CalculateStrata()

ObjectFile::Strata ObjectFilePECOFF::CalculateStrata ( )

overridevirtual

The object file should be able to calculate the strata of the object file.

Many object files for platforms might be for either user space debugging or for kernel debugging. If your object file subclass can figure this out, it will help with debugger plug-in selection when it comes time to debug.

Returns

The calculated object file strata for the current object file.

Implements lldb_private::ObjectFile.

CalculateType()

ObjectFile::Type ObjectFilePECOFF::CalculateType ( )

overridevirtual

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

The calculated file type for the current object file.

GetAddressByteSize()

uint32_t ObjectFilePECOFF::GetAddressByteSize ( ) const

Gets the address size in bytes for the current object file.

Returns

The size of an address in bytes for the currently selected architecture (and object for archives). Returns zero if no architecture or object has been selected.

GetBaseAddress()

Address ObjectFilePECOFF::GetBaseAddress ( )

overridevirtual

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.

ParseHeader()

bool ObjectFilePECOFF::ParseHeader ( )

Attempts to parse the object header.

This function is used as a test to see if a given plug-in instance can parse the header data already contained in ObjectFile::m_data. If an object file parser does not recognize that magic bytes in a header, false should be returned and the next plug-in can attempt to parse an object file.

Returns

Returns true if the header was parsed successfully, false otherwise.
