Enum BucketHelpers.GapPolicy

java.lang.Object

java.lang.Enum<BucketHelpers.GapPolicy>

org.elasticsearch.search.aggregations.pipeline.BucketHelpers.GapPolicy

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<BucketHelpers.GapPolicy>

Enclosing class:

BucketHelpers

public static enum BucketHelpers.GapPolicy
extends java.lang.Enum<BucketHelpers.GapPolicy>

A gap policy determines how "holes" in a set of buckets should be handled. For example, a date_histogram might have empty buckets due to no data existing for that time interval. This can cause problems for operations like a derivative, which relies on a continuous function. "insert_zeros": empty buckets will be filled with zeros for all metrics "ignore": empty buckets will simply be ignored

Method Detail

values

public static BucketHelpers.GapPolicy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (BucketHelpers.GapPolicy c : BucketHelpers.GapPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static BucketHelpers.GapPolicy valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

parse

public static BucketHelpers.GapPolicy parse(QueryParseContext context,
                                            java.lang.String text,
                                            XContentLocation tokenLocation)

Parse a string GapPolicy into the byte enum

Parameters:

context - SearchContext this is taking place in

text - GapPolicy in string format (e.g. "ignore")

Returns:

GapPolicy enum

writeTo

public void writeTo(StreamOutput out)
             throws java.io.IOException

Serialize the GapPolicy to the output stream

Throws:

java.io.IOException

readFrom

public static BucketHelpers.GapPolicy readFrom(StreamInput in)
                                        throws java.io.IOException

Deserialize the GapPolicy from the input stream

Returns:

GapPolicy Enum

Throws:

java.io.IOException

getName

public java.lang.String getName()

Return the english-formatted name of the GapPolicy

Returns:

English representation of GapPolicy
