The HTMLStripTransformer
You can use this transformer to strip HTML out of a field. For example:
...
There is one attribute for this transformer, stripHTML, which is a boolean value (true/false) to signal if the
HTMLStripTransformer should process the field or not.
The LogTransformer
You can use this transformer to log data to the console or log files. For example:
....
Unlike other transformers, the LogTransformer does not apply to any field, so the attributes are applied on the
entity itself.
The NumberFormatTransformer
Use this transformer to parse a number from a string, converting it into the specified format, and optionally using
a different locale.
NumberFormatTransformer will be applied only to fields with an attribute formatStyle.
This transformer recognizes the following attributes:
Attribute
formatStyle
sourceColName
locale
