Public Member Functions | |
| constexpr | KeyMatrixPosition ()=default |
| Creates an invalid key matrix position, which can be used when a key does not exist on a particular keyboard. More... | |
| constexpr | KeyMatrixPosition (byte rowCol_) |
| Creates a key matrix position from a byte: the row is stored in the high nibble, the column is stored in the low nibble. More... | |
| constexpr | KeyMatrixPosition (unsigned row, unsigned col) |
| Creates a key matrix position with a given row and column. More... | |
| constexpr bool | isValid () const |
| Returns true iff this position is valid. More... | |
| constexpr unsigned | getRow () const |
| Returns the matrix row. More... | |
| constexpr unsigned | getColumn () const |
| Returns the matrix column. More... | |
| constexpr byte | getRowCol () const |
| Returns the matrix row and column combined in a single byte: the column is stored in the lower 3 bits, the row is stored in the higher bits. More... | |
| constexpr unsigned | getMask () const |
| Returns a mask with the bit corresponding to this position's column set, all other bits clear. More... | |
