Method Detail

getValueStack

public static Map<String,Object> getValueStack()

getAsElement

public static TypeElement getAsElement(TypeMirror type)

asElement

public static TypeElement asElement(TypeMirror type)

isSame

public static boolean isSame(TypeMirror type1,
                             TypeMirror type2)

hasType

public static boolean hasType(Element e,
                              CharSequence fqn)

getSingleValueType

public static TypeMirror getSingleValueType(Element e)

getName

public static String getName(Element e)

name as alias for getSimpleName().toString().

getAt

public static org.eclipse.xtext.xbase.lib.Functions.Function1<String,org.eclipse.xtext.xbase.lib.Functions.Function1<CharSequence,Object>> getAt(Element e)

The annotations of the element as Function from annotation class name to annotation, where annotation is again a function from annotation value name to annotation value. "At" == @ == Annotation

_getSingleValue

protected static Object _getSingleValue(Iterable<?> values)

_getSingleValue

protected static Object _getSingleValue(Object value)

get

public static Object get(org.eclipse.xtext.xbase.lib.Functions.Function1<String,?> function,
                         String propertyName)

An Xtend closure with one (String) parameter can be used like "closure.fooBar". In this case, the closure is called with "foobar" as param. (F.E. annotationsByName above returns such a closure. So, one can do things like annotatedClass.at.JapkitEntity to get a JapkitEntity annotation)

get

public static Object get(AnnotationMirror am,
                         String avName)

Allows to write something like "annotation.entityClass" to access the annotation value "entityClass" of the annotation

get

public static Object get(Element e,
                         String functionName,
                         Map<String,Object> context)

Allows to apply functions on the values stack like this: element.functionName

                         String functionName)
