Bio::Graphics::ConfiguUserrContributed Perl DocBio::Graphics::ConfiguratorI(3)NAMEBio::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 somehow
my $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_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)
