C++ (Cpp) SBValue Examples

Example #1

File: SBTypeSummary.cpp Project: tony/lldb

bool
SBTypeSummary::DoesPrintValue (lldb::SBValue value)
{
    if (!IsValid())
        return false;
    lldb::ValueObjectSP value_sp = value.GetSP();
    return m_opaque_sp->DoesPrintValue(value_sp.get());
}

Example #2

File: LLDBVariable.cpp Project: GaganJotSingh/codelite

void LLDBVariable::DoInitFromLLDBValue(lldb::SBValue value)
{
    SetName(value.GetName());
    SetType(value.GetTypeName());
    SetSummary(value.GetSummary());
    SetValue(value.GetValue());
    SetValueChanged(value.GetValueDidChange());
    SetLldbId(value.GetID());

    if(value.MightHaveChildren()) {
        m_hasChildren = true;
    }
}

Example #3

File: MICmnLLDBUtilSBValue.cpp Project: cemeyer/freebsd-base-graphics

CMIUtilString
CMICmnLLDBUtilSBValue::ReadCStringFromHostMemory(lldb::SBValue &vrValue, const MIuint vnMaxLen) const
{
    std::string result;
    lldb::addr_t addr = vrValue.GetLoadAddress(), end_addr = addr + vnMaxLen * sizeof(charT);
    lldb::SBProcess process = CMICmnLLDBDebugSessionInfo::Instance().GetProcess();
    lldb::SBError error;
    while (addr < end_addr)

        result.append(CMIUtilString::ConvertToPrintableASCII(ch));
