Purpose: Matches string messages against a regular expression.
Minimum Configuration: The pattern string for the match.
Discussion: The RegEx Filter applies a regular expression pattern, such as a pattern that includes wildcards or other character substitution symbols, to the message payload. The filter applies the
toString() method to the payload to convert the payload to a String. To ensure that the payload is a String, you might want to apply a Payload Filter to the message with a nested And Logic Filter.
