public abstract class ELFRelocationContext extends Object
ELF relocation contexts can be registered using the ELFPluginsService.

A relocation context means a type of ELF (e.g. executable, or dynamic file) and an architecture (e.g. Arm). A context consists of one or more relocation applicators.

      elfUnit - ELF unit
      actualImageBase - actual image base
      Returns:
      true if this context can process the file

    • isMappedAtPreferredAddress

      protected boolean isMappedAtPreferredAddress(IELFUnit elfUnit, long actualImageBase)
      Determine whether the file is mapped at its preferred image base.
      Parameters:
      elfUnit - ELF unit
      actualImageBase - actual image base
      Returns:
      true if the actual image base is the preferred image base
