GridWorldIterable class

GridWorldIterable is a _GridWorldIterator factory seeded with a GridWorld a ConwayEvolver, and an iteration limit so that attempts to pass the iterable to, say, List.from(iterable) won't explode.

If snapshots is true, each iteration step will return a distinct copy of the world - this is the right thing for making a List.from(iterable) where one expects each element to be distinct/different.

Constructors

GridWorldIterable(GridWorld _gw, {int limit = 50, bool snapshots = false})
Make a iterable with reasonable defaults.

Properties

first GridWorld
Returns the first element. [...]
read-only, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
isEmpty bool
Whether this collection has no elements. [...]
read-only, inherited
isNotEmpty bool
Whether this collection has at least one element. [...]
read-only, inherited
iterator Iterator<GridWorld>
Returns a new Iterator that allows iterating the elements of this Iterable. [...]
read-only, override
last GridWorld
Returns the last element. [...]
read-only, inherited
length int
Returns the number of elements in this. [...]
read-only, inherited
limit int
Avoid infinite iterations with a hard limit.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
single GridWorld
Checks that this iterable has only one element, and returns that element. [...]
read-only, inherited
snapshots bool
If snapshots is false (the default), each iteration returns a pointer to the same underlying (but evolved) world. This is fine if you show the world at that moment. It saves memory. Set snapshots true to get free standing instances at each iteration.
