Package uk.ac.starlink.ttools.cone

Interface Summary

Interface	Description
BlockUploader.BlockStats	Provides information about a match.
ColumnPlan	Describes the arrangement of columns in the output table based on the columns in the upload and raw result tables.
ConeQueryRowSequence	RowSequence sub-interface which additionally defines methods for retrieving RA, Dec search radius and row index for each row.
Coner	Defines a service which can perform cone search-like operations.
ConeResultRowSequence	ConeQueryRowSequence sub-interface which additionally defines a method for retrieving the result of the cone search itself.
ConeSearcher	Object which can perform repeated sky cone searches.
Coverage	Defines coverage of a sky positional search service.
MocFormat	Defines a MOC serialization format.
QuerySequenceFactory	Object which can generate an iterator over cone search specifiers.
RowMapper<I>	Defines a mapping between objects of some given type and table row index.
SkyTiling	Defines a pixellation scheme which maps sky positions to long integers.
UploadMatcher	Defines a service that can perform sky position crossmatches by taking a sequence of cone-like positions for input and submitting them as a block to a remote execution matching service.

Class Summary

Class	Description
AngleUnits	Defines a unit of angle measurement.
AsciiMocCoverage	MOC coverage implementation which uses the ASCII serialization.
BlockUploader	Works with an UploadMatcher dividing the input table into chunks and uploading them separately to produce an arbitrarily large result while each upload/match operation is of a limited size.
CdsHealpix	Healpix implementation for use with the MOC library based on F-X Pineau's cds-healpix-java library.
CdsHealpixUtil	Utilities for working with the cds-healpix-java library in sky plots.
CdsUploadMatcher	UploadMatcher implementation for the CDS Xmatch service.
CdsUploadMatcher.VizierMeta	Metadata provided for Vizier tables by the CDS Xmatch service.
ColumnQueryRowSequence	ConeQueryRowSequence implementation which extracts values based on supplied column indices.
ConeErrorPolicy	Defines how errors are treated during a multiple cone search operation.
ConeErrorPolicyParameter	Parameter for selecting ConeErrorPolicy objects.
ConeMatcher	TableProducer which does the work for a multiple cone search-type sky crossmatch operation.
ConeMatcher.ConeWorker	Object which produces the result table.
ConeQueryCoverage	Coverage implementation giving the area defined by a sequence of positional (cone search-like) queries.
ConeSearchConer	Coner implementation which uses remote Cone Search services or similar.
ConeSelector	Abstract class for an object which can make a JDBC SELECT query corresponding to cone searches.
ConeServiceType	Characterises a simple DAL service based on sky position.
CoverageQuerySequenceFactory	Wrapper QuerySequenceFactory that filters out elements outside of a given coverage object.
DalConeSearcher	Utility class to aid with implementation of ConeSearcher classes based on contact with remote Data Access Layer-type services.
HealpixSortedQuerySequenceFactory	QuerySequenceFactory that presorts rows according to HEALPix pixel index.
HealpixTiling	Tiling implementation based on the HEALPix scheme.
HtmTiling	HTM implementation of SkyTiling.
JdbcConer	Coner implementation which works by performing SELECT statements over a JDBC database connection.
JdbcConeSearcher	ConeSearcher implementation using JDBC access to an SQL database.
JELQuerySequenceFactory	QuerySequenceFactory which uses JEL expressions for RA, Dec and SR.
LimitRowSink	TableSink wrapper implementation that truncates the row stream at a given maximum.
MocCoverage	Abstract superclass for Coverage implementations based on MOC (HEALPix Multi-Order Coverage) objects.
ParallelResultRowSequence	ConeResultRowSequence implementation which uses a fixed number of worker threads to dispatch cone queries in parallel.
SequentialResultRowSequence	Straightforward implementation of ConeResultRowSequence based on a ConeQueryRowSequence.
ServiceConeSearcher	ConeSearcher implementation using a VO Cone Search service.
SiaConeSearcher	ConeSearcher implementation using a VO Simple Image Access service.
SkyBox	Defines a region of the celestial sphere which is rectangular in Right Ascension and Declination coordinates.
SkyConeMatch2	Crossmatcher which works by performing one cone-search type query for each row of an input table on an external service of some kind.
SsaConeSearcher	ConeSearcher implementation using a VO Simple Spectral Access service.
TapUploadMatcher	UploadMatcher implementation for a TAP service.
TilingParameter	Parameter for specifying SkyTiling values.
UploadConeTable	Table suitable for uploading based on a sequence of positional queries and an RowMapper.
UrlMocCoverage	MOC coverage implementation which reads a MOC from a given URL.
WrapperQuerySequence	ConeQueryRowSequence implementation which delegates all methods to a supplied instance.
