# Class SBAddress

source code

    A section + offset based address class.

    The SBAddress class allows addresses to be relative to a section
    that can move during runtime due to images (executables, shared
    libraries, bundles, frameworks) being loaded at different
    addresses than the addresses found in the object file that
    represents them on disk. There are currently two types of addresses
    for a section:
        o file addresses
        o load addresses

    File addresses represents the virtual addresses that are in the 'on
    disk' object files. These virtual addresses are converted to be
    relative to unique sections scoped to the object file so that
    when/if the addresses slide when the images are loaded/unloaded
    in memory, we can easily track these changes without having to
    update every object (compile unit ranges, line tables, function
    address ranges, lexical block and inlined subroutine address
    ranges, global and static variables) each time an image is loaded or
    unloaded.

    Load addresses represents the virtual addresses where each section
    ends up getting loaded at runtime. Before executing a program, it
    is common for all of the load addresses to be unresolved. When a
    DynamicLoader plug-in receives notification that shared libraries
    have been loaded/unloaded, the load addresses of the main executable
    and any images (shared libraries) will be  resolved/unresolved. When
    this happens, breakpoints that are in one of these sections can be
    set/cleared.

    See docstring of SBFunction for example usage of SBAddress.

Method Details | [hide private]

### __setattr__(self, name, value) | source code
x.__setattr__('name', value) <==> x.name = value Overrides: object.__setattr__ (inherited documentation)

### __repr__(self) (Representation operator) | source code
repr(x) Overrides: object.__repr__ (inherited documentation)

### __init__(self, *args) (Constructor) | source code
__init__(lldb::SBAddress self) -> SBAddress __init__(lldb::SBAddress self, SBAddress rhs) -> SBAddress __init__(lldb::SBAddress self, SBSection section, lldb::addr_t offset) -> SBAddress __init__(lldb::SBAddress self, lldb::addr_t load_addr, SBTarget target) -> SBAddress Create an address by resolving a load address using the supplied target. Overrides: object.__init__

### GetSymbolContext(self, *args) | source code
GetSymbolContext(SBAddress self, uint32_t resolve_scope) -> SBSymbolContext GetSymbolContext() and the following can lookup symbol information for a given address. An address might refer to code or data from an existing module, or it might refer to something on the stack or heap. The following functions will only return valid values if the address has been resolved to a code or data address using 'void SBAddress::SetLoadAddress(...)' or 'lldb::SBAddress SBTarget::ResolveLoadAddress (...)'.

### GetModule(self) | source code
    GetModule(SBAddress self) -> SBModule

    GetModule() and the following grab individual objects for a given address and
    are less efficient if you want more than one symbol related objects.
    Use one of the following when you want multiple debug symbol related
    objects for an address:
       lldb::SBSymbolContext SBAddress::GetSymbolContext (uint32_t resolve_scope);
       lldb::SBSymbolContext SBTarget::ResolveSymbolContextForAddress (const SBAddress &addr, uint32_t resolve_scope);
    One or more bits from the SymbolContextItem enumerations can be logically
    OR'ed together to more efficiently retrieve multiple symbol objects.

### __str__(self) (Informal representation operator) | source code
__str__(SBAddress self) -> PyObject * Overrides: object.__str__
