Class ChangeQueryProcessor

java.lang.Object

com.google.gerrit.index.query.QueryProcessor<ChangeData>

com.google.gerrit.server.query.change.ChangeQueryProcessor

All Implemented Interfaces:

DynamicOptions.BeanProvider, DynamicOptions.BeanReceiver

public class ChangeQueryProcessor
extends QueryProcessor<ChangeData>
implements DynamicOptions.BeanReceiver, DynamicOptions.BeanProvider

Query processor for the change index.

Instances are one-time-use. Other singleton classes should inject a Provider rather than holding on to a single instance.

Method Detail

enforceVisibility

public ChangeQueryProcessor enforceVisibility(boolean enforce)

Description copied from class: QueryProcessor

Specify whether to enforce visibility by filtering out results that are not visible to the user.

Enforcing visibility may have performance consequences, as the index system may need to post-filter a large number of results to fill even a modest limit.

If visibility is enforced, the user's queryLimit global capability is also used to bound the total number of results. If this capability is non-positive, this results in the entire query processor being disabled.

Overrides:

enforceVisibility in class QueryProcessor<ChangeData>

Parameters:

enforce - whether to enforce visibility.

Returns:

this.

createOptions

protected QueryOptions createOptions(IndexConfig indexConfig,
                                     int start,
                                     int limit,
                                     java.util.Set<java.lang.String> requestedFields)

Overrides:

createOptions in class QueryProcessor<ChangeData>

setDynamicBean

public void setDynamicBean(java.lang.String plugin,
                           DynamicOptions.DynamicBean dynamicBean)

Specified by:

setDynamicBean in interface DynamicOptions.BeanReceiver

getDynamicBean

public DynamicOptions.DynamicBean getDynamicBean(java.lang.String plugin)

Specified by:

getDynamicBean in interface DynamicOptions.BeanProvider

getAttributesFactory

public PluginDefinedAttributesFactory getAttributesFactory()

enforceVisibility

protected Predicate<ChangeData> enforceVisibility(Predicate<ChangeData> pred)

Description copied from class: QueryProcessor

Invoked after the query was rewritten. Subclasses must overwrite this method to filter out results that are not visible to the calling user.

Specified by:

enforceVisibility in class QueryProcessor<ChangeData>

Parameters:

pred - the query

Returns:

the modified query

formatForLogging

protected java.lang.String formatForLogging(ChangeData changeData)

Specified by:

formatForLogging in class QueryProcessor<ChangeData>
