Parameters:

length - the length.

Returns:

the Byte[]

newRandomObject

public static <T> T newRandomObject(@NonNull
                                    @NonNull java.lang.Class<T> cls,
                                    java.lang.String... ignoreFieldNames)
                             throws java.lang.IllegalAccessException,
                                    java.lang.InstantiationException,
                                    java.lang.NoSuchFieldException

Factory method for create a new random object of the given Class.

Type Parameters:

T - the generic type

Parameters:

cls - the class

ignoreFieldNames - an optional array with the field names that shell be ignored

Returns:

the new random object

Throws:

java.lang.IllegalAccessException - is thrown if the class or its default constructor is not accessible.

java.lang.InstantiationException - is thrown if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no default constructor; or if the instantiation fails for some other reason.

java.lang.NoSuchFieldException - is thrown if no such field exists

setRandomValues

public static <T> T setRandomValues(@NonNull
                                    @NonNull java.lang.Class<T> cls,
                                    @NonNull
                                    T instance,
                                    java.lang.String... ignoreFieldNames)
                             throws java.lang.IllegalAccessException,
                                    java.lang.InstantiationException,
                                    java.lang.NoSuchFieldException

Sets the random values to the fields of the given instance

Type Parameters:

T - the generic type

Parameters:

cls - the cls

instance - the instance to set random values

ignoreFieldNames - the ignore field names

Returns:

the new random object

Throws:

java.lang.IllegalAccessException - is thrown if the class or its default constructor is not accessible.

java.lang.InstantiationException - is thrown if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no default constructor; or if the instantiation fails for some other reason.

java.lang.NoSuchFieldException - is thrown if no such field exists
