blark.transform.Function

class blark.transform.Function(access: AccessSpecifier | None, name: Token, return_type: SimpleSpecification | IndirectSimpleSpecification | None, declarations: List[VariableDeclarationBlock], body: StatementList | None, meta: Meta | None = None)[source]

Bases: object

A full function block type declaration, with nested variable declaration blocks.

An implementation is optional, but END_FUNCTION is required.

Examples:

FUNCTION FuncName : INT
    VAR_INPUT
        iValue : INT := 0;
    END_VAR
    FuncName := iValue;
END_FUNCTION

Lark grammar

This class is used by the following grammar rules:

function_declaration

function_declaration: "FUNCTION"i [ access_specifier ] derived_function_name [ ":" indirect_simple_specification ] ";"* [ function_var_block+ ] [ function_body ] "END_FUNCTION"i ";"*

Methods

`__init__`(access, name, return_type, ...[, meta])
`from_lark`(access, name, return_type, *remainder)
