Constructor Detail

CoordValue

public CoordValue(Coord coord,
                  String[] exprs,
                  DomainMapper[] dms)

Constructor.

Parameters:

coord - coordinate definition

exprs - array of user-supplied expressions, one for each input value associated with the coordinate

dms - array of DomainMappers, one for each input value; individual elements may be null if no DomainMapper is known

Method Detail

getCoord

public Coord getCoord()

Returns the coordinate definition.

Returns:

coord

getExpressions

public String[] getExpressions()

Returns the user-supplied expressions for the coordinate's values.

The returned array has coord.getInputs().length elements.

Returns:

expressions array

getDomainMappers

public DomainMapper[] getDomainMappers()

Returns the domain mappers used to decode the coordinate's input values, where known. Note that individual elements may be null if the domain mapper is not known; in this case downstream code will need to come up with a plausible value.

The returned array has coord.getInputs().length elements.

Returns:

domain mapper array
