abstract fun readLongIntList(bitLength: Int): MutableList<Long!>! (source)
Read a list of two's-compliment long int values from the SSZ source.
bitLength - Int: The bit length of the integers to read (a multiple of 8).
InvalidSSZTypeException - If the next SSZ value is not a list, there are insufficient encoded bytes for the desired bit length or any value in the list, or any decoded value was too large to fit into a long.
EndOfSSZException - If there are no more SSZ values to read.
Return
MutableList<Long!>!: A list of longs.
