Syntax
class FRigVMParserAST : public TSharedFromThis< FRigVMParserAST >
Remarks
The abstract syntax tree parser is the main object to parse a RigVM model graph. It's the memory owner for all expressions and provides functionality for introspection of the tree. The abstract syntax tree is then fed into the RigVMCompiler to generate the byte code for the virtual machine.
