Constructor Details

ScriptSortBuilder

public ScriptSortBuilder(Script script,
 ScriptSortBuilder.ScriptSortType type)

Constructs a script sort builder with the given script.

Parameters:

script - The script to use.

type - The type of the script, can be ScriptSortBuilder.ScriptSortType.STRING, ScriptSortBuilder.ScriptSortType.NUMBER or ScriptSortBuilder.ScriptSortType.VERSION

ScriptSortBuilder

public ScriptSortBuilder(StreamInput in)
                  throws IOException

Read from a stream.

Throws:

IOException

Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Throws:

IOException

script

public Script script()

Get the script used in this sort.

type

public ScriptSortBuilder.ScriptSortType type()

Get the type used in this sort.

sortMode

public ScriptSortBuilder sortMode(SortMode sortMode)

Defines which distance to use for sorting in the case a document contains multiple values.
For ScriptSortBuilder.ScriptSortType.STRING, the set of possible values is restricted to SortMode.MIN and SortMode.MAX

sortMode

public SortMode sortMode()

Get the sort mode.

getNestedSort

public NestedSortBuilder getNestedSort()

Returns the NestedSortBuilder

setNestedSort

public ScriptSortBuilder setNestedSort(NestedSortBuilder nestedSort)

Sets the NestedSortBuilder to be used for fields that are inside a nested object. The NestedSortBuilder takes a `path` argument and an optional nested filter that the nested objects should match with in order to be taken into account for sorting.

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
 ToXContent.Params builderParams)
                           throws IOException

Throws:

IOException

fromXContent

public static ScriptSortBuilder fromXContent(XContentParser parser,
 String elementName)

Creates a new ScriptSortBuilder from the query held by the XContentParser in XContent format.

Parameters:

parser - the input parser. The state on the parser contained in this context will be changed as a side effect of this method call

elementName - in some sort syntax variations the field name precedes the xContent object that specifies further parameters, e.g. in '{ "foo": { "order" : "asc"} }'. When parsing the inner object, the field name can be passed in via this argument

build

public SortFieldAndFormat build(SearchExecutionContext context)
                         throws IOException

Description copied from class: SortBuilder

Create a SortFieldAndFormat from this builder.

Specified by:

build in class SortBuilder<ScriptSortBuilder>

Throws:

IOException

buildBucketedSort

public BucketedSort buildBucketedSort(SearchExecutionContext context,
 BigArrays bigArrays,
 int bucketSize,
 BucketedSort.ExtraData extra)
                               throws IOException

Description copied from class: SortBuilder

Create a BucketedSort which is useful for sorting inside of aggregations.

Specified by:

buildBucketedSort in class SortBuilder<ScriptSortBuilder>

Throws:

IOException

equals

public boolean equals(Object object)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

getWriteableName

public String getWriteableName()

Description copied from interface: VersionedNamedWriteable

Returns the name of the writeable object

getMinimalSupportedVersion

public Version getMinimalSupportedVersion()

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to

rewrite

public ScriptSortBuilder rewrite(QueryRewriteContext ctx)
                          throws IOException

Description copied from interface: Rewriteable

Rewrites this instance based on the provided context. The returned objects will be the same instance as this if no changes during the rewrite were applied.

Throws:

IOException
