Method Details

isDeepCloned

public static boolean isDeepCloned(SolutionDescriptor<?> solutionDescriptor,
 Field field,
 Class<?> owningClass,
 Class<?> actualValueClass)

Gets the deep cloning decision for a particular value assigned to a field, memoizing the result.

Parameters:

field - the field to get the deep cloning decision of

owningClass - the class that owns the field; can be different from the field's declaring class (ex: subclass)

actualValueClass - the class of the value that is currently assigned to the field; can be different from the field type (ex: for the field "List myList", the actual value class might be ArrayList).

Returns:

true iff the field should be deep cloned with a particular value.

isFieldDeepCloned

public static boolean isFieldDeepCloned(SolutionDescriptor<?> solutionDescriptor,
 Field field,
 Class<?> owningClass)

Gets the deep cloning decision for a field.

Parameters:

field - The field to get the deep cloning decision of

owningClass - The class that owns the field; can be different from the field's declaring class (ex: subclass).

Returns:

True iff the field should always be deep cloned (regardless of value).
