##
# A VendorSet represents gems that have been unpacked into a specific
# directory that contains a gemspec.
#
# This is used for gem dependency file support.
#
# Example:
#
# set = Gem::DependencyResolver::VendorSet.new
#
# set.add_vendor_gem 'rake', 'vendor/rake'
#
# The directory vendor/rake must contain an unpacked rake gem along with a
# rake.gemspec (watching the given name).
class Gem::DependencyResolver::VendorSet
def initialize
@specs = {}
end
##
# Adds a specification to the set with the given +name+ which has been
# unpacked into the given +directory+.
def add_vendor_gem name, directory
gemspec = File.join directory, "#{name}.gemspec"
spec = Gem::Specification.load gemspec
key = "#{spec.name}-#{spec.version}-#{spec.platform}"
@specs[key] = spec
end
##
# Returns an Array of VendorSpecification objects matching the
# DependencyRequest +req+.
def find_all req
@specs.values.select do |spec|
req.matches_spec? spec
end.map do |spec|
Gem::DependencyResolver::VendorSpecification.new self, spec, nil
end
end
##
# Loads a spec with the given +name+, +version+ and +platform+. Since the
# +source+ is defined when the specification was added to index it is not
# used.
def load_spec name, version, platform, source
key = "#{name}-#{version}-#{platform}"
@specs.fetch key
end
##
# No prefetch is needed as the index is loaded at creation time.
