Class Method Details

.call(value) ⇒ Integer

Return the string length

Examples:

length = Length.call(value)

Parameters:

• value (String)

Returns:

• (Integer)

# File 'lib/axiom/function/string/length.rb', line 21

def self.call(value)
  value.length
end

.type ⇒ Class<Types::Integer>

Return the type returned from #call

Examples:

type = Axiom::Function::String.type  # => Axiom::Types::Integer

Returns:

• (Class<Types::Integer>)

# File 'lib/axiom/function/string/length.rb', line 33

def self.type
  Types::Integer
