java.lang.Object

org.apache.juneau.swap.ObjectSwap<StackTraceElement,String>

org.apache.juneau.swaps.StackTraceElementSwap

public class StackTraceElementSwap
extends ObjectSwap<StackTraceElement,String>

Transforms StackTraceElements to String objects.

The swap is identical to just calling StackTraceElement.toString(), but provides the ability to parse the resulting string back into a bean.

Method Details

swap

public String swap(BeanSession session,
 StackTraceElement o)

Converts the specified Enumeration to a List.

Overrides:

swap in class ObjectSwap<StackTraceElement,String>

Parameters:

session - The bean session to use to get the class meta. This is always going to be the same bean context that created this swap.

o - The object to be transformed.

Returns:

The transformed object.

unswap

public StackTraceElement unswap(BeanSession session,
 String in,
 ClassMeta<?> hint)

Description copied from class: ObjectSwap

If this transform is to be used to reconstitute objects that aren't true Java beans, it must implement this method.

Overrides:

unswap in class ObjectSwap<StackTraceElement,String>

Parameters:

session - The bean session to use to get the class meta. This is always going to be the same bean context that created this swap.

in - The transformed object.

hint - If possible, the parser will try to tell you the object type being created. For example, on a serialized date, this may tell you that the object being created must be of type GregorianCalendar.
This may be null if the parser cannot make this determination.

Returns:

The narrowed object.
