DCSwitch.get_case()¶: Returns the DCPackerInterface that packs the nth case.

DCSwitch.get_case_by_value()¶: Returns the index number of the case with the indicated packed value, or -1 if no case has this value.

DCSwitch.get_default_case()¶: Returns the DCPackerInterface that packs the default case, or NULL if there is no default case.

DCSwitch.get_field()¶: Returns the nth field in the indicated case.

DCSwitch.get_field_by_name()¶: Returns the field with the given name from the indicated case, or NULL if no field has this name.

DCSwitch.get_key_parameter()¶: Returns the key parameter on which the switch is based. The value of this parameter in the record determines which one of the several cases within the switch will be used.
