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

#names : ArrayLiteral(MacroId)
Returns an array with each separate part of this path.
-
#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. -
#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 aNilLiteral
. -

Instance Method Detail
Returns true
if this is a global path (starts with ::
)
DEPRECATED Use #global?
instead
Returns an array with each separate part of this path.
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.
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
.
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.
