Expression Struct Reference

AST node to represent a single instruction or an annotation. More...

#include <ast.h>

Detailed Description

AST node to represent a single instruction or an annotation.

Attention

In case of any changes update xreate::ExpressionHints auxiliary helper as well

Expression is a generic building block of syntax tree which is able to hold node data along with child nodes as operands.

Note

For types the expression-like data structure TypeAnnotation is used rather than Expression itself.

Member Data Documentation

bindings

std::vector<std::string> bindings

Exact meaning depends on particular instruction.

As an example, named lists/structs hold field names in bindings

blocks

std::list<CodeScope*> blocks

Child code blocks.

For example, If statement holds TRUE-branch as first and FALSE-branch as second block here
