Class DateRangePredicateEvaluator

All Implemented Interfaces:

Direct Known Subclasses:

RelativeDateRangePredicateEvaluator

public class DateRangePredicateEvaluator
extends RangePropertyPredicateEvaluator

DateRangePropertyPredicate is a generic evaluator for checking a jcr DATE property against an interval. This uses the ISO8601 format for dates (YYYY-MM-DDTHH:mm:ss.SSSZ) and allows also partial representations (eg. YYYY-MM-DD). You can also provide the dates (for the bounds) as number of milliseconds since 1970 (UTC timezone, basically the unix format).

You can define a lower bound and an upper bound or only one of them. The operation (eg. "lesser than" or "lesser or equals") can also be specified for lower and upper bound individually.

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

Name:

daterange

Properties:

property

relative path to a DATE property

lowerBound

lower bound to check property for

lowerOperation

">" (default) or ">=", applies to the lowerBound

upperBound

upper bound to check property for

upperOperation

"<" (default) or "<=", applies to the upperBound

timeZone

ID of timezone to use when it's not given in the ISO-8601 date string; default is the default timezone of the system

Since:

5.2

Method Detail

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 RangePropertyPredicateEvaluator

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

canFilter

public boolean canFilter(Predicate p,
                         EvaluationContext context)

Description copied from class: AbstractPredicateEvaluator

Returns the same as the deprecated AbstractPredicateEvaluator.isFiltering(Predicate, EvaluationContext) method (ie. if not overridden, false).

Specified by:

canFilter in interface PredicateEvaluator

Overrides:

canFilter in class RangePropertyPredicateEvaluator

Parameters:

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

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

Returns:

true if this evaluator can be express itself via filtering, ie. PredicateEvaluator.includes(Predicate, Row, EvaluationContext)

canXpath

public boolean canXpath(Predicate p,
                        EvaluationContext context)

Description copied from class: AbstractPredicateEvaluator

Returns the inverted boolean value of the deprecated AbstractPredicateEvaluator.isFiltering(Predicate, EvaluationContext) method (ie. if not overridden, true).

Specified by:

canXpath in interface PredicateEvaluator

Overrides:

canXpath in class RangePropertyPredicateEvaluator

Parameters:

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

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

Returns:

true if this evaluator can express itself via xpath, ie. PredicateEvaluator.getXPathExpression(Predicate, EvaluationContext)

parseDateString

public static java.lang.String parseDateString(java.lang.String dateString,
                                               java.lang.String timeZoneID,
                                               Session session)

getFacetExtractor

public FacetExtractor getFacetExtractor(Predicate p,
                                        EvaluationContext context)

Description copied from class: AbstractPredicateEvaluator

Default implementation that always returns null, ie. no facets will be extracted for the predicate.

Specified by:

getFacetExtractor in interface PredicateEvaluator

Overrides:

getFacetExtractor in class AbstractPredicateEvaluator

Parameters:

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

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

Returns:

a FacetExtractor that is used to create a Facet or null if no extractor shall be provided
