Package uk.ac.starlink.table.storage

RowStore implementations.

See: Description

Interface Summary

Interface	Description
ByteStoreAccess	Interface for random access reading for data that has been written into a byte store.
ColumnReader	Accessor for stored values.
ColumnStore	Defines an object which can store the data of a column, that is, an array of homogeneous objects.

Class Summary

Class	Description
AdaptiveByteStore	ByteStore which adopts a hybrid approach between use of memory and use of disk.
ArrayPrimitiveStore	ValueStore implementation which stores primitive values in a normal java array.
ByteStoreRowStore	RowStore based on a ByteStore.
ByteStoreStoragePolicy	Abstract StoragePolicy implementation based on a ByteStore.
Codec	Serializes and deserializes objects to/from a data stream.
ColumnStoreStarTable	StarTable implementation which retrieves its data from ColumnStore objects.
DiscardByteStore	ByteStore implementation which discards bytes.
DiscardRowStore	Minimal implementation of RowStore which throws away the row data it is given.
DiskRowStore	Implementation of RowStore which stores data on disk.
FileByteStore	ByteStore implementation which uses a temporary file.
IndexedStreamColumnStore	ColumnStore implementation which uses two streamed files to store a variable number of variable-length data items.
LimitByteStore	ByteStore wrapper class which will throw an IOException during writing if an attempt is made to store more than a fixed number of bytes.
ListRowStore	Implementation of RowStore which stores data in memory.
MemoryByteStore	ByteStore implementation which stores bytes in a buffer in memory.
MonitorStoragePolicy	Wrapper storage policy which derives its functionality from an existing ("base") policy, but additionally passes row storage events to a supplied TableSink.
NioByteStoreAccess	Partial implementation of ByteStoreAccess.
SidewaysRowStore	RowStore implementation which stores data cell data in a column-oriented fashion, so that members of the same column, rather than of the same row, are stored contiguously on disk.
StreamColumnStore	ColumnStore implementation which uses a streamed file to store a variable number of fixed-length data items.

Package uk.ac.starlink.table.storage Description

RowStore implementations. These are used by StoragePolicy objects to provide actual temporary storage for table data.
