java.lang.Object

com.day.cq.search.eval.AbstractPredicateEvaluator

com.day.cq.search.eval.RelativeDateRangePredicateEvaluator

All Implemented Interfaces:

PredicateEvaluator

public class RelativeDateRangePredicateEvaluator
extends DateRangePredicateEvaluator

RelativeDateRangePredicateEvaluator is an extension of the DateRangePredicateEvaluator that does not use absolute UNIX timestamps for lowerBound and upperBound, but relative offsets to the current server time. If you only specify either one, the default value will be 0, indicating now.

It also supports the bugzilla syntax 1s 2m 3h 4d 5w 6M 7y (one second, two minutes, three hours, four days, five weeks, 6 months, 7 years). It does not take leap years into consideration and all months are 30 days.

Note: Does not implement filtering, which means this predicate cannot be used together with filter-only predicates in an OR group.

upperBound=3600000

In the next hour

lowerBound=-86400000

In the last day

lowerBound=86400000, upperBound=172800000

The day after tomorrow

getXPathExpression

public java.lang.String getXPathExpression(Predicate p,
                                           EvaluationContext context)

Description copied from class: AbstractPredicateEvaluator

Default implementation that always returns null, ie. adds nothing to the XPath query. Subclasses can choose whether they want to implement this method or use the AbstractPredicateEvaluator.includes(Predicate, Row, EvaluationContext) method for advanced filtering (or both).

Specified by:

getXPathExpression in interface PredicateEvaluator

Overrides:

getXPathExpression in class DateRangePredicateEvaluator

Parameters:

p - predicate (for this evaluator type) which is evaluated

context - helper class which provides access to various elements of the query evaluation

Returns:

string containing an XPath predicateEvaluator expression

parseDateRange

public long parseDateRange(java.lang.String daterange)
                    throws java.lang.NumberFormatException

Throws:

java.lang.NumberFormatException
