Method Detail

convertImpl

protected java.lang.Object convertImpl(java.lang.Class destinationClass,
                                       java.lang.Object source,
                                       java.util.Locale locale)
                                throws java.lang.Exception
The implementation of the convert method, which may omit the invalid argument checks already performed by this base class. By default, this method creates a new instance of the destinationClass and copies information from the source to the destination. This implementation should be fine as-is for Copiers, but Converters will need to implement this method since they will not be implementing the copy method.

Overrides:
convertImpl in class BaseTransformer
locale - the locale in which the conversion should take place. for converters that are not locale-aware, the local argument can simply be ignored
Throws:
java.lang.Exception

getSourceClassesImpl

protected java.lang.Class[] getSourceClassesImpl()
                                          throws java.lang.Exception
Transformer.getSourceClasses() implementation template method.

Specified by:
getSourceClassesImpl in class BaseTransformer
Returns:
Class[]
Throws:
java.lang.Exception

getDestinationClassesImpl

protected java.lang.Class[] getDestinationClassesImpl()
                                               throws java.lang.Exception
Transformer.getDestinationClasses() implementation template method.

Specified by:
getDestinationClassesImpl in class BaseTransformer
Returns:
Class[]
Throws:
java.lang.Exception

isWrappingRuntimeExceptions

protected boolean isWrappingRuntimeExceptions()
Indicates whether runtime exceptions should be wrapped as TransformationExceptions. By default, this method returns true.

Simple transformers in Morph that operate on JDK types like Numbers and Strings will usually set this value to true so that they throw TransformationExceptions if problems occur. More complex transformers that operate on graphs of objects are encouraged to set this value to false so that runtime exceptions are not wrapped. This way, problems accessing data will be expressed by the native API of a user's domain objects and avoid the need to catch Morph-specific exceptions (assuming the use of runtime exceptions in said domain objects).

Overrides:
isWrappingRuntimeExceptions in class BaseTransformer
Returns:
true
