java.lang.Object

com.yahoo.document.fieldpathupdate.FieldPathUpdate

public class RemoveFieldPathUpdate
extends FieldPathUpdate

RemoveFieldPathUpdate is used to remove fields or portions of fields based on the field path supplied and optionally a where clause. If document type "testdoc" has a field "ivec" which is an array of integers, then the field path and where clause to remove all array elements having the value 5 is "ivec[$x]" and "testdoc.ivec[$x] == 5". If document type "testdoc" has a field "svec" which is an array of struct containing an integer field "ival" then "svec[$x]" and "testdoc.svec[$x].ival == 5" can be used to remove all array elements where ival is 5.
