Class ConnectionRelativeTime

java.lang.Object
  extended by 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.

Constructor Detail

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
Method Detail

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

hashCode

public int hashCode()
Returns a hash code value for this object.

Overrides:
hashCode in class Object

equals

public boolean equals(Object obj)
Two instances of this class are equal if both have the same duration.

Overrides:
equals in class Object

toString

public String toString()
Returns a string representation of this object.

Overrides:
toString in class Object
