# Class SBFrame

source code

    Represents one of the stack frames associated with a thread.
    SBThread contains SBFrame(s). For example (from test/lldbutil.py),

    def print_stacktrace(thread, string_buffer = False):
        '''Prints a simple stack trace of this thread.'''

        ...

        for i in range(depth):
            frame = thread.GetFrameAtIndex(i)
            function = frame.GetFunction()

            load_addr = addrs[i].GetLoadAddress(target)
            if not function:
                file_addr = addrs[i].GetFileAddress()
                start_addr = frame.GetSymbol().GetStartAddress().GetFileAddress()
                symbol_offset = file_addr - start_addr
                print >> output, '  frame #{num}: {addr:#016x} {mod}`{symbol} + {offset}'.format(
                    num=i, addr=load_addr, mod=mods[i], symbol=symbols[i], offset=symbol_offset)
            else:
                print >> output, '  frame #{num}: {addr:#016x} {mod}`{func} at {file}:{line} {args}'.format(
                    num=i, addr=load_addr, mod=mods[i],
                    func='%s [inlined]' % funcs[i] if frame.IsInlined() else funcs[i],
                    file=files[i], line=lines[i],
                    args=get_args_as_string(frame, showFuncName=False) if not frame.IsInlined() else '()')

        ...

    And,

        for frame in thread:
            print frame

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::SBFrame self) -> SBFrame __init__(lldb::SBFrame self, SBFrame rhs) -> SBFrame Overrides: object.__init__

### GetCFA(self) | source code
GetCFA(SBFrame self) -> lldb::addr_t Get the Canonical Frame Address for this stack frame. This is the DWARF standard's definition of a CFA, a stack address that remains constant throughout the lifetime of the function. Returns an lldb::addr_t stack address, or LLDB_INVALID_ADDRESS if the CFA cannot be determined.

### GetBlock(self) | source code
GetBlock(SBFrame self) -> SBBlock Gets the deepest block that contains the frame PC. See also GetFrameBlock().

### GetFunctionName(self, *args) | source code
    GetFunctionName(SBFrame self) -> str const
    GetFunctionName(SBFrame self) -> str const *

    Get the appropriate function name for this frame. Inlined functions in
    LLDB are represented by Blocks that have inlined function information, so
    just looking at the SBFunction or SBSymbol for a frame isn't enough.
    This function will return the appropriate function, symbol or inlined
    function name for the frame.

    This function returns:
    - the name of the inlined function (if there is one)
    - the name of the concrete function (if there is one)
    - the name of the symbol (if there is one)
    - NULL

    See also IsInlined().

### IsInlined(self, *args) | source code
IsInlined(SBFrame self) -> bool IsInlined(SBFrame self) -> bool Return true if this frame represents an inlined function. See also GetFunctionName().

### EvaluateExpression(self, *args) | source code
EvaluateExpression(SBFrame self, str const * expr) -> SBValue EvaluateExpression(SBFrame self, str const * expr, lldb::DynamicValueType use_dynamic) -> SBValue EvaluateExpression(SBFrame self, str const * expr, lldb::DynamicValueType use_dynamic, bool unwind_on_error) -> SBValue EvaluateExpression(SBFrame self, str const * expr, SBExpressionOptions options) -> SBValue The version that doesn't supply a 'use_dynamic' value will use the target's default.

### GetFrameBlock(self) | source code
GetFrameBlock(SBFrame self) -> SBBlock Gets the lexical block that defines the stack frame. Another way to think of this is it will return the block that contains all of the variables for a stack frame. Inlined functions are represented as SBBlock objects that have inlined function information: the name of the inlined function, where it was called from. The block that is returned will be the first block at or above the block for the PC (SBFrame::GetBlock()) that defines the scope of the frame. When a function contains no inlined functions, this will be the top most lexical block that defines the function. When a function has inlined functions and the PC is currently in one of those inlined functions, this method will return the inlined block that defines this frame. If the PC isn't currently in an inlined function, the lexical block that defines the function is returned.

### GetVariables(self, *args) | source code
GetVariables(SBFrame self, bool arguments, bool locals, bool statics, bool in_scope_only) -> SBValueList GetVariables(SBFrame self, bool arguments, bool locals, bool statics, bool in_scope_only, lldb::DynamicValueType use_dynamic) -> SBValueList GetVariables(SBFrame self, SBVariablesOptions options) -> SBValueList The version that doesn't supply a 'use_dynamic' value will use the target's default.

### FindVariable(self, *args) | source code
FindVariable(SBFrame self, str const * var_name) -> SBValue FindVariable(SBFrame self, str const * var_name, lldb::DynamicValueType use_dynamic) -> SBValue The version that doesn't supply a 'use_dynamic' value will use the target's default.

### GetValueForVariablePath(self, *args) | source code
    GetValueForVariablePath(SBFrame self, str const * var_path) -> SBValue
    GetValueForVariablePath(SBFrame self, str const * var_path, lldb::DynamicValueType use_dynamic) -> SBValue

    Get a lldb.SBValue for a variable path.

    Variable paths can include access to pointer or instance members:
        rect_ptr->origin.y
        pt.x
    Pointer dereferences:
        *this->foo_ptr
        **argv
    Address of:
        &pt
        &my_array[3].x
    Array accesses and treating pointers as arrays:
        int_array[1]
        pt_ptr[22].x

    Unlike EvaluateExpression() which returns lldb.SBValue objects
    with constant copies of the values at the time of evaluation,
    the result of this function is a value that will continue to
    track the current value of the value as execution progresses
    in the current frame.

### FindValue(self, *args) | source code
FindValue(SBFrame self, str const * name, lldb::ValueType value_type) -> SBValue FindValue(SBFrame self, str const * name, lldb::ValueType value_type, lldb::DynamicValueType use_dynamic) -> SBValue Find variables, register sets, registers, or persistent variables using the frame as the scope. The version that doesn't supply a 'use_dynamic' value will use the target's default.

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