Class SimplifiedIntervalList.SkippingIntervalPredicate

java.lang.Object

com.yahoo.bard.webservice.util.SimplifiedIntervalList.SkippingIntervalPredicate

All Implemented Interfaces:

Predicate<org.joda.time.Interval>

Direct Known Subclasses:

SimplifiedIntervalList.IsSubinterval

Enclosing class:

SimplifiedIntervalList

public static class SimplifiedIntervalList.SkippingIntervalPredicate
extends Object
implements Predicate<org.joda.time.Interval>

A predicate to scan a Simplified Interval List using an iterator and a test predicate. An iterator over the list is scanned until an interval not fully before the interval under test is found. If no such interval exists, a default value is returned. This predicate can be reused as long as each subsequent call to the test has an equal or later start date.

Constructor and Description
SkippingIntervalPredicate(SimplifiedIntervalList supplyList, BiPredicate<org.joda.time.Interval,org.joda.time.Interval> testPredicate, boolean defaultValue) Constructor to build a predicate that applies an arbitrary predicate to not-before intervals from the iterator.

Method Summary

Modifier and Type	Method and Description
boolean	test(org.joda.time.Interval testInterval) Skip through the supply intervals until an active interval matches (that is, one which is at or after the test interval) is located and then test it against the testPredicate.

Constructor Detail

SkippingIntervalPredicate

public SkippingIntervalPredicate(SimplifiedIntervalList supplyList,
                                 BiPredicate<org.joda.time.Interval,org.joda.time.Interval> testPredicate,
                                 boolean defaultValue)

Constructor to build a predicate that applies an arbitrary predicate to not-before intervals from the iterator.

Parameters:

supplyList - The SimplifiedList of intervals to test the predicate against

testPredicate - The predicate to use when testing an interval against the supply

defaultValue - The value for the test if no comparison interval can be found in the list.

Method Detail

test

public boolean test(org.joda.time.Interval testInterval)

Skip through the supply intervals until an active interval matches (that is, one which is at or after the test interval) is located and then test it against the testPredicate. If no comparison interval is found, return a default value.

Specified by:

test in interface Predicate<org.joda.time.Interval>

Parameters:

testInterval - The interval to test against an active interval

Returns:

the result of the test predicate with an active interval otherwise default value
