NotBlank

open class NotBlank @JvmOverloads constructor(val code: String = DEFAULT_CODE, val severity: ValidationIssueSeverity = ValidationIssueSeverity.Error) : Validation<CharSequence> (source)

Validation that checks that a string is not blank (according to String.isBlank) when it is also not empty.

When the string being validated is not empty and is blank, then an issue is emitted with the provided code (defaults to DEFAULT_CODE).

To forbid both empty and blank values, use this validation together with Required (preferred) or NotEmpty (if the value is nullable and null values should be accepted).

Parameters

code

Issue code to use when the string is not empty and blank.

severity

Severity of the issue emitted when the string is not empty and blank.
