Class SubstringReplacer

All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable, EventListener, Accessible, EnvironmentHandler, BeanCommon, DataSource, EventConstraints, InstanceListener, Visible

@KFStep(category="Tools", toolTipText="Replace substrings in String attributes") public class SubstringReplacer extends JPanel implements BeanCommon, Visible, Serializable, InstanceListener, EventConstraints, EnvironmentHandler, DataSource
A bean that can replace substrings in the values of string attributes. Multiple match and replace "rules" can be specified - these get applied in the order that they are defined. Each rule can be applied to one or more user-specified input String attributes. Attributes can be specified using either a range list (e.g 1,2-10,last) or by a comma separated list of attribute names (where "/first" and "/last" are special strings indicating the first and last attribute respectively). Matching can be by string literal or by regular expression.
