Member Function Documentation

virtual long long decaf::util::zip::CRC32::getValue ( ) const

virtual

Returns

the current checksum value.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::CRC32::reset ( )

virtual

Reset the checksum to its initial value.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::CRC32::update ( const std::vector< unsigned char > &  buffer )

virtual

Updates the current checksum with the specified vector of bytes.

Parameters

buffer

The buffer to read the updated bytes from.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::CRC32::update ( const std::vector< unsigned char > &  buffer, int  offset, int  length  )

virtual

Updates the current checksum with the specified array of bytes.

Parameters

buffer	The buffer to read the updated bytes from.
offset	The position in the buffer to start reading.
length	The amount of data to read from the byte buffer.

Exceptions

IndexOutOfBoundsException

if offset + length > size of the buffer.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::CRC32::update ( const unsigned char *  buffer, int  size, int  offset, int  length  )

virtual

Updates the current checksum with the specified array of bytes.

Parameters

buffer	The buffer to read the updated bytes from.
size	The size of the passed buffer.
offset	The position in the buffer to start reading.
length	The amount of data to read from the byte buffer.

Exceptions

NullPointerException	if the passed buffer is NULL.
IndexOutOfBoundsException	if offset + length > size of the buffer.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::CRC32::update ( int  byte )

virtual

Updates the current checksum with the specified byte value.

Parameters

byte	The byte value to update the current Checksum with (0..255).

Implements decaf::util::zip::Checksum.
