=head1 NAME

CQL::TermNode - represents a terminal Node in a CQL Parse Tree

=head1 SYNOPSIS

=head1 DESCRIPTION

CQL::TermNode represents a terminal in a CQL parse tree. A term node 
consists of the string itself with optional qualifier string and relation.
Examples could include:

=over 4

=item * george

=item * dc.creator=george

=back

=head1 METHODS

=head2 new()

The constructor which has must have at least a term attribute, and 
can also include optional qualifier and modifier terms.

=cut

sub new {
    my ($class,%args) = @_;
    croak( "must supply term parameter" ) if ! exists( $args{term} );
    return bless \%args, ref($class) || $class; 
}

=head2 getQualifier()

Get the qualifier in the terminal.

=cut

sub getQualifier {
    return shift->{qualifier};
}

=head2 getRelation()

Get the relation in the terminal.

=cut 

sub getRelation {
    return shift->{relation};
}

=head2 getTerm()

Get the actual term string in the terminal.

=cut

sub getTerm {
    return shift->{term};
}

=head2 toCQL()

Returns a CQL representation of the terminal node.
