getInt64 method

int getInt64 (int byteOffset, [ Endian endian = Endian.big ])

Returns the (possibly negative) integer represented by the eight bytes at the specified byteOffset in this object, in two's complement binary form.

The return value will be between -2⁶³ and 2⁶³ - 1, inclusive.

Throws RangeError if byteOffset is negative, or byteOffset + 8 is greater than the length of this object.

Implementation

int getInt64(int byteOffset, [Endian endian = Endian.big]);
