checksum

public static int checksum(byte[] data,
                           boolean isEntireMessage)

Calculates the checksum for the given data.

Parameters:

data - the data to calculate the checksum on

isEntireMessage - specifies whether the data is an entire message; if true, and it ends with a checksum field, that checksum field is excluded from the current checksum calculation

Returns:

the calculated checksum

checksum

public static int checksum(Charset charset,
                           String data,

Calculates the checksum for the given data.

Parameters:

charset - the charset used in encoding the data

data - the data to calculate the checksum on

isEntireMessage - specifies whether the data is an entire message; if true, and it ends with a checksum field, that checksum field is excluded from the current checksum calculation

Returns:

the calculated checksum

checksum

public static int checksum(String message)

Calculates the checksum for the given message (excluding existing checksum field, if one exists). The global charset is used.
