Instance Method Detail

def global : BoolLiteral #

Returns true if this is a global path (starts with ::)

DEPRECATED Use #global? instead


[View source]
def global? : BoolLiteral #

Returns true if this is a global path (starts with ::)


[View source]
def names : ArrayLiteral(MacroId) #

Returns an array with each separate part of this path.


[View source]
def resolve : ASTNode #

Resolves this path to a TypeNode if it denotes a type, to the value of a constant if it denotes a constant, or otherwise gives a compile-time error.


[View source]
def resolve? : ASTNode | NilLiteral #

Resolves this path to a TypeNode if it denotes a type, to the value of a constant if it denotes a constant, or otherwise returns a NilLiteral.


[View source]
def types : ArrayLiteral(ASTNode) #

Returns this path inside an array literal. This method exists so you can call #types on the type of a type declaration and get all types, whether it's a Generic, Path or Union.
