NAME

Validate - Validation components for the TVision framework

SYNOPSIS

use TUI::Validate;

# Typical validator setup flow:
my $filter = TFilterValidator->new( validChars => '[0-9]' );
my $range  = TRangeValidator->new( min => 1, max => 9999 );

my $ok1 = $filter->isValid('1234');
my $ok2 = $range->isValid('42');

DESCRIPTION

TUI::Validate provides the validator layer for the TVision framework. It corresponds to the Turbo Vision validation subsystem and collects the validator base classes, concrete validators, and related constants.

Importing this module re-exports the full validator surface, including:

• Const Symbolic constants for validator status, options, and transfer flags.

• Base and generic validator classes - TValidator, TFilterValidator, TLookupValidator.

• Lookup-based validator - TStringLookupValidator.

• Numeric range validator - TRangeValidator.

• Picture-mask validator - TPXPictureValidator.

Calling no TUI::Validate; forwards to the corresponding unimport implementations of these modules.
