#==(other)
(also: #eql?)
Is
other
equal to this platform? Two platforms are equal if they have the same CPU, OS and version. -
#===(other)
Does
other
match this platform? Two platforms match if they have the same CPU, or either has a CPU of 'universal', they have the same OS, and they have the same version, or either has no version. -
#=~(other)
Does
other
match this platform? Ifother
is a String it will be converted to aPlatform
first. -

Instance Method Details
#==(other) Also known as: #eql?
Is other
equal to this platform? Two platforms are equal if they have the same CPU, OS and version.
#===(other)
Does other
match this platform? Two platforms match if they have the same CPU, or either has a CPU of 'universal', they have the same OS, and they have the same version, or either has no version.
Additionally, the platform will match if the local CPU is 'arm' and the other CPU starts with “arm” (for generic ARM family support).

def ===(other) return nil unless Gem::Platform === other # cpu ([nil,'universal'].include?(@cpu) or [nil, 'universal'].include?(other.cpu) or @cpu == other.cpu or (@cpu == 'arm' and other.cpu =~ /\Aarm/)) and # os @os == other.os and # version (@version.nil? or other.version.nil? or @version == other.version) end
#=~(other)
Does other
match this platform? If other
is a String it will be converted to a Platform
first. See #=== for matching rules.
