readRawVarint32

public static Pair<Integer,Integer> readRawVarint32(byte[] input,
                                                    int offset)
                                             throws IOException

Reads a varInt value stored in an array.

Parameters:

input - Input array where the varInt is available

offset - Offset in the input array where varInt is available

Returns:

A pair of integers in which first value is the actual decoded varInt value and second value as number of bytes taken by this varInt for it's storage in the input array.

Throws:

IOException

toShort
