# current_op/3

## Description

    current_op(Priority, Specifier, Operator)

Enumerates, by backtracking, the visible operators declared for an object. Operators not declared using a scope directive are not enumerated.

## Modes and number of proofs

    current_op(?operator_priority, ?operator_specifier, ?atom) - zero_or_more

## Errors

Priority is neither a variable nor an integer:
`type_error(integer, Priority)`
Priority is an integer but not a valid operator priority:
`domain_error(operator_priority, Priority)`
Specifier is neither a variable nor an atom:
`type_error(atom, Specifier)`
Specifier is an atom but not a valid operator specifier:
`domain_error(operator_specifier, Specifier)`
Operator is neither a variable nor an atom:
`type_error(atom, Operator)`

## Examples

To enumerate, by backtracking, the local operators or the operators visible in this:
`current_op(Priority, Specifier, Operator)`
To enumerate, by backtracking, the public and protected operators visible in self:
`::current_op(Priority, Specifier, Operator)`
To enumerate, by backtracking, the public operators visible for an explicit object:
`Object::current_op(Priority, Specifier, Operator)`
