NAME
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).
SYNOPSIS
# get a ConfiguratorI somehowmy $fg_color = $configurator->get('fgcolor');
DESCRIPTION
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.

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
get_sections
Title : get_sectionsUsage : my @values = $configurator->get_sections();Function: Returns a list of the valid sections exceptthe 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_tagsUsage : my @values = $configurator->get_tags();ormy @values = $configurator->get_tags('dna');Function: Returns a list of tags for a given sectionor only the default tags section if no sectionis given.Returns : A scalar list of tagsArgs :
get
Title : getUsage : my $value = $configurator->get('height');ormy $value = $configurator->get('dna','height');Function: Returns a tag value from a configurator from theeither the default "_general" section or froma specified section or undef.Returns : A scalar value for the tagArgs : (optional section as string, tag as string)
set
Title : setUsage : $configurator->set('fgcolor','chartreuse');or$configurator->set('EST','fgcolor','chartreuse');Function: Set a value for a tagReturns : The old value of the tagArgs : (optional section as string, tag as string, value as scalar)
get_and_eval
Title : get_and_evalUsage : my $value = $configurator->get_and_eval('height');ormy $value = $configurator->get_and_eval('dna','height');Function: This works like get() except that it isalso able to evaluate code references. These areoptions whose values begin with the characters"sub {". In this case the value will be passed toan eval() and the resulting codereference returned.Returns : A value of the tag or undef.Args : (optional section as string, tag as string)
