Returns if the function bounds for symbols in this symbol file are likely accurate.
The unwinder can emulate the instructions of functions to understand prologue/epilogue code sequences, where registers are spilled on the stack, etc. This feature relies on having the correct start addresses of all functions. If the ObjectFile has a way to tell that symbols have been stripped and there's no way to reconstruct start addresses (e.g. LC_FUNCTION_STARTS on Mach-O, or eh_frame unwind info), the ObjectFile should indicate that assembly emulation should not be used for this module.
It is uncommon for this to return false. An ObjectFile needs to be sure that symbol start addresses are unavailable before false is returned. If it is unclear, this should return true.

The object file should be able to calculate its type by looking at its file header and possibly the sections or other data in the object file.
The file type is used in the debugger to help select the correct plug- ins for the job at hand, so this is important to get right. If any eTypeXXX definitions do not match up with the type of file you are loading, please feel free to add a new enumeration value.

Returns base address of this object file.
This also sometimes referred to as the "preferred load address" or the "image base address". Addresses within object files are often expressed relative to this base. If this address corresponds to a specific section (usually the first byte of the first section) then the returned address will have this section set. Otherwise, the address will just have the offset member filled in, indicating that this represents a file address.

Return true if this file is a dynamic link editor (dyld)
Often times dyld has symbols that mirror symbols in libc and other shared libraries (like "malloc" and "free") and the user does not want to stop in these shared libraries by default.
