newSliceAccessor

default SliceAccessor<T> newSliceAccessor()

Description copied from interface: Slice

An accessor which allows for 'claiming' a sub-range of this slice. The claimed range can be incrementally modified which may re-use already allocated resources (e.g. claimed pages) and thus improve performance. Sub-ranges of a slice can be loaded and iterated or inserted into. The sub-ranges can be modified dynamically.

Specified by:

newSliceAccessor in interface Slice<T>

getPageForPageId
