Detailed Description
Abstract class for converting native constants to addresses.
This class is used if there is a special calculation to get from a constant embedded in the code being analyzed to the actual Address being referred to. This is used especially in the case of a segmented architecture, where "near" pointers must be extended to a full address with implied segment information.

Virtual destructor
The main resolver method.
Given a native constant in a specific context, resolve what address is being referred to. The constant can be a partially encoded pointer, in which case the full pointer encoding is recovered as well as the address. Whether or not a pointer is partially encoded or not is determined by the sz parameter, indicating the number of bytes in the pointer. A value of -1 here indicates that the pointer is known to be a full encoding.
- Parameters
-
val is constant to be resolved to an address sz is the size of val in context (or -1). point is the address at which this constant is being used fullEncoding is used to hold the full pointer encoding if val is a partial encoding
- Returns
- the resolved Address
Implemented in SegmentedResolver.
