This one is used for bi-directional signals. You have enable signal to choose direction as well as input and output signal to your internal logic. The bi-directional signal goes to outside pin.

If it's low, the primitive works as input buffer to fpga. It it's high, the primitive is output buffer.

The signal polarity is obvious from the definition. All control signals have positive polarity unless explicitely inverted. A signal "oe" does what it's name tells.
