=head1 NAME
CQL::ModifierSet - represents a base string and modifier strings
=head1 SYNOPSIS
=head1 DESCRIPTION
This class is used as a delegate by both CQLRelation and
CQLProxNode - two functionally very separate classes that happen to
require similar data structures and functionality.
A ModifierSet consists of a ``base'' string together with a set of
zero or more type=value pairs, where both type and value are strings.
Types may be null, values may not.
=head1 METHODS
=head2 new()
Creates a new modifier set with the specified base.
=cut
sub new {
my ($class,$base) = @_;
my $self = { base => $base, modifiers => [] };
return bless $self, ref($class) || $class;
}
=head2 getBase()
Returns the base string with which the modifier set was created.
=cut
sub getBase {
return shift->{base};
}
=head2 addModifier()
Adds a modifier of the specified type and value to a modifier set.
=cut
sub addModifier {
my ($self,$type,$value) = @_;
push( @{ $self->{modifiers} }, [ $type => $value ] );
}
=head2 modifier()
Returns a modifier with a given type, or null if a modifier of that
type isn't present.
=cut
sub modifier {
my ($self,$type) = @_;
foreach my $pair ( @{ $self->{modifiers} } ) {
if ( $pair->[0] eq $type ) { return $pair->[1]; }
}
return undef;
}
=head2 getModifiers()
Returns a list of modifiers each represented by a 2 element array ref.
=cut
sub getModifiers {
my $self = shift;
return @{ $self->{modifiers} };
}
=head2 toCQL()
=cut
sub toCQL {
my $self = shift;
my $cql = $self->{base};
foreach ( @{ $self->{modifiers} } ) {
$cql .= "/" . $_->[1];
}
return $cql;
}
=head2 toSwish()
=cut
sub toSwish {
my $self = shift;
croak( "Swish does not support relational modifiers" )
if @{ $self->{modifiers} } > 0;
my $base = $self->getBase();
return $base if $base eq "=" or $base eq "not";
croak( "Swish doesn't support relations other than = and not" );
}
=head2 toXCQL()
=cut
sub toXCQL {
my ($self, $level, $topLevelElement) = @_;
my $buffer =
indent($level).'<'.$topLevelElement.">\n".
indent($level+1)."<value>".xq($self->{base})."</value>\n";
my @modifiers = $self->getModifiers();
if ( @modifiers > 0 ) {
$buffer .= indent($level+1)."<modifiers>\n";
foreach my $m ( @modifiers ) {
$buffer .= indent($level+2)."<modifier>";
$buffer .= "<type>".xq($m->[0])."</type>" if $m->[0];
$buffer .= "<value>".xq($m->[1])."</value></modifier>\n"
}
$buffer .= indent($level+1)."</modifiers>\n";
}
$buffer .= indent($level).'</'.$topLevelElement.">\n";
return $buffer;
