Gets all methods for a class (taking class heirarchy into account)- Parameters:
clazz
- The class to analyze for all methods- Returns:
- The set of all methods on this class (and all subclasses)
-
createMethodWrapper
MethodWrapper createMethodWrapper(Method m)

m
- A non-null method to create a wrapper from- Returns:
- A method wrapper
-
getAllFields
Set<Field> getAllFields(Class<?> clazz)
Gets all fields for a class (taking class heirarchy into account)- Parameters:
clazz
- The class to analyze for all fields- Returns:
- The set of all fields on this class (and all subclasses)
-
findPostConstruct
Method findPostConstruct(Class<?> clazz, Class<?> matchingClass) throws IllegalArgumentException
Finds the postConstruct method on this class- Parameters:
clazz
- The class to check for the postConstruct methodmatchingClass
- The PostConstruct interface, a small performance improvement- Returns:
- A matching method, or null if none can be found

-
findPreDestroy
Method findPreDestroy(Class<?> clazz, Class<?> matchingClass) throws IllegalArgumentException
Finds the preDestroy method on this class- Parameters:
clazz
- The class to check for the postConstruct methodmatchingClass
- The PostConstruct interface, a small performance improvement- Returns:
- A matching method, or null if none can be found
- Throws:
IllegalArgumentException
- If a method marked as postConstruct is invalid
-
clean
void clean(Class<?> clazz)
Removes this class (and all appropriate sub-classes) from the cache- Parameters:
clazz
- The class to remove. If null this method does nothing
-
dispose
void dispose()
Releases the entire cache, though the ClassReflectionHelper is still usable after calling dispose
-
size
