Enum CutOption

java.lang.Object

java.lang.Enum<CutOption>

org.unix4j.unix.cut.CutOption

All Implemented Interfaces:

Serializable, Comparable<CutOption>, Iterable<CutOption>, Option, OptionSet<CutOption>, CutOptions

public enum CutOption
extends Enum<CutOption>
implements Option, CutOptions

Options for the cut command.

For most applications, it may be more convenient to use Cut.Options instead of the option constants defined here.

	-c		--chars		The list specifies character positions.
	-f		--fields		The list specifies fields, separated in the input by the field delimiter character (see the -d option.) Output fields are separated by a single occurrence of the field delimiter character.

for (CutOption c : CutOption.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CutOption valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
