Class InvokeExpr

Invocation expression.

This can be regular function call, or method call on an object. If it is a method call, use InvokeExpr.getBase | getBase to get the object, and InvokeExpr.getTarget | getTarget to get the method name. Otherwise, InvokeExpr.getBase | getBase will return undefined, and you can use InvokeExpr.getTarget | getTarget to get the function name.

argCount

  • get argCount(): number

    Get the number of arguments passed to the function.

    Returns number

    The number of arguments.

args

  • get args(): Value[]

    Get all arguments passed to the function.

    Returns Value[]

    The arguments passed to the function.

base

  • get base(): undefined | Value

    Get the base object of the invocation, which is the object that the method is called on.

    Returns undefined | Value

    The base object, or undefined if it is a regular function call.

code

  • get code(): string

    Get the original line of code in the source file.

    All values in one node share the same code.

    Returns string

    The original

id

  • get id(): number

    Get the id of the vertex in the graph database this value represents.

    Returns number

  • set id(id: number): void
    Internal

    Parameters

    • id: number

    Returns void

identifier

  • get identifier(): string

    The syntax component identifier, i.e. ArkAssignStmt.

    Returns string

    The identifier.

node

  • get node(): CodeNode

    Get the node in the graph database this value is associated with.

    Value only represents the AST of the node in the database, use this method to get the complete node, see CodeNode | CodeNode for more information.

    FIXME: All values should be associated with CodeNode, so no type check is performed here.

    Returns CodeNode

    The complete node in the graph database this value is associated with.

supported

  • get supported(): boolean

    Values that cannot be parsed from AST will be marked as unsupported. Usually, only InvalidValue should be marked as unsupported.

    Returns boolean

    Whether this value is supported by the current implementation.

target

  • get target(): string

    Get the target of the invocation, which is the function name that is being called.

    Returns string

    The target function name.

type

  • get type(): Type

    By default, the value has an invalid type, see InvalidType.

    Returns Type

    The type of this value.

  • set type(type: Type): void

    Parameters

    • type: Type

    Returns void

Methods

stream

  • stream(): Stream<Value>

    This method is used to get the stream representation of this value. It depends on the implementation of the elements method.

    See Stream for stream operations.

    Returns Stream<Value>

    A stream of values.
