NAME
GO::Utils - utilities for GO modules rearrange() Usage : n/a Function : Rearranges named parameters to requested order. Returns : @params - an array of parameters in the requested order. Argument : $order : a reference to an array which describes the desired order of the named parameters. @param : an array of parameters, either as a list (in which case the function simply returns the list), or as an associative array (in which case the function sorts the values according to @{$order} and returns that new array. Exceptions : carps if a non-recognised parameter is sent get_param() Usage : get_param('name',(-att1=>'ben',-name=>'the_name')) Function : Fetches a named parameter. Returns : The value of the requested parameter. Argument : $name : The name of the the parameter desired @param : an array of parameters, as an associative array Exceptions : carps if a non-recognised parameter is sent Based on rearrange(), which is originally from CGI.pm by Lincoln Stein and BioPerl by Richard Resnick. See rearrange() for details. remove_duplicates remove duplicate items from an array usage: remove_duplicates(@arr) affects the array passed in, and returns the modified array merge_hashes joins two hashes together usage: merge_hashes(\%h1, \%h2); %h1 will now contain the key/val pairs of %h2 as well. if there are key conflicts, %h2 values will take precedence. get_method_ref returns a pointer to a particular objects method e.g. my $length_f = get_method_ref($seq, 'length'); $len = &$length_f(); pset2hash Usage - my $h = pset2hash([{name=>"id", value=>"56"}, {name=>"name", value=>"jim"}]); Returns - hashref Args - arrayref of name/value keyed hashrefs spell_greek takes a word as a parameter and spells out any greek symbols encoded within (eg s/&agr;/alpha/g) check_obj_graph Usage - Returns - true if cycle detected Args - any object perl v5.14.2 2013-02-07 GO::Utils(3pm)
