findAMethod

public static Method findAMethod(Class<?> clazz,
                                 String methodName)
                          throws NoSuchMethodException

Find a method with concrete string representation of it's parameters

Parameters:

clazz - clazz to search

methodName - name of method with representation of it's parameters

Returns:

found method

Throws:

NoSuchMethodException

getPropertyDescriptors

public static PropertyDescriptor[] getPropertyDescriptors(Class<?> objectClass)

getFieldFromBean

public static Field getFieldFromBean(Class<?> clazz,
                                     String fieldName)

invoke

public static Object invoke(Method method,
                            Object obj,
                            Object[] args)

getMethod

public static Method getMethod(Class<?> clazz,
                               String name,
                               Class<?>[] parameterTypes)
                        throws NoSuchMethodException

Throws:

newInstance

public static <T> T newInstance(Class<T> clazz)

determineGenericsType

public static Class<?> determineGenericsType(Class<?> parentClazz,
                                             PropertyDescriptor propDescriptor)

determineGenericsType

public static Class<?> determineGenericsType(Class<?> clazz,
                                             Method method,
                                             boolean isReadMethod)

determineGenericsType

public static Class<?> determineGenericsType(Type type)

getNonStandardSetter

public static Method getNonStandardSetter(Class<?> clazz,
                                          String fieldName)

Finds non-standard setters PropertyUtils.getPropertyDescriptors(java.lang.Class<?>) does not find. The non-standard setters include

• Setters that return something instead of void
• Setters that take a wrapper argument (e.g. Boolean) when the field is of primitive type (e.g. boolean) - or the other way around.

Parameters:

clazz - The class to find non-standard setters from

fieldName - The field to find a non-standard setter for

Returns:

The non-standard setter or null
