Having the following enum definition
<enum name="Enum1" encodingType="uint8">
<validValue name="Val1">0</validValue>
<validValue name="Val2">1</validValue>
<validValue name="Val3">2</validValue>
</enum>
and message with single constant field
<message name="Msg1" id="1" description="TestMessage">
<field name="field1" id="20" type="uint8" presence="constant" valueRef="Enum1.Val2"/>
</message>
generates code that serializes the field:
std::uint8_t field1() const
{
return (*((std::uint8_t *)(m_buffer + m_offset + 0)));
}
Msg1 &field1(const std::uint8_t value)
{
*((std::uint8_t *)(m_buffer + m_offset + 0)) = (value);
return *this;
}
while realizing that the field is constant:
static const char *field1MetaAttribute(const MetaAttribute::Attribute metaAttribute) SBE_NOEXCEPT
{
switch (metaAttribute)
{
case MetaAttribute::EPOCH: return "unix";
case MetaAttribute::TIME_UNIT: return "nanosecond";
case MetaAttribute::SEMANTIC_TYPE: return "";
case MetaAttribute::PRESENCE: return "constant"; // <----- HERE
}
return "";
}
The only difference from #528 is that the type of the field is specified "uint8" directly instead of "Enum1".
