Method Detail
asList
asList() : List
Convert the iterator into a list. After this conversion the iterator is empty and hasNext() will always return false. Note: This method should be used with care. For example a large database result is pulled into memory completely with this method and can cause an OutOfMemory situation.
Returns:
the iterator as a list.

asList
asList(start : Number, size : Number) : List
Converts a sub-sequence within the iterator into a list. Note: This method should be used with care. For example a large database result is pulled into memory completely with this method and can cause an OutOfMemory situation.
Parameters:
start - the number of elements to iterate before adding elements to the sublist. Negative values are treated as 0.
size - the maximum number of elements to add to the sublist. Nonpositive values always result in empty list.
Returns:
a sub-sequence within the iterator into a list.

hasNext
hasNext() : boolean
Indicates if there are more elements.
Returns:
true if there are more elements, false otherwise.

next
next() : Object
Returns the next element from the Iterator.
Returns:
the next element from the Iterator.
