Signal
The Kanrisuru::Util::Signal class is a lookup utility module that helps with translating and validating a signal from int to string representation. This lookup table currently supports linux signals.
Public Class Methods
[]
Lookup the opposing value of a signal. If the value is an integer, it will return a string; if the value is a string, it will return an integer.
Kanrisuru::Util::Signal['KILL']
9
Kanrisuru::Util::Signal[9]
'KILL'
valid?
Check if the signal exists in the lookup table.
Kanrisuru::Util::Signal.valid?('HUP')
true
Kanrisuru::Util::Signal.valid?(1)
true
Kanrisuru::Util::Signal.valid?('SIGHUP')
true
Kanrisuru::Util::Signal.valid?('')
false
Lookup Table
Has two lookup tables, @linux and @linux_inverted. Both created for quick in-memory lookup of signal translations.
