Method Details

parseProperties

void parseProperties(ClassModel classModel,
 JsonbAnnotatedElement<Class<?>> classElement)

Parse class fields and getters setters. Merge to java bean like properties.

mergePropertyModels

private static void mergePropertyModels(List<PropertyModel> unsortedMerged)

parseClassAndInterfaceMethods

private void parseClassAndInterfaceMethods(JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

parseIfaceMethodAnnotations

private void parseIfaceMethodAnnotations(Class<?> ifc,
 JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

registerMethod

private Property registerMethod(String propertyName,
 Method method,
 JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

parseMethods

private void parseMethods(Class<?> clazz,
 JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

isSpecialCaseMethod

private static boolean isSpecialCaseMethod(Class<?> clazz,
 Method m)

Filter out certain methods that get forcibly added to some classes. For example the public groovy.lang.MetaClass X.getMetaClass() method from Groovy classes

isGetter

private static boolean isGetter(Method m)

isSetter

private static boolean isSetter(Method m)

toPropertyMethod

private static String toPropertyMethod(String name)

lowerFirstLetter

private static String lowerFirstLetter(String name)

isPropertyMethod

private static boolean isPropertyMethod(Method m)

parseFields

private static void parseFields(JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

checkPropertyNameClash

private static void checkPropertyNameClash(List<PropertyModel> collectedProperties,
 Class<?> cls)

getSortedParentProperties

private List<PropertyModel> getSortedParentProperties(ClassModel classModel,
 JsonbAnnotatedElement<Class<?>> classElement,
 Map<String,Property> classProperties)

Merges current class properties with parent class properties. If javabean property is declared in more than one inheritance levels, merge field, getters and setters of that property.

For example BaseClass contains field foo and getter getFoo. In BaseExtensions there is a setter setFoo. All three will be merged for BaseExtension.

Such property is sorted based on where its getter or field is located.

selectMostSpecificNonDefaultMethod

private static Method selectMostSpecificNonDefaultMethod(Method current,
 Method parent)

Select the correct method to use. The correct method is the most specific method which is not a default one:

• if current is not defined, returns parent;
• if parent is not defined, returns current;
• if current is a default method and parent is not, returns parent;
• By definition, it is not possible to make a choice betweentwo default methods.
  Here, the most specific is selected, but a concrete implementation MUST eventually be provided as the source code won't even compile if such a method does not exist
• returns current otherwise

Parameters:

current - current 'child' implementation

parent - parent implementation

Returns:

effective method to register as getter or setter

mergeProperty

private static Property mergeProperty(Property current,
 PropertyModel parentProp,
 JsonbAnnotatedElement<Class<?>> classElement)
