Method Details

values

public static KillSignal[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static KillSignal valueOf(String 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()
