C++ (Cpp) CParameterAccessContext::getParameterBlackboard Examples

Example #1

File: InstanceConfigurableElement.cpp Project: DanAlbert/parameter-framework

bool CInstanceConfigurableElement::sync(CParameterAccessContext& parameterAccessContext) const
{
    if (!parameterAccessContext.getAutoSync()) {

        // AutoSync is disabled, do not perform the sync.
        // This is not an error, but the expected behavior so return true anyway.
        return true;
    }
    ISyncer* pSyncer = getSyncer();

    if (!pSyncer) {

        parameterAccessContext.setError("Unable to synchronize modification. No Syncer object associated to configurable element:");

    }

        parameterAccessContext.setError(strError);

        return false;
    }

Example #2

File: Parameter.cpp Project: zhongxingzhi/parameter-framework

// Used for simulation and virtual subsystems
void CParameter::setDefaultValues(CParameterAccessContext& parameterAccessContext) const
{
    // Get default value from type
    uint32_t uiDefaultValue = static_cast<const CParameterType*>(getTypeElement())->getDefaultValue();

    // Write blackboard
    CParameterBlackboard* pBlackboard = parameterAccessContext.getParameterBlackboard();

    // Beware this code works on little endian architectures only!
    pBlackboard->writeInteger(&uiDefaultValue, getSize(), getOffset() - parameterAccessContext.getBaseOffset(), parameterAccessContext.isBigEndianSubsystem());
}

Example #3

File: Parameter.cpp Project: zhongxingzhi/parameter-framework

bool CParameter::doGet(type& value, uint32_t uiOffset, CParameterAccessContext& parameterAccessContext) const
{
    uint32_t uiData = 0;

    const CParameterBlackboard* pBlackboard = parameterAccessContext.getParameterBlackboard();

    // Beware this code works on little endian architectures only!
    pBlackboard->readInteger(&uiData, getSize(), uiOffset, parameterAccessContext.isBigEndianSubsystem());

    return static_cast<const CParameterType*>(getTypeElement())->fromBlackboard(value, uiData, parameterAccessContext);
}

Example #4

File: Parameter.cpp Project: zhongxingzhi/parameter-framework

bool CParameter::doSet(type value, uint32_t uiOffset, CParameterAccessContext& parameterAccessContext) const
{
    uint32_t uiData;

    // Beware this code works on little endian architectures only!
