protected Condition::mapConditionOperator($operator)
Gets any special processing requirements for the condition operator.
Some condition types require special processing, such as IN, because the value data they pass in is not a simple value. This is a simple overridable lookup function.
Parameters
$operator: The condition operator, such as "IN", "BETWEEN", etc. Case-sensitive.
Return value
array The extra handling directives for the specified operator or an empty array if there are no extra handling directives.
