Interface Summary

Interface	Description
CachedColumn	Defines storage for a vector of data.
CachedColumnFactory	Defines a capability for storing vectors of typed data.
CachedReader	Accessor for stored values.
Coord	Defines a coordinate quantity in terms of both the user's view of it and its representation for use in plotting.
CoordSpec.Reader	Reads a data value object.
DataSpec	Defines the table-like data that is required for a certain plot.
DataStore	Contains all the actual data required for a plot.
DataStoreFactory	Provides a data-bearing object capable of providing the actual data for a number of data specifications.
MaskSpec.Reader	Reads a flag.
Tuple	Defines a tuple of typed values for plotting.
TupleSequence	Interface for iterating over points to plot.
UserDataReader	Reader that can interrogate a RowData to return the coordinate and mask values specified by a DataSpec.

Class Summary

Class	Description
AbortTupleSequence	Wrapping TupleSequence that tries to give up when a condition becomes true.
AbstractDataSpec	Abstract superclass for DataSpec implementations.
AreaCoord<DG extends DataGeom>	Coord implementation for Area (shape) values.
BooleanCoord	Coord implementation for single boolean values.
ByteStoreColumnFactory	ColumnFactory that stores column data in ByteStores.
CachedDataStoreFactory	DataStoreFactory implementation that reads columns and caches them for later use.
CachedTupleSequence	TupleSequence implementation based on CachedColumns.
ColumnStorage	Arranges for storage of column data (arrays of typed values) in byte buffers.
CoordGroup	Expresses the content of a set of coordinates used for a plot layer, and how to find the values of these coordinates from a corresponding DataSpec.
CoordSpec	Characterises information about a coordinate value.
DiskCache	Represents a persistent cache based on named files in a given directory of a filesystem.
FixedLengthVectorCoord	Coord implementation for a fixed-length array of values.
FixedLengthVectorCoord.VectorDomain	Domain for use with FixedLengthVectorCoord.
FloatingArrayCoord	Coord implementation for a variable-length array of floating point values.
FloatingArrayCoord.ArrayDomain	Domain for numeric array values.
FloatingCoord	Coord implementation for floating point values.
Input	Characterises a coordinate value as specified by the user.
InputMeta	Contains user-directed metadata to describe user-supplied input data coordinate values used for plots.
IntegerCoord	Coord implementation for integer values.
LongCoord	Coord implementation for long values.
MaskSpec	Characterises information about a data inclusion mask.
MemoryColumnFactory	CachedColumnFactory implementation that stores data in arrays in memory.
MoveFileByteStore	ByteStore that stores data in a named file which appears completely populated in the filesystem.
PersistentDataStoreFactory	DataStoreFactory implementation that will store cached columns in the file system.
SimpleDataStoreFactory	DataStoreFactory implementation that does no caching.
SimpleDomain<T>	Minimal Domain implementation with only one mapper.
SimpleDomain.Mapper<T>	Simple mapper implementation.
SingleCoord	Partial Coord implementation for quantities that are represented as scalars both to the user and internally.
SkyCoord	Coord implementation for sky positions.
SkyCoord.SkyVariant	Controls the interpretation of sky vectors, either fixed to the surface of the unit sphere or not.
SmartColumnFactory	CachedColumnFactory implementation that is able to spot non-varying columns and represent them efficiently.
StepDataStore	Wrapper data store implementation that dispenses all column data as evenly spaced subsamples by row.
StringCoord	Coord implementation for String values.
TableCachedData	Supplies selected mask and coordinate data relating to a single table.
TupleRunner	SplitRunner subclass for use with TupleSequences.
WrapperDataStoreFactory	DataStoreFactory implementation which allows decoration of the tables used to obtain the data, by providing a custom wrapper for their RowSequence objects.
WrapperTuple	Tuple implementation that delegates all methods to a base instance.

Enum Summary

Enum	Description
