+//A buffer is a linear, finite sequence of elements of a specific primitive type. Aside from its content,
+//the essential properties of a buffer are its capacity, limit, and position:
+//
+//A buffer's capacity is the number of elements it contains. The capacity of a buffer is never negative and never changes.
+//
+//A buffer's limit is the index of the first element that should not be read or written.
+//A buffer's limit is never negative and is never greater than its capacity.
+//
+//A buffer's position is the index of the next element to be read or written.
+//A buffer's position is never negative and is never greater than its limit.
