Detailed Description

Reading through it will only return bits within the range.

The length of the range may not be larger than sizeof(I)*8.

Definition at line 161 of file Instruction.h.

Constructor & Destructor Documentation

◆ BitArrayRange()

etiss::instr::BitArrayRange::BitArrayRange	(	unsigned	endindex_included,
		unsigned	startindex_included
	)

Attention: startindex_included MUST be the higher valued index. Only exception is for zero length ranges where startindex_included+1==endindex_included

Definition at line 166 of file Instruction.cpp.

Member Function Documentation

◆ end()

BitArray::size_type etiss::instr::BitArrayRange::end ( )

lowest bit of the range (included).

Attention: for zero length ranges end() equals start()+1

Definition at line 189 of file Instruction.cpp.

References endpos.

◆ read()

I etiss::instr::BitArrayRange::read ( const BitArray & ba )

reads bits from the range to the return value starting at the lsb.

higher bits are set to zero
