public interface TransactionAttributeSource
TransactionInterceptor for metadata retrieval.
 Implementations know how to source transaction attributes, whether from configuration, metadata attributes at source level (such as Java 5 annotations), or anywhere else.

 If this method returns false, the methods on the given class
 will not get traversed for getTransactionAttribute(java.lang.reflect.Method, java.lang.Class<?>) introspection.
 Returning false is therefore an optimization for non-affected
 classes, whereas true simply means that the class needs to get
 fully introspected for each method on the given class individually.
