.SH "NAME"
Bio::DB::GFF::Typename \-\- The name of a feature type
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use Bio::DB::GFF;
\&
\&  my $type = Bio::DB::GFF::Typename\->new(similarity => \*(AqBLAT_EST_GENOME\*(Aq);
\&  my $segment = $segment\->features($type);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Bio::DB::GFF::Typename objects encapsulate the combination of feature
method and source used by the \s-1GFF\s0 flat file format.  They can be used
in the Bio::DB::GFF modules wherever a feature type is called for.
.PP
Since there are relatively few types and many features, this module
maintains a memory cache of unique types so that two features of the
same type will share the same Bio::DB::GFF::Typename object.

\& Title   : new
\& Usage   : $type = Bio::DB::GFF::Typename\->new($method,$source)

\& Status  : Public
.Ve
.SS "source"
.IX Subsection "source"
.Vb 6
\& Title   : source
\& Usage   : $source = $type\->source([$newsource])

\& Status  : Public
.Ve
.SS "asString"
.IX Subsection "asString"
.Vb 6
\& Title   : asString
\& Usage   : $string = $type\->asString
\& Function: get the method and source as a string
\& Returns : a string in "method:source" format
\& Args    : none
\& Status  : Public
.Ve
.PP
This method is used by operator overloading to overload the '""'
operator.
.SS "clone"
.IX Subsection "clone"
.Vb 6
\& Title   : clone
\& Usage   : $new_clone = $type\->clone;
\& Function: clone this object
\& Returns : a new Bio::DB::GFF::Typename object
\& Args    : none
\& Status  : Public
.Ve
.PP
This method creates an exact copy of the object.
.SS "match"
.IX Subsection "match"
.Vb 6
\& Title   : match
\& Usage   : $boolean = $type\->match($type_or_string)
\& Function: fuzzy match on types
\& Returns : a flag indicating that the argument matches the object
\& Args    : a Bio::DB::GFF::typename object, or a string in method:source format
\& Status  : Public
.Ve
.PP
This match allows Sequence:Link and Sequence: to match, but not
Sequence:Link and Sequence:Genomic_canonical.
