Parameters:

type - The post aggregation type descriptor

name - The name of post aggregation

field - The list of field accessor post aggs

Method Detail

getField

public PostAggregation getField()

getPostAggregationType

public PostAggregationType getPostAggregationType()

getFields

public List<PostAggregation> getFields()

Description copied from interface: WithFields

An interface method to get all the post aggregation fields.

Specified by:

getFields in interface WithFields<FuzzySetPostAggregation>

Returns:

all the post aggregation fields when it is implemented

withName

public abstract FuzzySetPostAggregation withName(String name)

Description copied from class: PostAggregation

Get a new instance of this PostAggregation with the given name.

Specified by:

withName in class PostAggregation

Parameters:

name - Name of the new PostAggregation.

Returns:

a new instance of this with the given name

withField

public abstract FuzzySetPostAggregation withField(PostAggregation field)

Creates a new FuzzySetPostAggregation with the provided field.

Parameters:

field - Field for the new aggregation

Returns:

a new instance with the given field

withFields

public abstract FuzzySetPostAggregation withFields(List<PostAggregation> fields)

SketchEstimate converts the sketch into a number. Hence this method always should have one aggregator

Specified by:

withFields in interface WithFields<FuzzySetPostAggregation>

Parameters:

fields - List of post aggregation fields

Returns:

New SketchEstimatePostAggregation with provided field and only one aggregator.

equals

public boolean equals(Object o)

Overrides:

equals in class PostAggregation

hashCode

public int hashCode()

Overrides:

hashCode in class PostAggregation
