Initialize a new namespace.

Signature

parameter　registry　Registry: The underlying registry.
parameter　name　Symbol: The namespace name.

Implementation

def initialize(registry, name)
	@registry = registry
	@name = name.to_sym
end

`attr :registry`

Signature

attribute　Registry: The underlying registry.

`attr :name`

Signature

attribute　Symbol: The namespace name.

`def metric(name)`

Get a metric in this namespace.

Signature

parameter　name　Symbol: The metric name.
returns　Metric: A metric instance for the namespaced field.

Implementation

def metric(name)
	@registry.metric(metric_name(name))
end

`def namespace(name)`

Get a nested namespace.

Signature

parameter　name　Symbol: The nested namespace name.
returns　Namespace: A namespace view with the composed name.

Implementation

def namespace(name)
	self.class.new(@registry, metric_name(name))
end
