All Implemented Interfaces:

SQLMethod

public class StringMatchesDerbyMethod
extends StringMatchesMethod

Expression handler to evaluate {stringExpression}.matches(StringExpression) for Derby. Adds its own handling of the case of "{StringExpression} LIKE {StringExpression}" case using a Java function NUCLEUS_MATCHES in the datastore since Derby doesn't support "LIKE". Note that any input escape character is ignored.
