public static int decodeToInt(int initialPosition,
                              byte[] data,
                              com.smarttech.toolsense.block.Varint32Decoder.ReturnNextPosition next_position_rtn)

Decodes variable length 32 bit integers encoded using varint 128 encoding from a supplied position in a buffer. The last parameter is an out parameter returning the position in the buffer immediately following the decoded integer.

Parameters:

initialPosition - array index of the first byte of the varint to be decoded

data - the buffer containing a varint

next_position_rtn - out parameter containing the array index of the byte following the decoded int

Returns:

The decoded integer.
