class Operator[source]#

Bases: OperatorBase

The operator definition in a planning domain.

Methods

`pddl_str`()	Return the PDDL representation of the operator.
`rename`(new_name[, is_primitive])	Rename the operator.

Attributes

`argument_names`	The names of the arguments of the operator.
`argument_types`	The types of the arguments of the operator.
`is_axiom`	Whether this operator is an axiom.
`is_macro`	Whether the operator is a macro operator.
`is_primitive`	Whether this operator is a primitive operator (instead of a macro operator or a sub operator in a macro).
`nr_arguments`	The number of arguments of the operator.
`name`	The name of the operator.
`arguments`	The list of arguments of the operator.
`preconditions`	The list of preconditions of the operator.
`effects`	The list of effects of the operator.
`controller`	The controller function of the operator.
`is_template`	Whether this operator is a template.
`extends`	The name of the operator that this operator extends.

__call__(*args)[source]#

Ground the operator with a list of arguments.
