Constructor Detail

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 either ScriptSortBuilder.ScriptSortType.STRING or ScriptSortBuilder.ScriptSortType.NUMBER

ScriptSortBuilder

public ScriptSortBuilder(StreamInput in)
                  throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

Method Detail

writeTo

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

Description copied from interface: Writeable

Write this into the StreamOutput.

Throws:

java.io.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.

setNestedFilter

public ScriptSortBuilder setNestedFilter(QueryBuilder nestedFilter)

Sets the nested filter that the nested objects should match with in order to be taken into account for sorting.

getNestedFilter

public QueryBuilder getNestedFilter()

Gets the nested filter.

setNestedPath

public ScriptSortBuilder setNestedPath(java.lang.String nestedPath)

Sets the nested path if sorting occurs on a field that is inside a nested object. For sorting by script this needs to be specified.

getNestedPath

public java.lang.String getNestedPath()

Gets the nested path.

toXContent

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

Throws:

java.io.IOException

fromXContent

public static ScriptSortBuilder fromXContent(QueryParseContext context,
                                             java.lang.String elementName)
                                      throws java.io.IOException

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

Parameters:

context - the input parse context. 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

Throws:

java.io.IOException
