Detailed Description
Class that implements the simplest possible permutation: the identity.Constructor & Destructor Documentation
| Identity::Identity | ( | unsigned int | aWidth | ) | [inline] |
Member Function Documentation
| virtual unsigned int Identity::getWidth | ( | ) | const [inline, virtual] |
Abstract method that returns the number of bits of its domain and range.
Implements Transformation.
| virtual void Identity::operator() | ( | UINT8 * | state | ) | const [inline, virtual] |
Abstract method that applies the transformation onto the parameter state.
- Parameters:
-
state A buffer on which to apply the transformation. The state must have a size of at least ceil(getWidth()/8.0) bytes.
Implements Transformation.
| virtual string Identity::getDescription | ( | ) | const [inline, virtual] |
Abstract method that returns a string with a description of itself.
Implements Transformation.
| virtual void Identity::inverse | ( | UINT8 * | state | ) | const [inline, virtual] |
Abstract method that applies the inverse of the permutation onto the parameter state.
- Parameters:
-
state A buffer on which to apply the inverse permutation. The state must have a size of at least ceil(getWidth()/8.0) bytes.
Implements Permutation.
