PrimaryExpression
- Literal

Constructors

constructor

new Literal(id, src, typeString, kind, hexValue, value, subdenomination?, raw?): Literal
Parameters
- id: number
- src: string
- typeString: string
- kind: LiteralKind
- hexValue: string
- value: string
- Optional subdenomination: EtherUnit | TimeUnit
- Optional raw: any
Returns Literal
Overrides PrimaryExpression.constructor
- Defined in src/ast/implementation/expression/literal.ts:31

Properties

`Optional` context

context?: ASTContext

Current tree context of the node

hexValue

hexValue: string

Hexadecimal representation of value of the literal symbol

id

id: number

Unique identifier number for the node in the tree context

kind

kind: LiteralKind

The type of literal: number, string, bool, hexString or unicodeString.

`Optional` parent

parent?: ASTNode

The AST node that is containing current node

`Optional` raw

raw?: any

Raw original Solc AST node that was used to create current node.

src

src: string

Source mapping data corresponting to the AST node.

The value has format start:length:sourceIndex:

start is the starting index of the corresponding code fragment substring in the source string;
length is the length of corresponding code fragment substring;
sourceIndex is the index number of the source unit (file), that contains the AST node.

To get parsed values, use sourceInfo accessor.

`Optional` subdenomination

subdenomination?: EtherUnit | TimeUnit

The denomination number literal when explicitly specified.

Possible values for time: seconds, minutes, hours, days or weeks (also years for Solidity 0.4.x).

Possible values for ether: wei, gwei or ether (also finney and szabo prior to Solidity 0.7.0).

typeString

typeString: string

Type string, e.g. uint256

value

value: string

Value of the literal symbol
