Class HomogeneousTablesInput

java.lang.Object
uk.ac.starlink.ttools.task.HomogeneousTablesInput
All Implemented Interfaces:
TablesInput
public class HomogeneousTablesInput extends Object implements TablesInput
TablesInput which has a variable number of input tables, treating them all the same as each other. A single, possibly repeated, parameter is used to specify any number of input tables, and a single (not repeated) filter parameter is used to specify a processing pipeline which operates identically on all the inputs.
