java.util.AbstractCollection<E>
java.util.AbstractList<T>
org.eclipse.jgit.util.BlockList<T>
- Type Parameters:
T
- type of list element.
- All Implemented Interfaces:
Iterable<T>
,Collection<T>
,List<T>
Random access list that allocates entries in blocks.
Unlike ArrayList
, this type does not need to reallocate the
internal array in order to expand the capacity of the list. Access to any
element is constant time, but requires two array lookups instead of one.
To handle common usages, add(Object)
and iterator()
use
internal code paths to amortize out the second array lookup, making addition
and simple iteration closer to one array operation per element processed.
Similar to ArrayList
, adding or removing from any position except the
end of the list requires O(N) time to copy all elements between the
modification point and the end of the list. Applications are strongly
encouraged to not use this access pattern with this list implementation.
