class JITLinkerBase

Declaration

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

Description

Base class for a JIT linker. A JITLinkerBase instance links one object file into an ongoing JIT session. Symbol resolution and finalization operations are pluggable, and called using continuation passing (passing a continuation for the remaining linker work) to allow them to be performed asynchronously.
