Class DateFormatTransformer

java.lang.Object
com.norconex.importer.handler.transformer.impl.DateFormatTransformer
All Implemented Interfaces:
Configurable<DateFormatTransformerConfig>, ConfigurableDocHandler<DateFormatTransformerConfig>, DocHandler
public class DateFormatTransformer extends Object implements ConfigurableDocHandler<DateFormatTransformerConfig>

Formats a date from any given format to a format of choice, as per the formatting options found on ZonedDateTimeParser with the addition of the format "EPOCH", which represents the difference, measured in milliseconds, between the date and midnight, January 1, 1970. The default format for fromFormat or toFormat when not specified is EPOCH.

When omitting the toField, the value will replace the one in the same field.

Storing values in an existing field

If a target field with the same name already exists for a document, values will be added to the end of the existing value list. It is possible to change this default behavior with DateFormatTransformerConfig.setOnSet(PropertySetter).

Can be used both as a pre-parse or post-parse handler.

It is possible to specify a locale used for parsing and formatting dates. The locale is the ISO two-letter language code, with an optional ISO country code, separated with an underscore (e.g., "fr" for French, "fr_CA" for Canadian French). When no locale is specified, the default is English.

Multiple fromFormat values can be specified. Each formats will be tried in the order provided and the first format that succeed in parsing a date will be used. A date will be considered "bad" only if none of the formats could parse the date.

The following converts a date that is sometimes obtained from the HTTP header "Last-Modified" and sometimes is an EPOCH date, into an Apache Solr date format:
