public class ParseDoubleFieldUpdateProcessorFactory extends ParseNumericFieldUpdateProcessorFactory
Attempts to mutate selected fields that have only CharSequence-typed values
into Double values. If required, rounding uses ceiling mode:
RoundingMode.CEILING. Grouping separators (',' in the ROOT locale)
The default selection behavior is to mutate both those fields that don't match a schema field, as well as those fields that match a schema field with a field type that uses class solr.TrieDoubleField.
If all values are parseable as double (or are already Double), then the field will be mutated, replacing each value with its parsed Double equivalent; otherwise, no mutation will occur.
The locale to use when parsing field values, which will affect the recognized
grouping separator and decimal characters, may optionally be specified. If
no locale is configured, then
Locale.ROOT will be used. The following
configuration specifies the Russian/Russia locale, which will parse the string
string "12 345,899" as double value 12345.899 (the grouping separator
character is U+00AO NO-BREAK SPACE).
<processor class="solr.ParseDoubleFieldUpdateProcessorFactory"> <str name="locale">ru_RU</str> </processor>
Locale for a description of acceptable language, country (optional)
and variant (optional) values, joined with underscore(s).
