Summary

[Expand] Inherited Constants
From interface com.pnfsoftware.jeb.core.units.code.android.ir.IDElement boolean DEFAULT_COMPARE_WITH_FULL_EQUALITY Determine whether hashCode and equals use all the IR expression elements, including metadata like: - physical offset - data map This value is set to false and should not be modified.
