An immutable key–value data structure to represent states of multiple accounts. Keys are an account Address, and values are their state.
Since this implements IImmutableDictionary<TKey,TValue> interface, the usage is same.
A decorator to enable subtype polymorphism for action classes.
By convention, concrete action subclasses are named with verb
One downside of this compared to the vanilla IAction is the fact that it uses reflection under the hood. This may cause compatibility issues on certain platforms, and is slightly slower.
An interface to manipulate account states with maintaining the set of UpdatedAddresses.
It is like a map which is virtually initialized such
that every possible Address exists and
is mapped to
null. That means that:
An in-game action. Every action should be replayable, because multiple nodes in a network should execute an action and get the same result.
A “class” which implements this interface is analogous to a function, and its instance is analogous to a partial function application, in other words, a function with some bound arguments. Those parameters that will be bound at runtime should be represented as fields or properties in an action class, and bound argument values to these parameters should be received through a constructor parameters of that class.
Contextual data determined by a transaction and a block. Passed to Execute(IActionContext) method.
An pseudorandom number generator interface equivalent to Random.
Although these two types have similar shapes, they are not compatible (i.e., disallowed to be casted to each other).
An delegate to provide read-only view of account states.
Gets an account state of the given
If the given
address has never been set
its account status, returns
null instead of throwing
