class InstrumentationMap

Declaration

class InstrumentationMap { /* full declaration omitted */ };

Description

The InstrumentationMap represents the computed function id's and indicated function addresses from an object file (or a YAML file). This provides an interface to just the mapping between the function id, and the function address. We also provide raw access to the actual instrumentation map entries we find associated with a particular object file.
