ScriptSortBuilder
Constructs a script sort builder with the given script.- Parameters:
script
- The script to use.type
- The type of the script, can be eitherScriptSortBuilder.ScriptSortType.STRING
orScriptSortBuilder.ScriptSortType.NUMBER
-
ScriptSortBuilder
Read from a stream.- Throws:
java.io.IOException

Method Details
-
writeTo
Description copied from interface:Writeable
Write this into the StreamOutput.- Throws:
java.io.IOException
-
script
Get the script used in this sort. -
type
Get the type used in this sort. -
sortMode
Defines which distance to use for sorting in the case a document contains multiple values.
ForScriptSortBuilder.ScriptSortType.STRING
, the set of possible values is restricted toSortMode.MIN
andSortMode.MAX
-
sortMode
Get the sort mode. -
setNestedFilter
Deprecated.set nested sort withsetNestedSort(NestedSortBuilder)
and retrieve withgetNestedSort()
Sets the nested filter that the nested objects should match with in order to be taken into account for sorting. -
getNestedFilter
Deprecated.set nested sort withsetNestedSort(NestedSortBuilder)
and retrieve withgetNestedSort()
Gets the nested filter. -
setNestedPath
Deprecated.set nested sort withsetNestedSort(NestedSortBuilder)
and retrieve withgetNestedSort()
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
@Deprecated public java.lang.String getNestedPath()Deprecated.set nested sort withsetNestedSort(NestedSortBuilder)
and retrieve withgetNestedSort()
Gets the nested path. -
getNestedSort
Returns theNestedSortBuilder
-
setNestedSort
Sets theNestedSortBuilder
to be used for fields that are inside a nested object. TheNestedSortBuilder
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 java.io.IOException- Throws:
java.io.IOException
-
fromXContent
- Parameters:
parser
- the input parser. The state on the parser contained in this context will be changed as a side effect of this method callelementName
- 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
-

-
getWriteableName
public java.lang.String getWriteableName()Description copied from interface:NamedWriteable
Returns the name of the writeable object -
rewrite
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:
java.io.IOException
