class DWARFExpression::Operation

Declaration

class DWARFExpression::Operation { /* full declaration omitted */ };

Description

This class represents an Operation in the Expression. Each operation can have up to 2 oprerands. An Operation can be in Error state (check with isError()). This means that it couldn't be decoded successfully and if it is the case, all others fields contain undefined values.
