Modifier and Type	Method and Description
protected ValuesSourceAggregationBuilder<ValuesSource,ValueCountAggregationBuilder>	createFactory(java.lang.String aggregationName, ValuesSourceType valuesSourceType, ValueType targetValueType, java.util.Map<ParseField,java.lang.Object> otherOptions) Creates a ValuesSourceAggregationBuilder from the information gathered by the subclass.

                 throws java.io.IOException

Description copied from class: AbstractValuesSourceParser

Allows subclasses of AbstractValuesSourceParser to parse extra parameters and store them in a Map which will later be passed to AbstractValuesSourceParser.createFactory(String, ValuesSourceType, ValueType, Map).

Specified by:

token in class AbstractValuesSourceParser<ValuesSource>

Parameters:

aggregationName - the name of the aggregation

currentFieldName - the name of the current field being parsed

token - the current token for the parser

context - the query context

otherOptions - a Map of options to be populated by successive calls to this method which will then be passed to the AbstractValuesSourceParser.createFactory(String, ValuesSourceType, ValueType, Map) method

Returns:

true if the current token was correctly parsed, false otherwise

Throws:

java.io.IOException - if an error occurs whilst parsing

createFactory

protected ValuesSourceAggregationBuilder<ValuesSource,ValueCountAggregationBuilder> createFactory(java.lang.String aggregationName,
                                                                                                  ValuesSourceType valuesSourceType,
                                                                                                  ValueType targetValueType,
                                                                                                  java.util.Map<ParseField,java.lang.Object> otherOptions)

Description copied from class: AbstractValuesSourceParser

Creates a ValuesSourceAggregationBuilder from the information gathered by the subclass. Options parsed in AbstractValuesSourceParser itself will be added to the factory after it has been returned by this method.

Specified by:

createFactory in class AbstractValuesSourceParser<ValuesSource>

Parameters:

aggregationName - the name of the aggregation

valuesSourceType - the type of the ValuesSource

targetValueType - the target type of the final value output by the aggregation

otherOptions - a Map containing the extra options parsed by the AbstractValuesSourceParser.token(String, String, XContentParser.Token, XContentParseContext, Map) method

Returns:

the created factory
