableElement> getMethodsNamed(javax.lang.model.element.TypeElement typeElem,
                                                                                         java.lang.String name)

Returns:

A list of methods on the given `typeElem` whose name matches the given `name`; the returned `ExecutableElement`s are listed in the same order in which the they are defined within the given `typeElem`.

isNamed

public static boolean isNamed(javax.lang.model.element.Element elem,
                              java.lang.String name)

Returns:

`true` if and only if the given executable element has the given name.
