Metamethods
- Double:__index (key)
-
Lookup of missing class members.
Parameters:
- key string lookup of member
Returns:
anyRaises:
on wrong arguments - Double:__call (...)
-
Get arguments for a functionlike call.
Parameters:
- ... vararg pass on to dispatch
Returns:
self
Methods
- Double:create (...)
-
Create a new instance.
Parameters:
- ...
vararg
forwarded to
_init()
Returns:
self - ...
vararg
forwarded to
- Double:_init (...)
-
Initialize a new instance.
Parameters:
- ... vararg shifted into the values list
Returns:
self - Double:dispatch (...)
-
Dispatch arguments
Parameters:
- ... vararg argumnts to be stored for later retrieval
Returns:
selfRaises:
on wrong arguments - Double:setName (name)
-
Set identifying name
Parameters:
- name nil or string used for error reports treturn self
Raises:
on wrong arguments - Double:hasName ()
- Has set name. treturn boolean
- Double:setLevel (level)
-
Set stack level.
Parameters:
- level nil or number where to start reporting treturn self
Raises:
on wrong arguments - Double:hasLevel ()
- Has set level. treturn boolean
- Double:setOnEmpty (func)
-
Set on empty fallback.
Parameters:
- func nil or function fallback to be used in place of precomputed values treturn self
Raises:
on wrong arguments - Double:hasOnEmpty ()
- Has set empty fallback. treturn boolean
- Double:isEmpty ()
-
Is the list of values empty.
Note that the internal structure is non-empty even if a nil
is shifted into the values list.
Returns:
boolean whether the internal values list has length zero - Double:depth ()
-
What is the depth of the internal values list.
Note that the internal structure has a depth even if a nil
is shifted into the values list.
Returns:
number how deep is the internal structure - Double:layout ()
-
Get the layout of the values list.
This method is used for testing to inspect which types of objects exists in the values list.
Returns:
table description of the internal structure - Double:add (...)
-
Add value(s) to the list of values.
Parameters:
- ...
Returns:
self facilitate chaining - Double:remove (num)
-
Remove value from the list of values.
Parameters:
- num
Returns:
any item that can be put on the internal structure - Double:stub ()
-
Return a stub function for the object.
Each call to the returned closure will remove one case of values from the internal structure.
Returns:
closure - Double:hasStub ()
- Has set stub function. treturn boolean
- Double:export ()
-
Export a list of all the contents.
Returns:
table list of values - Double:flush ()
-
Flush all the contents.
Note that this clears the internal storage.
Returns:
table list of values
