Method Detail

getFirstParameterizedType

public Class<?> getFirstParameterizedType(Field field)

method to get the first type of given parameterized field. If field has no generic type, NULL will be returned.

Parameters:

field -

Returns:

returns first generic type of specified field or NULL if not available.

getElementTargetType

public Class<?> getElementTargetType(Field field)

method to get the target type of given field. This means if field is a list, it will return the generic type.

Parameters:

field -

Returns:

returns generic type of list if field has the type List, else type of field will be returned. If list has no generic type, result will be NULL.

getFieldTypeInfo

public FieldTypeInfo getFieldTypeInfo(Field field,
                                      Object bean)

This method will generate a FieldTypeInfo object with provided information.

Parameters:

field -

bean -

Returns:

getField

public Field getField(String name,
                      Class<?> clazz)
               throws Exception

getAnnotatedMethodWith

public Method getAnnotatedMethodWith(Class<?> targetClass,
                                     Class<?> annotation,
                                     Class<?> returnType)

this method returns the first method of given class with specified annotation and return type. It will also include methods of super classes.

Parameters:

targetClass -

annotation -

returnType - returnType of method (NULL will ignore this criteria), comparing will use equals-method

Returns:

returns first method of given class and its super classes with given annotation and specified return type.

getAnnotatedMethodsWith

public List<Method> getAnnotatedMethodsWith(Class<?> targetClass,
                                            Class<?> annotation,
                                            Class<?> returnType)

this method returns a list with all methods for given class with specified annotation and return type. It will also include methods of super classes.

Parameters:

targetClass -

annotation -

returnType - returnType of method (NULL will ignore this criteria), comparing will use equals-method

Returns:

returns a list with methods of given class and its superclasses with given annotation and specified return type.

getTypeAnnotation

public <T extends Annotation> T getTypeAnnotation(Class<T> annotationClazz,
                                                  Class<?> clazz)

this method returns target annotation instance of given class or one of its super classes.

Parameters:

annotationClazz - target annotation class

clazz - target class

Returns:

returns instance of target annotation or NULL if not exists in target class or one of its super classes

setFieldValue

public <T> void setFieldValue(String name,
                              Object bean,
