Instance Method Details

#selective_binding(*methods, &block) ⇒ Object

Creates a selective binding instance for self and returns the newly created binding:

selective_binding :attr1, :method1
#=> <#Binding>

Passing a hash as the last argument allows for setting custom attributes. These override any previously defined forwarded methods:

selective_binding :attr1 => "custom value"
#=> <#Binding>

Passing a block is also supported to set the default value for undefined attributes or methods:

selective_binding do
  "default value"
end
#=> <#Binding>
