Class: String
Description
This method indicates whether the string satisfies a certain pattern. The pattern is specified as an SQL LIKE predicate. The current version of PSL supports the following likePatterns:
String.isLike("%substring%") which is equivalent to String["substring". (Note: PSL / M contains operator.)
String.isLike("substring%") which is equivalent to String.beginsWith("substring").
String.isLike("%substring") which is equivalent to String.endsWith("substring").
String.isLike("substring") which is equivalent to String="substring".

|
ignoreCase |

type Boolean NO = STR.isLike("be%") // case sensitive
set NO = STR.isLike("%flee%")
