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

__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__

GetBlock(self)

source code 

GetBlock(SBFrame self) -> SBBlock

Gets the deepest block that contains the frame PC.

See also GetFrameBlock().

GetFunctionName(self)

source code 

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 appriopriate 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)

source code 

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

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.
