end

Class Method Details

.[](*namespace_values) ⇒ Object

Internal: Allows for more compact NamespaceSet creation by giving a list of namespace values.

Examples:

NamespaceSet['development', -> { ENV['HOST'] }]

Returns a new NamespaceSet

Instance Method Details

#+(other) ⇒ Object

Internal: Allows a NamespaceSet to be combined with some other array-like object.

It does not mutate the source NamespaceSet but rather creates a new one and returns it.

Examples:

# Can be an Array
namespace_set = NamespaceSet.new ['value_1', 'value_2']
namespace_set + ['value_3']
# => <NamespaceSet namespaces=['value_1', 'value_2', 'value_3']>

# Can be a Set
namespace_set = NamespaceSet.new ['value_1', 'value_2']
namespace_set + Set['value_3']
# => <NamespaceSet namespaces=['value_1', 'value_2', 'value_3']>

# Can be a object which is convertable to an Array
namespace_set = NamespaceSet.new ['value_1', 'value_2']
namespace_set + (1..3)
# => <NamespaceSet namespaces=['value_1', 'value_2', '1', '2', '3']>

Returns a NamespaceSet

def +(other)
  NamespaceSet.new namespaces + other.to_a
end

#==(other) ⇒ Object

Internal: Determines whether a NamespaceSet is equal to another array-like object.

Returns a Boolean

def ==(other)
  self.to_a.eql? other.to_a
end

#each ⇒ Object

Internal: Iterates over each namespace value and allows it to be used in a block.

  end
end

#eql?(other) ⇒ Boolean

Internal: Determines whether a NamespaceSet is equal to another NamespaceSet.

Returns a Boolean

Returns:

end

#to_ary ⇒ Object Also known as: to_a

Internal: Converts a NamespaceSet into an Array consisting of the namespace values stored in the set.

Returns an Array
