The Resource data type

There is also a general Resource data type, which all <SOME ARBITRARY RESOURCE TYPE> data types are more-specific subtypes of. Like the Mytype-style data types, it matches no values that can be produced in the Puppet language. You can use parameters to restrict which values Resource matches, but it still matches no values.

This is useful in the following uncommon circumstances:

You need to interact with a resource type before you know its name. For example, you can do some clever business with the iteration functions to re-implement the create_resources function in the Puppet language, where your lambda receives arguments telling it to create resources of some resource type at runtime.
Someone has somehow created a resource type whose name is invalid in the Puppet language, possibly by conflicting with a reserved word — you can use a Resource value to refer to that resource type in resource declarations and resource default statements, and to create resource references.

Parameters

The full signature for Resource is:

Resource[<RESOURCE TYPE>, <RESOURCE TITLE>...]

All of these parameters are optional. They must be listed in order; if you need to specify a later parameter, you must specify values for any prior ones.

Position	Parameter	Data type	Default value	Description
1	Resource type	`String` or `Resource`	nothing	A resource type, either as a string or a `Resource` data type value. If provided, this turns this data type into a resource-specific data type. `Resource[Mytype]` and `Resource["mytype"]` are identical to the data type `Mytype`.
2 and higher	Resource title	`String`	nothing	The title of some specific resource of this type. If provided, this turns this data type into a usable resource reference or array of resource references. `Resource[Mytype, "mytitle"]` and `Resource["mytype", "mytitle"]` are identical to the data type `Mytype["mytitle"]`.

Examples:

Resource[File]

The data type corresponding to the file resource type.

Resource[File, '/tmp/filename.ext']

A resource reference to the file resource whose title is /tmp/filename.ext.

Resource["file",
                            '/tmp/filename.ext']

A resource reference to the file resource whose title is /tmp/filename.ext.

Resource[File, '/tmp/filename.ext',
                                '/tmp/bar']

Equivalent to

[ File['/tmp/filename.ext'],
                                File['/tmp/bar'] ]

Type[Resource[File]]

A synonym for the data type that matches any resource references to file resources. This is useful for, for example, restricting the values of class or defined type parameters.

Type[Resource["file"]]

Another synonym for the data type that matches any resource references to file resources. This is useful for, for example, restricting the values of class or defined type parameters.
