Package com.day.cq.search.eval

Class PermissionPredicateEvaluator

java.lang.Object

com.day.cq.search.eval.AbstractPredicateEvaluator

com.day.cq.search.eval.PermissionPredicateEvaluator

All Implemented Interfaces:

PredicateEvaluator

public class PermissionPredicateEvaluator
extends AbstractPredicateEvaluator

Restricts the result to items where the current session has the specified JCR privileges.

This is a filtering-only predicate and cannot leverage a search index. Does not support facet extraction.

Name:

hasPermission

Properties:

hasPermission

comma-separated JCR privileges that the current user session must ALL have for the node in question; for example jcr:write,jcr:modifyAccessControl

Since:

6.1

Method Detail

includes

public boolean includes(Predicate p,
                        javax.jcr.query.Row row,
                        EvaluationContext context)

Description copied from class: AbstractPredicateEvaluator

Default implementation that always returns true, ie. it does not "touch" the result set at all.

Specified by:

includes in interface PredicateEvaluator

Overrides:

includes in class AbstractPredicateEvaluator

Parameters:

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

row - current row of the result set returned through the xpath query

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

Returns:

true if this row should be part of the final result set, false if it should be dropped

canXpath

public boolean canXpath(Predicate predicate,
                        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 AbstractPredicateEvaluator

Parameters:

predicate - 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)

canFilter

public boolean canFilter(Predicate predicate,
                         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 AbstractPredicateEvaluator

Parameters:

predicate - 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)
