| RETURNS | DESCRIPTION |
|---|---|
Body |
Encode the BodyElement into a byte string.
The default implementation does nothing. Subclasses that represent data or instructions should override this method.
| virtual void encode | ( | std::string & bytes, | |
| const Memory * memory | ); |
| PARAMETER | DESCRIPTION |
|---|---|
bytes |
The byte string to encode into. |
memory |
The memory context for encoding. |
Evaluate the BodyElement in a given context.
Subclasses must implement this method.
If an error occurs during evaluation, either an error should be reported via DiagnosticOutput and the BodyElement marked as invalid, or an exception should be thrown.
| virtual std::optional< Body > evaluate | ( | const EvaluationContext & context | ); |
| PARAMETER | DESCRIPTION |
|---|---|
context |
The evaluation context. |
| RETURNS | DESCRIPTION |
|---|---|
std::optional< Body > |
The Body to replace this BodyElement with, {} if no replacement is needed. |
Serialize the BodyElement to a stream.
Subclasses must implement this method.
| virtual void serialize | ( | std::ostream & stream, | |
| const std::string & prefix | ) const; |
| PARAMETER | DESCRIPTION |
|---|---|
stream |
The stream to serialize to. |
prefix |
The prefix for each line of the serialized output. |
