Classes which implement this interface may participate in the data binding process as formatted value converters.

import org.grails.databinding.converters.FormattedValueConverter

class FormattedStringValueConverter implements FormattedValueConverter {
    def convert(value, String format) {
        if('UPPERCASE' == format) {
            value = value.toUpperCase()
        } else if('LOWERCASE' == format) {
            value = value.toLowerCase()
        }
        value
    }

    Class getTargetType() {
        // specifies the type to which this converter may be applied
        String
    }
}
