Constructor Details

FilterAggregationBuilder

public FilterAggregationBuilder(String name,
 QueryBuilder filter)

Parameters:

name - the name of this aggregation

filter - Set the filter to use, only documents that match this filter will fall into the bucket defined by this Filter aggregation.

FilterAggregationBuilder

protected FilterAggregationBuilder(FilterAggregationBuilder clone,
 AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

FilterAggregationBuilder

public FilterAggregationBuilder(StreamInput in)
                         throws IOException

Read from a stream.

Throws:

IOException

Method Details

shallowCopy

protected AggregationBuilder shallowCopy(AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

Description copied from class: AggregationBuilder

Create a shallow copy of this builder and replacing AggregationBuilder.factoriesBuilder and metadata. Used by AggregationBuilder.rewrite(QueryRewriteContext).

Specified by:

shallowCopy in class AggregationBuilder

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class AbstractAggregationBuilder<FilterAggregationBuilder>

Throws:

IOException

bucketCardinality

public AggregationBuilder.BucketCardinality bucketCardinality()

Description copied from class: AggregationBuilder

A rough count of the number of buckets that Aggregators built by this builder will contain per owning parent bucket.

Specified by:

bucketCardinality in class AggregationBuilder

doRewrite

protected AggregationBuilder doRewrite(QueryRewriteContext queryRewriteContext)
                                throws IOException

Description copied from class: AggregationBuilder

Rewrites this aggregation builder into its primitive form. By default this method return the builder itself. If the builder did not change the identity reference must be returned otherwise the builder will be rewritten infinitely.

Overrides:

doRewrite in class AggregationBuilder

Throws:

IOException

doBuild

protected AggregatorFactory doBuild(AggregationContext context,

Specified by:

doBuild in class AbstractAggregationBuilder<FilterAggregationBuilder>

Throws:

IOException

internalXContent

protected XContentBuilder internalXContent(XContentBuilder builder,
 ToXContent.Params params)
                                    throws IOException

Specified by:

internalXContent in class AbstractAggregationBuilder<FilterAggregationBuilder>

Throws:

IOException

parse

public static FilterAggregationBuilder parse(XContentParser parser,
 String aggregationName)
                                      throws IOException

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractAggregationBuilder<FilterAggregationBuilder>

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractAggregationBuilder<FilterAggregationBuilder>

getType

Description copied from interface: BaseAggregationBuilder

The name of the type of aggregation built by this builder.

getFilter

public QueryBuilder getFilter()
