Chemistry class

A singleton store of Atoms and Molecules. Atoms and Molecules can be added and used from anywhere in the program.

Example usage:

var chemistry = Chemistry();
chemistry.addAtom(Atom<int>(defaultValue: 0, key: 'someNumber'));
chemistry.addAtom(Atom<int>(defaultValue: 4, key: 'someOtherNumber'));
chemistry.addMolecule(Molecule<int>(
  atoms: [
    chemistry.getAtom<int>('someNumber'),
    chemistry.getAtom<int>('someOtherNumber')
  ],
  computer: (getAtom) => getAtom<int>('someNumber')!.state +
    getAtom<int>('someOtherNumber')!.state,
  key: 'someMolecule',
));

// Somewhere else in the program.
print(chemistry.getMolecule<int>('someMolecule')!.state);

Constructors

Chemistry()

Returns the instance of this store if it exists, otherwise creates it and returns the newly created instance.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

addAtom<T>(Atom<T> atom) → Atom<T>?

Adds an Atom to the store. atom is the Atom to be added to the store.

addMolecule<T>(Molecule<T> molecule) → Molecule<T>?

Adds a Molecule to the store. molecule the Molecule to be added to the store.

dispose() → void

Calls the dispose() method and all atoms and molecules and then removes them. Think of this as a destructor that you have to call.

getAtom<T>(String key) → Atom<T>?

Gets an Atom from the store. key the key of the Atom to get.

getMolecule<T>(String key) → Molecule<T>?

Gets a Molecule from the store. key the key of the Molecule to get.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

removeAtom(String key) → bool

Remove an Atom from the store. key the key of the Atom to remove.

removeMolecule(String key) → bool

Remove a Molecule from the store. key the key of the Molecule to remove.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
