Detailed Description

template<typename M>
class message_filters::UpdateFilter< M >

Filters consecutive messages with the same timestamp. Only the first message passes, all consecutive are dropped. It is templated on the message type to be filtered.

message_filters::Subscriber sub<MsgStamped>(nh, TOPIC_NAME, 1);
message_filters::UpdateFilter filter<MsgStamped>(&sub));

// Register all callback receiving filtered output
filter.registerCallback(&filteredCallback);
