Interface Summary

Predicate.Annotations
SampleIndex.Annotations	Known annotations.
SampleIndex.IOffsetSampler	Interface for obtaining an array of tuple offsets to be sampled.

Class Summary

Predicate<E>	A generic implementation of an immutable IPredicate.
SampleIndex<E>	Sampling operator for the IAccessPath implied by an IPredicate.
SampleIndex.AcceptanceSetOffsetSampler	An implementation based on an acceptance set of offsets which have been accepted.
SampleIndex.AccessPathSample<E>	A sample from an access path.
SampleIndex.BitVectorOffsetSampler	Return a randomly selected ordered array of offsets in the given half-open range.
SampleIndex.EntireRangeOffsetSampler	Returns all offsets in the half-open range, but may only be used when the limit GTE the range count.
SampleIndex.SmartOffsetSampler	A smart implementation which uses whichever implementation is most efficient for the limit and key range to be sampled.

Enum Summary

SampleIndex.SampleType

Typesafe enumeration of different kinds of index sampling strategies.
