# Params::Validate::Dummy(3pm)

Stub for Params::Validate

## NAME

Params::Validate::Dummy - Stub for Params::Validate

## SYNOPSIS

```
  use Params::Validate::Dummy qw();
  use Module::Optional qw(Params::Validate);
```

## DESCRIPTION

This module provides stub routines for those who don't have Params::Validate installed.

For more details, please refer to the documentation for Params::Validate.

The code here is just stub routines which do NOTHING at all, passing through any arguments in the API and prototypes of Params::Validate. In  particular, the dummy stubs do not do defaulting, validation, untainting or anything else that Params::Validate does. If you need this functionality, either provide it yourself in the surrounding code, or don't use this module and insist that the real Params::Validate is installed.

### "validate", "validate\_pos"

The parameter list is passed through as a return value.

### "validate\_with"

Returns the value of the params option.

### "set\_options", "validation\_options"

These do nothing at all.

### Data types: "SCALAR", "SCALARREF", "ARRAYREF", "HASHREF", "GLOB", "GLOBREF", "BOOLEAN", "CODEREF", "HANDLE", "OBJECT", "UNDEF", "UNKNOWN"

In the Params::Validate module, these are constants implemented by subs that return numbers. This module implements the same functions.
