NAME

Webservice::InterMine::Constraint::Binary - A representation of a binary attribute constraint

SYNOPSIS

my $constraint = $query->add_constraint("symbol", "=", "zen");

ok($constraint->isa("Webservice::InterMine::Constraint::Binary"));

DESCRIPTION

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 * (such as symbol = zen*). All equality operations are case insensitive, so symbol = zen and symbol = ZEN are identical.

  • !=

    The inverse of =.

  • <, <=, >, >=

    Numeric comparison. For strings, case sensitive alphanumeric sorting will be performed.

ATTIBUTES

value

the value this constraint constrains its attribute in relation to.
