use Net::DNS::SEC::Tools::TrustAnchor;

$tar = new Net::DNS::SEC::Tools::TrustAnchor();

Initializes a new collection of trust anchors.

$module = load_module("type");

Dynamically attemps to load a TrustAnchor reader/writer sub-class of Net::DNS::SEC::Tools::TrustAnchor named "Type" and return an instance of it.

All sub-classes are assumed to contain a single letter upper-case class name followed by all lower case. Any modules otherwise named will fail to load using this routine.

$module = parse_component("type:file");

This parses a type and file specification consisting of type separated by a colon (':') followed by a file-name path. It will then load the type module using the load_module() rotine and return the type, the file and extra options.

XXX: option parsing support not yet complete and will likely change the type:file format specification; I.E. the type:file formatting specification will likely change in the future and should be considered alpha-level support.

$tar = $module->read($location, $options);

Reads in a given TAR from a $location reference and returns a blessed copy of the Net::DNS::SEC::Tools::TrustAnchor object containing all the data.

This function may be over-ridden by a sub-class.

$tar = $module->read($location, $options);

Reads in a given TAR from a $location reference and returns an unblessed hash the contents. The read() function merely wraps around this and blesses it after being returned.

Sub-modules must over-ride this function (and/or the read() function) if they expect the module to support loading.

$tar->merge(@others)

Merges the @other array of trust anchors into the $tar object's own trust anchor list.
