Class ConnectionRelativeTime

java.lang.Object
net.jini.core.constraint.ConnectionRelativeTime
All Implemented Interfaces:
Serializable, InvocationConstraint, RelativeTimeConstraint
public final class ConnectionRelativeTime extends Object implements RelativeTimeConstraint, Serializable
Represents a constraint on the maximum amount of time to wait for a network connection to be established. The precise meaning of this will vary across communication mechanisms, but in the typical case of Socket-based communication, the intention is that this constraint controls the timeout parameter of the connect method.

The duration is translated into an absolute end time at the point of a remote call by adding the caller's current time.

    • ConnectionRelativeTime

      public ConnectionRelativeTime(long time)
      Creates a constraint with the specified duration.
      Parameters:
      time - the maximum connection duration in milliseconds
      Throws:
      IllegalArgumentException - if the argument is less than zero

    • getTime

      public long getTime()
      Returns the maximum connection duration in milliseconds.
      Returns:
      the maximum connection duration in milliseconds

    • makeAbsolute

      public InvocationConstraint makeAbsolute(long baseTime)
      Returns a ConnectionAbsoluteTime instance with time obtained by adding the specified base time argument to the duration value from this instance. If the addition results in overflow, a time value of Long.MAX_VALUE is used.
      Specified by:
      makeAbsolute in interface RelativeTimeConstraint
      Parameters:
      baseTime - an absolute time, specified in milliseconds from midnight, January 1, 1970 UTC
      Returns:
      a constraint that has the relative times converted to absolute times by adding the specified absolute time to each relative time
