Instance Method Detail

def [](object) #

Calls one of the #[]? overloads. Raises IndexError instead of returning nil.


[View source]
def []?(index : Int) : UInt32 | Nil #

Returns index-th n of this path.


[View source]
def []?(range : Range) : UPath32 | Nil #

Returns a subview of this path.


[View source]
def append(n : UInt32) : UPath32 #

Inserts n at the back of this path. Returns a modified copy.


[View source]
def each(& : UInt32 -> ) #

Yields each n in this path, left to right.


[View source]
def goto(n : UInt32) : UPath32 #

Makes n the tip of this path. Returns a modified copy. If this path is empty, does nothing.


[View source]
def inspect(io) #

[View source]
def prepend(n : UInt32) : UPath32 #

Inserts n at the front of this path. Returns a modified copy.


[View source]
def prior : UPath32 #

Removes the last n of this path. Returns a modified copy. If this path is empty, does nothing.


[View source]
def rest : UPath32 #

Removes the first n of this path. Returns a modified copy. If this path is empty, does nothing.


[View source]
def size : UInt32 #

Returns the number of ns in this path.


[View source]
def tip : UInt32 #

Returns the last n of this path (its tip), or raises IndexError if this path is empty.


[View source]
def tip? : UInt32 | Nil #

Returns the last n of this path (its tip), or nil if this path is empty.
