Detailed Description

Generate CRC-32 checksums.

A CRC-32 is a checksum that is used to verify the integrity of data. A matching CRC-32 does not guarantee the data is uncorrupted, but it provides a very high degree of confidence.

Member Function Documentation

compare()

virtual int utl::CRC32::compare ( const Object &  rhs ) const

virtual

Compare with another object.

If no overridden version succeeds in doing the comparison, then an attempt will be made to re-start the comparison process using one or both of the objects' keys. Usually, an override of compare() should call the superclass's compare() if it doesn't know how to compare itself with the rhs object.

See also

getKey

Returns

< 0 if self < rhs, 0 if self = rhs, > 0 if self > rhs

Parameters

rhs	object to compare with

Reimplemented from utl::Object.

copy()

virtual void utl::CRC32::copy ( const Object &  rhs )

virtual

Copy another instance.

When you override copy(), you should usually call the superclass's copy().

Parameters

rhs	object to copy

Reimplemented from utl::Object.

serialize()

virtual void utl::CRC32::serialize ( Stream &  stream, uint_t  io, uint_t  mode = ser_default  )

virtual

Serialize to or from a stream.

This is the only virtual method for serialization. You must override this in any class that has data to be serialized, and ensure that the superclass's serialize() gets called.

Parameters

stream	stream to serialize from/to
io	see utl::io_t
mode	see utl::serialize_t

Reimplemented from utl::Object.

toString()

virtual String utl::CRC32::toString ( ) const

virtual

Return a string representation of self.

Reimplemented from utl::Object.

add()

void utl::CRC32::add

(

byte_t

ch

)

Update the CRC-32 code for a given byte.

clear()

void utl::CRC32::clear ( )

inline

Clear/reset the CRC-32 code.

Definition at line 43 of file CRC32.h.

References utl::uint32_t_max.

get()

uint_t utl::CRC32::get ( ) const

inline

Get the CRC-32 code.
