Detailed Description

Adds a word size attribute to IntegerValue.

The word size really only acts as an attribute that is carried along with the integer value. It doesn't affect the actual value at all. However, you can use the getWordSizeMask() method to mask off bits that should not be there.

The word size defaults to a 32-bit word.

Member Function Documentation

size_t SizedIntegerValue::getSize ( ) const
virtual

Returns a varying size depending on the word size attribute.

Reimplemented from elftosb::IntegerValue.

uint32_t SizedIntegerValue::getWordSizeMask ( ) const

Returns a 32-bit mask value dependant on the word size attribute.

The resulting mask can be used to truncate the integer value to be certain it doesn't extend beyond the associated word size.
