AbstractGridFormat

UnknownFormat

All Implemented Interfaces:

Format

public class UnknownFormat
extends AbstractGridFormat
implements Format

This class can be used when a proper Format cannot be found for some input sources.

It implements the abstract method of AbstractGridFormat but it always returns null to indicate that the format it represents is unknown.

Method Summary

Modifier and Type	Method and Description
boolean	accepts(Object input, Hints hints) Tells me if this Format can read the provided input.
