A Policy file in the installation directory of an LSST product, referred to using a URN.
For use of URN references in PAF-formatted policy files, see Policy Authoring Format.
The syntax is urn:eupspkg:[PRODUCT_NAME][:REPOSITORY]:PATH, although "urn:eupspkg:" may optionally be abbreviated with "@". PRODUCT_NAME is the name of an LSST product (see DefaultPolicyFile for more details on LSST product installation dirs), and REPOSITORY is a subdirectory, which other references within the Policy will be relative to (see Policy for more details on repositories).
For example:
Caveat: Only supports Dictionary's "DictionaryFile" directive if the value is prefixed like a normal URN reference with "@urn:eupspkg:" or "@@".

Construct a new policy file reference from a URN.
Basically, the only required element is a colon, separating the product directory from the local path.
urn | The URN of the policy file. A prefix such as "urn:eupspkg:" or "@" is optional. |
strictUrn | if true, the URN must strictly begin with "@urn:eupspkg:" or "urn:eupspkg:". |
strictLoads | if true (default), load() will throw an exception if it encounters recoverable parsing errors in the underlying file (or any of the files it references). Otherwise, the loaded Policy will be incomplete. This is identical to the strict argument to Policy's loadPolicyFiles(). |

return true if the file exists.

static |
Extract the local file path from a URN.
For example,
|
virtualinherited |
return the name of the format that the data is stored in.
This may cause the first few records of the source to be read. In this implementation, once the format is definitely determined, the format name is cached internally, preventing re-determination on the next call to this function.
IOError | if an error occurs while reading the first few characters of the source stream. |

This implementation uses the implementation provided by DefaultPolicyFile::installPathFor().

return the file path to the installation directory of a given named product.
In this implementation, the installation directory will be taken from the value of an environment variable PRODUCTNAME_DIR where PRODUCTNAME is the given name of the product with all letters converted to upper case.

load the data from this Policy source into a Policy object.
This implementation will automatically de-reference any file include directives in the policy file.
