getPropertyOrFieldValue

private <A> Object getPropertyOrFieldValue(A a,
                                           String fieldName)

Get property value first and in case of error try field value.

This method supports nested field/property (e.g. "address.street.number").

Type Parameters:

A - the actual type

Parameters:

a - the object to get field value from

fieldName - Field name to read, can be nested

Returns:

(nested) field value or property value if field was not accessible.

Throws:

IntrospectionError - is field value can't get retrieved.

getDeclaredFieldsIncludingInherited

public static Set<Field> getDeclaredFieldsIncludingInherited(Class<?> clazz)

Returns the declared fields of given class and its superclasses stopping at superclass in java.lang package whose fields are not included.

Parameters:

clazz - the class we want the declared fields.

Returns:

the declared fields of given class and its superclasses.

getDeclaredFieldsIgnoringSyntheticAndStatic

private static Set<Field> getDeclaredFieldsIgnoringSyntheticAndStatic(Class<?> clazz)

Returns the declared fields of a given class excluding any synthetic or static fields. Synthetic fields are fields that are generated by the compiler for access purposes, or by instrumentation tools e.g. JaCoCo adds in a $jacocoData field and therefore should be ignored when comparing fields. Static fields are used as constants, and are not associated with an object.

Parameters:

clazz - the class we want the declared fields.

Returns:

the declared fields of given class excluding any synthetic fields.
