When to call the "call" function in class "TemporalPatternAttentionCellWrapper"?

[Tiffanyxq]

Hi! I find the usage of "call" function should be like "cell.call(inputs, state)", but in the "TemporalPatternAttentionCellWrapper" class, the "call" function is not used, I don't understand the code well. Could anyone teach me about this? Thanks a lot!
