Class Time

java.lang.Object
  org.ros.message.Time

All Implemented Interfaces:

java.lang.Comparable<Time>

public class Time
extends java.lang.Object
implements java.lang.Comparable<Time>

ROS Time representation. Time and Time are primitive types in ROS. ROS represents each as two 32-bit integers: seconds and nanoseconds since epoch.

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Check for equality between Time objects.

This method does not normalize Time representations, so fields must match exactly.
