Constructor Details

StaticPageStore

public StaticPageStore(@NotNull
 @NotNull RegionedPageStore.Parameters parameters,
 @NotNull
 @NotNull ColumnRegionByte<ATTR>[] regions)

Method Details

invalidate

public void invalidate()

Description copied from interface: ColumnRegion

Invalidate the region -- any further reads that cannot be completed consistently and correctly will fail.

Specified by:

invalidate in interface ColumnRegion<ATTR extends Any>

getByte

public byte getByte(long elementIndex)

Description copied from interface: ColumnRegionByte

Get a single byte from this region.

Specified by:

getByte in interface ColumnRegionByte<ATTR extends Any>

Parameters:

elementIndex - Element row key in the table's address space

Returns:

The byte value at the specified element row key

getByte

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

Description copied from interface: ColumnRegionByte

Get a single byte from this region.

Specified by:

getByte in interface ColumnRegionByte<ATTR extends Any>

Parameters:

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

elementIndex - Element row key in the table's address space

Returns:

The byte value at the specified element row ket

getBytes

public byte[] getBytes(long firstElementIndex,
 @NotNull
 @org.jetbrains.annotations.NotNull byte[] destination,
 int destinationOffset,
 int length)

Description copied from interface: ColumnRegionByte

Get a range of bytes from this region. Implementations are not required to verify that the range specified is meaningful.

Specified by:

getBytes in interface ColumnRegionByte<ATTR extends Any>

Parameters:

firstElementIndex - First element row keyt in the table's address space

destination - Array to store results

destinationOffset - Offset into destination to begin storing at

length - Number of bytes to get

Returns:

destination, to enable method chaining
