Examples of cascading.operation.assertion.AssertMatches

cascading.operation.assertion.AssertMatches
Class AssertMatches matches the given regular expression patternString against the whole argument {@link cascading.tuple.Tuple} by joining each individual element of the Tuple with a tab character (\t).See {@link AssertMatchesAll} if you need to match the patternString regex against each individual tuple element.
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
