class Typelib::Registry

Public Class Methods

base_rtt_type?(type) click to toggle source

Returns true if type is handled by the typekit that is included in the RTT itself, and false otherwise.

This is used in property bags and in the interface definition, as – among the simple types – only these can be used directly in interfaces.

# File lib/orogen/typenames.rb, line 126
def self.base_rtt_type?(type)
    if type.name == "/std/string"
        return true
    elsif !(type <= Typelib::NumericType)
        return false
    end

    if type.integer?
        type.name == "/bool" || type.size == 4
    else
        type.name == "/double"
    end
end

rtt_typename(type) click to toggle source

Returns the typename used by RTT to register the given type
