signalNumber

public final int signalNumber

Method Detail

values

public static KillSignal[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

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

Returns:

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

valueOf

public static KillSignal 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

number

public String number()

Returns:

the number associated with this signal.

withLeadingDash

public static String withLeadingDash(String signal)

Given a signal, prepend a leading dash if necessary, e.g. change "9" into "-9".

Parameters:

signal - the signal to modify

Returns:

the possibly modified signal with a leading dash

withLeadingDash

public String withLeadingDash()

Return this signal's number with a leading dash, e.g. "-3".

Returns:

this instance of signal's number with a leading dash
