Interface WcOptions

All Superinterfaces:

Iterable<WcOption>, OptionSet<WcOption>

All Known Implementing Classes:

WcOption, WcOptions.Default, WcOptionSet_lmw

public interface WcOptions
extends OptionSet<WcOption>

Interface implemented by all option sets for the wc command. It is recommended to use Wc.Options to specify a valid combination of options.

The options for the wc command are:

	-l		--lines		Executes a count of lines and writes this count to the output.
	-w		--words		Executes a count of words and writes this count to the output. A word is a non-zero-length string of characters delimited by white space as defined by Character.isWhitespace(char).
	-m		--chars		Executes a count of chars and writes this count to the output.

This interface serves as an alias for the extended interface to simplify the command signature methods by avoiding generic parameters.
