trying to understand how gob(golang) work

[WALID BELRHALMIA]

in my ambitions to understand how gob work . i have severals question .

i know that gob serialize a go type like struct map or interface(we must register it's real type) but :

func (dec *Decoder) Decode(e interface{}) error
Decode reads the next value from the input stream and stores it in the data represented by the       
empty interface value.
If e is nil, the value will be discarded. 
Otherwise, the value underlying e must be a pointer to the correct type for the next data item received.
If the input is at EOF, Decode returns io.EOF and does not modify e.

i didn't understand nothing in this documentation . what they mean by ( reads the next value from the input stream ) they are one data that we could send it's a struct or a map but not many .what they mean by If e is nil, the value will be discarded. please expert explain to me i'am disasperate all day and ididn't find nothing

You can call encode multiple times on the same encoder. Similarly you can call decode multiple times on the same decoder.

This is true of the JSON encoder/decoder as well.
