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 | ( | 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.
| 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 | ( | 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 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.
