public interface RelativeTimeConstraint
extends InvocationConstraint

Implemented by constraints that are expressed in terms of relative time, to support conversion to absolute time constraints.

Method Summary

InvocationConstraint

makeAbsolute(long baseTime) Converts this constraint to absolute time.

Method Detail

makeAbsolute

InvocationConstraint makeAbsolute(long baseTime)

Converts this constraint to absolute time. Takes an absolute time, specified in milliseconds from midnight, January 1, 1970 UTC, and returns a constraint that has the same information content as this constraint except that the relative times have been converted to absolute times by adding the specified absolute time to each relative time in this constraint. If the addition results in underflow or overflow, a time value of Long.MIN_VALUE or Long.MAX_VALUE is used, respectively. The returned constraint will typically be an instance of a different constraint class than this constraint.

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
