All Implemented Interfaces:

FormatStrategy<Vector<T>>, ParseStrategy<Vector<T>>

public class VectorOption<T>
extends Option<Vector<T>>

Abstract class defining behavior shared by all configuration options with values of type Vector. VectorOption now allows empty strings, i.e. "[,]" is a vector of two empty strings. "[]" will be interpreted as a vector of one empty string, and "" is an empty vector.

Method Detail

parse

public Vector<T> parse(String s)

Description copied from class: OptionParser

The ability to parse a string to an object of type T. All concrete versions of this class must override this method to provide some sort of parser implementation.

Specified by:

parse in interface ParseStrategy<Vector<T>>

Specified by:

parse in class OptionParser<Vector<T>>

Parameters:

s - The String to be parsed.

Returns:

An instance of Vector represented by "s".

Throws:

IllegalArgumentException - if "s" is not formatted according to the method Vector.toString().

format

public String format(Vector<T> v)

Formats the Vector v. The overall String format is determined by the method Vector.tString(), but each element of the vector is formatted by calling formatElement().

Specified by:

format in interface FormatStrategy<Vector<T>>

Overrides:

format in class Option<Vector<T>>

Parameters:

v - The Vector to be formatted.

Returns:

A String representing "v".
