Use the following code to recursively print the contents of an exacct object. Note that this capability is provided by the library as the Sun::Solaris::Exacct::Object::dump() function. This capability is also available through the ea_dump_object() convenience function.
sub dump_object { my ($obj, $indent) = @_; my $istr = ' ' x $indent; # # Retrieve the catalog tag. Because we are # doing this in an array context, the # catalog tag will be returned as a (type, catalog, id) # triplet, where each member of the triplet will behave as # an integer or a string, depending on context. # If instead this next line provided a scalar context, e.g. # my $cat = $obj->catalog()->value(); # then $cat would be set to the integer value of the # catalog tag. # my @cat = $obj->catalog()->value(); # # If the object is a plain item # if ($obj->type() == &EO_ITEM) { # # Note: The '%s' formats provide s string context, so # the components of the catalog tag will be displayed # as the symbolic values. If we changed the '%s' # formats to '%d', the numeric value of the components # would be displayed. # printf("%sITEM\n%s Catalog = %s|%s|%s\n", $istr, $istr, @cat); $indent++; # # Retrieve the value of the item. If the item contains # in turn a nested exacct object (i.e., an item or # group),then the value method will return a reference # to the appropriate sort of perl object # (Exacct::Object::Item or Exacct::Object::Group). # We could of course figure out that the item contained # a nested item orgroup by examining the catalog tag in # @cat and looking for a type of EXT_EXACCT_OBJECT or # EXT_GROUP. # my $val = $obj->value(); if (ref($val)) { # If it is a nested object, recurse to dump it. dump_object($val, $indent); } else { # Otherwise it is just a 'plain' value, so # display it. printf("%s Value = %s\n", $istr, $val); } # # Otherwise we know we are dealing with a group. Groups # represent contents as a perl list or array (depending on # context), so we can process the contents of the group # with a 'foreach' loop, which provides a list context. # In a list context the value method returns the content # of the group as a perl list, which is the quickest # mechanism, but doesn't allow the group to be modified. # If we wanted to modify the contents of the group we could # do so like this: # my $grp = $obj->value(); # Returns an array reference # $grp->[0] = $newitem; # but accessing the group elements this way is much slower. # } else { printf("%sGROUP\n%s Catalog = %s|%s|%s\n", $istr, $istr, @cat); $indent++; # 'foreach' provides a list context. foreach my $val ($obj->value()) { dump_object($val, $indent); } printf("%sENDGROUP\n", $istr); } } |
