Methods¶
#==(other : self)
¶
(other : self)
Returns true if this reference is the same as other. Invokes same?.
#c_calling_convention?
¶
Returns self as an External if this Def is an External
that must respect the C calling convention.
#doc : String?
¶
: String?
Returns the doc comment attached to this node. Not every node
supports having doc comments, so by default this returns nil.
#hash(hasher)
¶
(hasher)
#interpret(method : String, args : Array(ASTNode), named_args : Hash(String, ASTNode)?, block : Crystal::Block?, interpreter : Crystal::MacroInterpreter, name_loc : Location?)
¶
(method : String, args : Array(ASTNode), named_args : Hash(String, ASTNode)?, block : Crystal::Block?, interpreter : Crystal::MacroInterpreter, name_loc : Location?)
#match
¶
Yields arg, arg_index, object, object_index corresponding
to arguments matching the given objects, taking into account this
def's splat index.
#min_max_args_sizes
¶
Returns the minimum and maximum number of arguments that must be passed to this method.
