public ParquetColumnRegionFloat(@NotNull
 ColumnChunkPageStore<ATTR> columnChunkPageStore,
 @NotNull
 ParquetFormatColumnLocation<ATTR> location)

Method Details

getFloat

public float getFloat(long elementIndex)

Description copied from interface: ColumnRegionFloat

Get a single float from this region.

Specified by:

getFloat in interface ColumnRegionFloat<ATTR extends Attributes.Values>

Parameters:

elementIndex - Element (float) index in the table's address space

Returns:

The float value at the specified element (float) index

getFloat

public float getFloat(@NotNull
 ChunkSource.FillContext context,
 long elementIndex)

Description copied from interface: ColumnRegionFloat

Get a single float from this region.

Specified by:

getFloat in interface ColumnRegionFloat<ATTR extends Attributes.Values>

Parameters:

context - A ColumnRegionFillContext to enable resource caching where suitable, with current region index pointing to this region

elementIndex - Element (float) index in the table's address space

Returns:

The float value at the specified element (float) index

binSearchMatch

public Index binSearchMatch(long firstKey,
 long lastKey,
 @NotNull
 SortPair sortPair,
 @NotNull
 Object[] keys)

Description copied from interface: ColumnRegion

Given that this column is sorted, match the input keys using a binary search.

Specified by:

binSearchMatch in interface ColumnRegion<ATTR extends Attributes.Values>

Parameters:

firstKey - The first key to search

lastKey - The last key to search

sortPair - the sorting definition

keys - the keys to search for, in no particular order

couldInclude

public boolean couldInclude(@NotNull
 Object[] keys)

Description copied from interface: ColumnRegion

Check if the region could possibly include any of the keys we're searching for

Specified by:

couldInclude in interface ColumnRegion<ATTR extends Attributes.Values>

Parameters:

keys - the keys to search for

Returns:

true if the region possibly contains the values

getChunkPageContaining

ChunkPage<ATTR> getChunkPageContaining(long elementIndex)
