createIterator
Description copied from class:AbstractResourceCollectionWrapperDo create an iterator on the resource collection. The creation of the iterator is allowed to not be thread safe whereas the iterator itself should. The returned iterator will be wrapped into the FailFast one.- Specified by:
createIteratorin classAbstractResourceCollectionWrapper- Returns:
- the iterator on the resource collection
-
getSize
protected int getSize()Description copied from class:AbstractResourceCollectionWrapperDo compute the size of the resource collection. The implementation of this function is allowed to be not thread safe.- Specified by:
getSizein classAbstractResourceCollectionWrapper- Returns:
- size of resource collection.
-
filterResource
Specify if the resource should be filtered or not. This function should be overridden in order to define the filtering algorithm- Parameters:
r- resource considered for filtration- Returns:
- whether the resource should be filtered or not
