public class ParseFloatFieldUpdateProcessorFactory
- extends ParseNumericFieldUpdateProcessorFactory
Attempts to mutate selected fields that have only CharSequence-typed values
into Float values. If required, rounding uses ceiling mode:
RoundingMode.CEILING
. Grouping separators (',' in the ROOT locale)
are parsed.
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.FloatField, solr.TrieFloatField, or
solr.SortableFloatField.
If all values are parseable as float (or are already Float), then the field
will be mutated, replacing each value with its parsed Float 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
"12 345,899" as 12345.899f (the grouping separator character is U+00AO NO-BREAK
SPACE).

See Locale
for a description of acceptable language, country (optional)
and variant (optional) values, joined with underscore(s).
