All Implemented Interfaces:

AutoCloseable

ScrubIterator

Enclosing class:

PartitionIndex

public static class PartitionIndex.IndexPosIterator
extends ValueIterator<PartitionIndex.IndexPosIterator>

Iterator of index positions covered between two keys. Since we store prefixes only, the first and last returned values can be outside the span (and inclusiveness is not given as we cannot verify it).

Constructor Details

IndexPosIterator

public IndexPosIterator(PartitionIndex index)

Parameters:

index - PartitionIndex to use for the iteration.

Note: For performance reasons this class does not keep a reference of the index. Caller must ensure a reference is held for the lifetime of this object.

Method Details

nextIndexPos

protected long nextIndexPos()

Returns the position in the row index or data file.
