Method Details

length

public long length()

Specified by:

length in interface Page<Attributes.DictionaryKeys>

Returns:

the length of this page.

mask

public long mask()

Description copied from interface: PagingChunkSource

This mask is applied to OrderedKeys which are passed into ChunkSource.getChunk(ChunkSource.GetContext, OrderedKeys) and ChunkSource.fillChunk(ChunkSource.FillContext, WritableChunk, OrderedKeys). This allows the PagingChunkSources to be cached, and reused even if they are properly relocated in key space.

Specified by:

mask in interface ColumnRegion<Attributes.DictionaryKeys>

Specified by:

mask in interface PagingChunkSource<Attributes.DictionaryKeys>

Returns:

the mask for this page, which must be a bitmask representing the some number of lower order bits of a long.

getLong

public long getLong(long elementIndex)

Description copied from interface: ColumnRegionLong

Get a single long from this region.

Specified by:

getLong in interface ColumnRegionLong<Attributes.DictionaryKeys>

Parameters:

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

Returns:

The long value at the specified element (long) index

getLong

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

Description copied from interface: ColumnRegionLong

Get a single long from this region.

Specified by:

getLong in interface ColumnRegionLong<Attributes.DictionaryKeys>

Parameters:

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

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

Returns:

The long value at the specified element (long) index

fillChunkAppend

public void fillChunkAppend(@NotNull
 ChunkSource.FillContext context,
 @NotNull
 WritableChunk<? super Attributes.DictionaryKeys> destination,
 @NotNull
 OrderedKeys rowSequence)

Description copied from interface: Page.WithDefaults

Appends the values referenced by orderKeys onto destination. orderKeys are assumed to be entirely contained on this Page.

Specified by:

fillChunkAppend in interface Page.WithDefaults<Attributes.DictionaryKeys>

getLocation

public ColumnLocation getLocation()

Specified by:

getLocation in interface ColumnRegion<Attributes.DictionaryKeys>

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<Attributes.DictionaryKeys>

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<Attributes.DictionaryKeys>

Parameters:

keys - the keys to search for

Returns:

true if the region possibly contains the values

chunkMatch

public Index chunkMatch(long regionFirstKey,
 @NotNull
 OrderedKeys keysToFilter,
 boolean caseInsensitive,
 boolean invertMatch,
 @NotNull
 Object[] keys)

Specified by:

chunkMatch in interface ColumnRegion<Attributes.DictionaryKeys>
