Method Detail

convertVectorToByteArray

public static byte[] convertVectorToByteArray(double[] v)

Encodes the double array into a byte array. The first 4 bytes are an integer telling the length of the double array in bytes (i.e. 8*length of vector length). If gzip is set, this exact information will be gzip compressed.

Parameters:

v - The vector to convert into a byte array.

Returns:

The binary vector [4 bytes][rest]: number of bytes encoding the double vector [4 bytes] the actual double vector encoded in bytes [rest]

Throws:

IOException
