All Implemented Interfaces:

public class PojoPathCreationException
extends PojoPathException

A PojoPathCreationException is thrown by the PojoPathNavigator if the supplied mode is PojoPathMode.CREATE_IF_NULL and an intermediate Pojo was null but could NOT be created.
This can happen because the instantiation failed or there is insufficient information about what to create (e.g. the current object is a Map was NOT accessed via an generic method signature).

Since:

1.1.0

                                 Object initialPojo,
                                 String pojoPath)

Method Detail

getCode

public String getCode()

This method gets the code that identifies the detailed type of this object. While UUID or ID are typically unique per instance of an object the code is unique for all instances of the exact same kind. So e.g. a particular kind of exception or ValidationFailure can be identified by its code. A simple generic implementation may return the classname or the key of the NLS message. However, the code should remain stable after refactoring (so at least after the rename the previous code should be returned as String literal). This code may be used as a compact identifier to reference the related problem or information as well as for automatic tests of error situations that should remain stable even if the message text gets improved or the locale is unknown.

Specified by:

getCode in interface AttributeReadMessageCode

Overrides:

getCode in class NlsRuntimeException

Returns:

the message text.
