=head1 NAME

Bio::SearchIO::EventHandlerI - An abstract Event Handler for Search Result parsing

=head1 SYNOPSIS

# do not use this object directly it is an interface
# See Bio::SearchIO::SearchResultEventBuilder for an implementation

    use Bio::SearchIO::SearchResultEventBuilder;
    my $handler = new Bio::SearchIO::SearchResultEventBuilder();

=head1 DESCRIPTION

This interface describes the basic methods needed to handle Events
thrown from parsing a Search Result such as FASTA, BLAST, or HMMer.
