uk.ac.starlink.table.join.AbstractSkyMatchEngine

uk.ac.starlink.table.join.ErrorSkyMatchEngine

uk.ac.starlink.table.join.ErrorSkyMatchEngine.InDegrees

All Implemented Interfaces:

MatchEngine

Enclosing class:

ErrorSkyMatchEngine

public static class ErrorSkyMatchEngine.InDegrees
extends ErrorSkyMatchEngine

MatchEngine class that behaves like ErrorSkyMatchEngine but uses human-friendly units (degrees and arcseconds) rather than radians for tuple elements and match parameters.

Constructor Detail

InDegrees

public InDegrees(SkyPixellator pixellator,
                 ErrorSummation errorSummation,
                 double scaleRadians)

Constructor.

Parameters:

pixellator - handles sky pixellisation

errorSummation - error combination method

scaleRadians - initial value for length scale, in radians

Method Detail

getTupleInfos

public ValueInfo[] getTupleInfos()

Description copied from interface: MatchEngine

Returns a set of ValueInfo objects indicating what is required for the elements of each tuple. The length of this array is the number of elements in the tuple. Each element should at least have a defined name and content class. The info's nullable attribute has a special meaning: if true it means that it makes sense for this element of the tuple to be always blank (for instance assigned to no column).

Specified by:

getTupleInfos in interface MatchEngine

Overrides:

getTupleInfos in class ErrorSkyMatchEngine

Returns:

array of objects describing the requirements on each element of the tuples used for matching

getMatchParameters

public DescribedValue[] getMatchParameters()

Description copied from interface: MatchEngine

Returns a set of DescribedValue objects whose values can be modified to modify the matching criteria. Typically at least one of these will be some sort of tolerance separation which determines how close tuples must be to count as a match. This match engine's behaviour can be modified by calling DescribedValue.setValue(java.lang.Object) on the returned objects.

Specified by:

getMatchParameters in interface MatchEngine

Overrides:

getMatchParameters in class ErrorSkyMatchEngine

Returns:

array of described values which influence the match
