Method Detail

createIterator
protected java.util.Iterator<Resource> createIterator()
Description copied from class:AbstractResourceCollectionWrapper
Do 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:
createIterator
in classAbstractResourceCollectionWrapper
- Returns:
- the iterator on the resource collection
-
getSize
protected int getSize()
Description copied from class:AbstractResourceCollectionWrapper
Do compute the size of the resource collection. The implementation of this function is allowed to be not thread safe.- Specified by:
getSize
in classAbstractResourceCollectionWrapper
- Returns:
- size of resource collection.
-
filterResource
protected boolean filterResource(Resource r)
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
