## Detailed Description

template<class TInt>
class zypp::bit::BitField< TInt >

An integral type used as BitField.

Most methods exist as templated and nontemplated version. The nontemplated operates on the complete BitField, while the tamplated ones are restricted to the given Range.

BitField<char> bf; // 00000000
typedef Range<char,2,3> SubField; // bits 2,3,4 in a char field
bf<SubField>.assign( -1 ); // assign SubField in -1
// to SubField in bf.
// 00011100
bf.assign( -1 ); // assign -1 to bf
// 11111111
bf<SubField>.assign( 0 ); // 11100011
zypp::bit::BitField::assign
BitField & assign(TInt rhs)
Assign Range in rhs to this.
