示例1: SetValue
//--------------------------------------------------------------------------------------
HRESULT BoundValueTable::SetValue( BindAddressHandle handle, const Value* pValue )
{
Binding* binding = NULL;
if(!GetOrAddBinding(&binding, handle, false))
return E_FAIL;
if(binding->bPromoteToParent)
{
BindAddressInfo info;
BindAddressHelper::GetInfo( handle, &info );
Sas::Host::Out( Sas::LEVEL_ERROR, L"Cannot set value on BindAddress that is promoted to parent, %s", info.StrAddress.c_str() );
return E_FAIL;
}
const Value*& pOldValue = binding->pValue;
// If the current value is equal to the value being set, nothing needs to be done
if( Value::Equal( pOldValue, pValue ) )
return S_OK;
// The old value needs to be deallocated before proceeding with the rest of the set.
SAFE_DELETE(pOldValue);
// Clone and store the new value
Value* pNewValue = NULL;
if( NULL != pValue )
{
pNewValue = pValue->Clone();
if( NULL == pNewValue )
return E_OUTOFMEMORY;
}
// Set the value
binding->pValue = pNewValue;
binding->CallListeners( handle );
return S_OK;
