Examples of cascading.operation.regex.RegexFilter

cascading.operation.regex.RegexFilter
Class RegexFilter will apply the regex patternString against every input Tuple value and filter the Tuple stream accordingly.
By default, Tuples that match the given pattern are kept, and Tuples that do not match are filtered out. This can be changed by setting removeMatch to true.
Also, by default, the whole Tuple is matched against the given patternString (tab delimited). If matchEachElement is set to true, the pattern is applied to each Tuple value individually.
This operation uses {@link java.util.regex.Matcher} internally, specifically the method {@link java.util.regex.Matcher#find()}. @see java.util.regex.Matcher @see java.util.regex.Pattern
