RegexValidator

A validator for non-empty text made only of ASCII letters and digits, so spaces and punctuation are rejected. The pattern ends with $, which also accepts one trailing line break (abc followed by a line break passes). A mismatch reports Content must be alphanumeric.

Create a validator that searches for a pattern given as a string.

The pattern goes through org.llm4s.security.RegexSafetyManager.safeCompile. One that is refused or does not compile does not throw here: the validator is still returned, and every validate call fails with Invalid or unsafe regex pattern: <reason>.

Create a validator that searches for a scala.util.matching.Regex.

The pattern is used as given: unlike the String factories it is not pre-screened for dangerous shapes or length, though matching is still bounded.

Create a validator for a string pattern with a custom mismatch message.

As with the one-argument factory, a refused or invalid pattern fails every validate call with Invalid or unsafe regex pattern: <reason>; errorMessage is not used for that failure.

A validator for email addresses, using a basic pattern.

Accepts local@domain.tld with letters, digits and + _ . - in the local part. It is a format check, not proof that the address exists, and it does not implement the full email grammar. The pattern ends with $, which also accepts one trailing line break. A mismatch reports Invalid email address format.

A validator for phone numbers, using a basic pattern: an optional leading + and then 10 to 15 digits, with no spaces, dashes or brackets. The pattern ends with $, which also accepts one trailing line break. A mismatch reports Invalid phone number format.
