Webservice::InterMine::Constraint::Binary - A representation of a binary attribute constraint
my $constraint = $query->add_constraint("symbol", "=", "zen"); ok($constraint->isa("Webservice::InterMine::Constraint::Binary"));
Constraints are constructed by queries based on the arguments to
add_constraint, or a similar method (such as
where). Binary constraints constrain the values of attributes, and can have one of the following operators:
Equality. Allows wildcards with
symbol = zen*). All equality operations are case insensitive, so
symbol = zenand
symbol = ZENare identical.
The inverse of
Numeric comparison. For strings, case sensitive alphanumeric sorting will be performed.
the value this constraint constrains its attribute in relation to.
