Constructors

constructor

Properties

Optional context

context?: ASTContext

Current tree context of the node

id

id: number

Unique identifier number for the node in the tree context

literals

literals: string[]

An array representing literals of the pragma identifier and value parts, e.g. [ "solidity", "^", "0.4", ".15" ].

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.

Accessors

children

firstChild

  • get firstChild(): undefined | ASTNode

  • Returns the first immediate child of the node, or undefined if the node has no children.

    Returns undefined | ASTNode

lastChild

  • get lastChild(): undefined | ASTNode

  • Returns the last immediate child of the node, or undefined if the node has no children.

    Returns undefined | ASTNode

nextSibling

  • get nextSibling(): undefined | ASTNode

  • Returns the node immediately following the current one in its parent's children.

    Returns undefined if the current node is the last child in its parent's children.

    Returns undefined | ASTNode

previousSibling

  • get previousSibling(): undefined | ASTNode

  • Returns the node immediately preceding the current one in its parent's children.

    Returns undefined if the current node is the first child in its parent's children.

    Returns undefined | ASTNode

requiredContext

root

sourceInfo

type

  • get type(): string

  • Type of the AST node

    Returns string

vIdentifier

vValue

Methods

acceptChildren

extractSourceFragment

  • extractSourceFragment(source): Uint8Array

  • Extracts and returns substring from source, that corresponds to src property value of the current node.

    In other words, returns corresponding code fragment substring.

    Parameters

    • source: Uint8Array

    Returns Uint8Array

getParents

getParentsBySelector

print

  • print(depth?): string

  • Returns string representation of the node properties.

    Parameters

    • depth: number = 0

      The number of children node levels to output

    Returns string

walk
