abstract public function DatabaseConnection::mapConditionOperator

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. Database connections should define only those operators they wish to be handled differently than the default.

Parameters

string $operator: The condition operator, such as "IN", "BETWEEN", etc. Case-sensitive.

Return value

array|null: The extra handling directives for the specified operator, or NULL.
