Use the functions described below to generates a checksum for a supplied argument.

cksumReset

Resets the cksum info and prepare to start new cksum calculation.

Code Block
void cksumReset()

cksumUpdate

Updates the cksum using the specified array of bytes.

Code Block
void cksumUpdate( bytearray data )

Parameter	Description
`bytearray`	Any bytearray
Returns	Nothing

Gets the result of cksum (using all data that has been entered into cksumUpdate). Returns an unsigned 32 bit integer (as a long).

Code Block
long cksumResult()

Gets the total length of all data that has been entered into cksumUpdate.

Code Block
long cksumLength()

Info

title	Example - cksum

Simple APL code (Disk_1 is the input agent in the workflow)

Code Block
beginBatch { cksumReset(); } consume { cksumUpdate( input ); } endBatch { debug( ((string)cksumResult()) + " " + cksumLength() + " " + ((string)mimGet("Disk_1","Source Filename")) ); }

Function that computes the CRC-32 of supplied argument.

Code Block
long crc32( any source )

Parameter	Description
`source`	The argument used to compute the CRC-32. Supported types are string, bytearray and number types.
Returns	The CRC-32 value
