Bio::Graphics::ConfiguratorI - A sectioned map of configuration options (a map of maps), with a default section. Intended to augment existing tag->value semantics (ie. of Bio::AnnotationCollectionI) for object-representation information (eg. foreground color), and for general interface preferences (eg. image width in gbrowse). # get a ConfiguratorI somehow my $fg_color = $configurator->get('fgcolor'); This object contains various configuration parameters. It is divided up into sections and tags. This is essentially a multi-level map (section->tag->value). There is also the concept of a default section which is referenced when no section is passed to the ConfiguratorI methods.

Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via email or the web: bioperl-bugs@bioperl.org http://bugzilla.bioperl.org/ Email rhubley@systemsbiology.org Paul Edlefsen, pedlefsen@systemsbiology.org Lincoln Stein, lstein@cshl.org Heikki Lehvaslaiho, heikki@ebi.ac.uk The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

get_sections
Title : get_sections Usage : my @values = $configurator->get_sections(); Function: Returns a list of the valid sections except the default or undef. Returns : A list of the sections which can be queried. Args : (optional section as string, tag as string)

get_tags
Title : get_tags Usage : my @values = $configurator->get_tags(); or my @values = $configurator->get_tags('dna'); Function: Returns a list of tags for a given section or only the default tags section if no section is given. Returns : A scalar list of tags Args :

get
Title : get Usage : my $value = $configurator->get('height'); or my $value = $configurator->get('dna','height'); Function: Returns a tag value from a configurator from the either the default "_general" section or from a specified section or undef. Returns : A scalar value for the tag Args : (optional section as string, tag as string)

set
Title : set Usage : $configurator->set('fgcolor','chartreuse'); or $configurator->set('EST','fgcolor','chartreuse'); Function: Set a value for a tag Returns : The old value of the tag Args : (optional section as string, tag as string, value as scalar)

get_and_eval
Title : get_and_eval Usage : my $value = $configurator->get_and_eval('height'); or my $value = $configurator->get_and_eval('dna','height'); Function: This works like get() except that it is also able to evaluate code references. These are options whose values begin with the characters "sub {". In this case the value will be passed to an eval() and the resulting codereference returned. Returns : A value of the tag or undef. Args : (optional section as string, tag as string)
