build library

Provides basic infrastructure for creating state trees.

This library does not provide an application API for defining state trees. Instead it provides the basic protocol for constructing TreeNodes, organizing them into a tree, and providing that tree to a TreeStateMachine.

It is intended that applications will use libraries providing various higher-level APIs for defining state tree, and those libraries will work using the core types in this library. A simple function-based API can be found in delegate_builders library.

// Hypothetical class providing high-level API for defining a state tree
class MyTreeBuilder implements StateTreeBuildProvider {
  // APIs for definining states...

  RootNodeBuildInfo createRootNodeBuildInfo() {
    // Create a RootNodeBuildInfo based on earlier API calls
    // to this builder....
  }
}

var myBuilder = MyTreeBuilder();
// Call myBuilder methods to define a state tree....

// The state machine will call myBuilder.createRootNodeBuildInfo()
var stateMachine = TreeStateMachine(myBuilder);
