Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def defaults_to_nil? : Bool #

If this is a pointer-type, does it default to nullptr in C++?


[View source]
def has_default? : Bool #

Does this argument have a default value?


[View source]
def has_exposed_default? #

Does this argument have an exposed default value?


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def merge(other : Argument) #

Merges this argument with other. Only merges the name, defaultness, its value and nil-ability. For the value, this argument takes precedence over other. The name is taken from other, as Crystal expects the arguments of an overriding method to be named like those of the overridden one. Unnamed arguments are named by their position.


[View source]
def name : String #

Name of this argument.


[View source]
def nilable? : Bool #

Assume that if the argument defaults to nullptr, that it is nilable.


[View source]
def substitute_type(name : String, with type : Type) : Argument #

Substitutes all uses of name on the type part of this argument with the given type.


[View source]
def substitute_type(replacements : Hash(String, Type)) : Argument #

Performs type substitution on the type part of this argument using the given replacements.


[View source]
def type_equals?(other : Type) #

Checks if the type-part of this equals the type-part of other.


[View source]
def value : DefaultValueTypes | Nil #

Default value for this argument, if an initializer literal is found.


[View source]
def variadic? : Bool #

Is this the vararg (...) argument?


[View source]
def without_default : Argument #

Returns a copy of this argument without a default value.
