Kernel::System::SysConfig::ValueType::Textarea - System configuration text-area value type backed.

=head1 PUBLIC INTERFACE

=head2 new()

Create an object. Do not use it directly, instead use:

    use Kernel::System::ObjectManager;
    local $Kernel::OM = Kernel::System::ObjectManager->new();
    my $ValueTypeObject = $Kernel::OM->Get('Kernel::System::SysConfig::ValueType::Textarea');

    # Allocate new hash for object.
    my $Self = {};
    bless( $Self, $Type );

    return $Self;
}

=head2 SettingRender()

Extracts the effective value from a XML parsed setting.

    my $SettingHTML = $ValueTypeObject->SettingRender(
        Name           => 'SettingName',
        EffectiveValue => 'Textarea content', # (optional)
        DefaultValue   => 'Textarea content', # (optional)
        Class          => 'My class',         # (optional)
        Item           => [                   # (optional) XML parsed item
            {
                'ValueType' => 'Textarea',
                'Content' => 'Textarea content',
            },
        ],
        RW       => 1,                      # (optional) Allow editing. Default 0.
        IsArray  => 1,                      # (optional) Item is part of the array
        IsHash   => 1,                      # (optional) Item is part of the hash
        IDSuffix => 1,                      # (optional) Suffix will be added to the element ID
        SkipEffectiveValueCheck => 1,       # (optional) If enabled, system will not perform effective value check.
                                            #            Default: 1.
