Classes

struct  ros::message_traits::DataType< M >
 Specialize to provide the datatype for a message. More...
struct  ros::message_traits::Definition< M >
 Specialize to provide the definition for a message. More...
struct  ros::message_traits::FalseType
 Base type for compile-type true/false tests. Compatible with Boost.MPL. classes inheriting from this type are false values. More...
struct  ros::message_traits::FrameId< M, Enable >
 FrameId trait. In the default implementation pointer() returns &m.header.frame_id if HasHeader<M>::value is true, otherwise returns NULL. value() does not exist, and causes a compile error. More...
struct  ros::message_traits::FrameId< M, typename boost::enable_if< HasHeader< M > >::type >
struct  ros::message_traits::HasHeader< M >
 HasHeader informs whether or not there is a header that gets serialized as the first thing in the message. More...
struct  ros::message_traits::Header< M, Enable >
 Header trait. In the default implementation pointer() returns &m.header if HasHeader<M>::value is true, otherwise returns NULL. More...
struct  ros::message_traits::Header< M, typename boost::enable_if< HasHeader< M > >::type >
struct  ros::message_traits::IsFixedSize< M >
 A fixed-size datatype is one whose size is constant, i.e. it has no variable-length arrays or strings. More...
struct  ros::message_traits::IsMessage< M >
 Am I message or not. More...
struct  ros::message_traits::IsSimple< M >
 A simple datatype is one that can be memcpy'd directly in array form, i.e. it's a POD, fixed-size type and sizeof(M) == sum(serializationLength(M:a...)) More...
struct  ros::message_traits::MD5Sum< M >
 Specialize to provide the md5sum for a message. More...
struct  ros::message_traits::TimeStamp< M, Enable >
 TimeStamp trait. In the default implementation pointer() returns &m.header.stamp if HasHeader<M>::value is true, otherwise returns NULL. value() does not exist, and causes a compile error. More...
struct  ros::message_traits::TimeStamp< M, typename boost::enable_if< HasHeader< M > >::type >
struct  ros::message_traits::TrueType
 Base type for compile-type true/false tests. Compatible with Boost.MPL. classes inheriting from this type are true values. More...
