ChecksumBody
Represents a body element that computes a checksum over a range of memory: .checksum algorithm start end [parameters].
| ChecksumBody | ( | std::shared_ptr< ChecksumAlgorithm > algorithm_, | |

| std::unordered_map< Symbol, Expression > parameters | ); |

| virtual Body clone | ( | const CloneContext & context | ) const; |
| PARAMETER | DESCRIPTION |
|---|---|
context |
| 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 body element after all sub-body-elements and sub-expressions have been evaluated.
The default implementation does nothing.
| virtual std::optional< Body > evaluate_process | ( | 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. |
| static Body parse | ( | Tokenizer & tokenizer | ); |
| PARAMETER | DESCRIPTION |
|---|---|
tokenizer |
| RETURNS | DESCRIPTION |
|---|---|
Body |
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. |
Traverse the BodyElement.
This function is used by the default implementations of resolve() and expand_calls(). Unless a subclass overrides both of these methods, it should override traverse().
| virtual void traverse | ( | std::function< void(Body &)> body_callable, | |
| std::function< void(Expression &)> expression_callable | ); |
| PARAMETER | DESCRIPTION |
|---|---|
body_callable |
A callable to apply to each sub-body-element. |
expression_callable |
A callable to apply to each sub-expression. |
